The contemporary society of the United States of America is becoming an increasingly stressful environment to live in. Our rapid advances and developments in virtual, electronic, and high-speed technology have led us to a lifestyle that operates more quickly. However, our attachment to such a face-paced lifestyle has unfortunately led us towards an increasingly stressful lifestyle. This research focuses on identifying our current society's perceptual outlook and illustrating how the practice of mindfulness can help reduce the anxieties, struggles, and mental flaws which cloud our perception. The intent of this thesis is to show how the practice of mindfulness is beneficial towards our mental health. The practice of mindfulness originated within the Buddhist tradition and has evolved into a new area of interest in the fields of mental health, psychology, philosophy, and humanities. Also, the connection between the practice of mindfulness, and the practice of authentic creativity, as demonstrated in playing the piano, is illuminated within this research. Authentic creativity thus serves as an enlightening metaphor for the elusive practice of mindfulness, and creates a more vivid understanding of the concept of mindfulness. For this thesis I have conducted a literature review in the areas of philosophy, religion, aesthetics and cognitive science. Also, I am actively participating in my research by personally practicing mindfulness and piano. Part of my methodology involves critical thinking on the personal level as I am writing journal entries about my views and thoughts concerning these processes.

<p>This thesis explores the intersection of storytelling and spirituality in contemporary Native literature in Canada. The invocation of the oral tradition and its history will be examined in the works of Eden Robinson, Joseph Boyden, and Harry Robinson, as each author attempts to orient his or her narratives within a First Nations framework. By gesturing towards orality in their written literature, these authors acknowledge the dialogic nature of a narrative that has been shaped by ancestral experiences and memory and thus write against the colonial master narrative of the contemporary Canadian nation-state. In Joseph Boyden's <em>Through Black Spruce</em>, Eden Robinson's <em>Monkey Beach</em>, and the transcribed collections of Harry Robinson's stories, the invocation of orality becomes the vehicle through which to explore Indigenous ways of knowing and traditional spiritual beliefs. This thesis first considers the ways in which the mode of storytelling allows each author to create a new narrative that introduces readers to an Indigenous perspective on the processes of history. It then examines the evolution of specific spiritual beings from traditional narratives into contemporary settings as a way to explore neocolonial attitudes and the compromised contexts of modern Indigenous life in communities across Canada that continue to be haunted by a legacy of colonialism. I end with an exploration of the potential for healing that each author envisions as communities move into a decolonization process through the regeneration of tribal languages, a reconnection to sacred space, and a reimagining of the Canadian master narrative and its colonial interpretation of history.</p> / Master of English

BACKGROUND:In a globalized word, prevention of infectious diseases is a major challenge. Rapid detection of viable virus particles in water and other environmental samples is essential to public health risk assessment, homeland security and environmental protection. Current virus detection methods, especially assessing viral infectivity, are complex and time-consuming, making point-of-care detection a challenge. Faster, more sensitive, highly specific methods are needed to quantify potentially hazardous viral pathogens and to determine if suspected materials contain viable viral particles. Fourier transform infrared (FTIR) spectroscopy combined with cellular-based sensing, may offer a precise way to detect specific viruses. This approach utilizes infrared light to monitor changes in molecular components of cells by tracking changes in absorbance patterns produced following virus infection. In this work poliovirus (PV1) was used to evaluate the utility of FTIR spectroscopy with cell culture for rapid detection of infective virus particles.RESULTS:Buffalo green monkey kidney (BGMK) cells infected with different virus titers were studied at 1 - 12 hours post-infection (h.p.i.). A partial least squares (PLS) regression method was used to analyze and model cellular responses to different infection titers and times post-infection. The model performs best at 8 h.p.i., resulting in an estimated root mean square error of cross validation (RMSECV) of 17 plaque forming units (PFU)/ml when using low titers of infection of 10 and 100 PFU/ml. Higher titers, from 103 to 106 PFU/ml, could also be reliably detected.CONCLUSIONS:This approach to poliovirus detection and quantification using FTIR spectroscopy and cell culture could potentially be extended to compare biochemical cell responses to infection with different viruses. This virus detection method could feasibly be adapted to an automated scheme for use in areas such as water safety monitoring and medical diagnostics.

Le trouble obsessionnel-compulsif (TOC) est un trouble anxieux fréquent et invalidant. Pour un grand nombre de patients, il existe une résistance aux thérapeutiques actuellement disponibles, soulignant toute l'importance de mieux préciser la physiopathologie du TOC. Le principal objectif de cette thèse est d’étudier les altérations anatomiques et fonctionnelles des voies thalamo-corticales intéressant le cortex orbitofrontal (COF) et le cortex cingulaire antérieur (CCA) dans le TOC. Pour cela, nous avons utilisé plusieurs outils complémentaires permettant d’appréhender cette problématique sous différents angles méthodologiques.Concernant les altérations anatomiques associées au TOC, nous avons rapporté les données de méta-analyses des études de neuro-imagerie volumétrique et morphométrique ainsi que les résultats d'une étude originale d'imagerie volumétrique. Une diminution du volume orbitofrontal, une augmentation du volume thalamique et une relation entre ces modifications de volumes ont été observées chez les patients avec TOC comparativement aux témoins. Les modifications de densité de matière grise concernaient le COF et le putamen dans le sens d'une augmentation et les cortex pariétal et préfrontal dorsolatéral dans le sens d'une diminution dans le TOC.Concernant les altérations fonctionnelles associées au TOC, nous avons détaillé un travail de méta-analyse des études d'imagerie fonctionnelle, un travail expérimental chez le primate basé sur des manipulations pharmacologiques intra-cérébrales, puis un travail expérimental chez l'homme reposant sur le développement d'une tâche comportementale originale couplée à l'imagerie fonctionnelle. Dans notre méta-analyse, nous avons décrit la participation fonctionnelle de régions comme le COF, le thalamus et le striatum lorsque des symptômes obsessionnels et compulsifs étaient provoqués chez des patients. Chez le primate subhumain, nous avons montré qu'une hyperactivation du noyau ventral-antérieur, par levée de l'inhibition GABAergique, entraînait l'apparition de comportements pseudo-compulsifs. Ensuite, à l'aide d'une tâche originale qui mettait les sujets en situation de vérifier, nous avons mis en évidence que les dysfonctions orbitofrontales associées au doute lors de la prise de décision n'étaient pas modulées ni par les informations contextuelles (signaux d'erreur), ni par la réponse comportementale chez les patients avec TOC comparativement à des sujets témoins.Enfin, la superposition des cartes morphométriques et fonctionnelles a trouvé une relation entre les altérations anatomiques et fonctionnelles au sein du COF. Nos résultats soulignent toute l'importance des voies thalamo-orbitofrontales dans la physiopathologie du TOC. / Obsessive-compulsive disorder (OCD) is a frequent and disabling anxiety disorder. Available treatments are effective for most patients but impairing residual symptoms and treatment resistance are common in OCD patients. Therefore, a better understanding of OCD pathophysiology is essential for further improvement of therapeutic strategies. The main goal of my thesis was to assess the anatomical and funtional thalamocortical alterations associated with OCD. Concerning the anatomical thalamocortical alterations associated with OCD, we conducted two meta-analyses of anatomical neuroimaging studies and an original volumetric neuroimaging study. We reported a smaller thalamic volume and a greater orbitofrontal volume, but also an inverse relationship between the volume changes in OCD patients compared with healthy subjects. Furthermore, we showed that gray matter density within the orbitofrontal cortex and the putamen were enhanced in OCD. Concerning the functional thalamocortical alterations associated with OCD, we reported data coming from a meta-analysis of functional neuroimaging studies, an experimental study in subhuman primates using local brain pharmacological manipulations and an event-related neuroimaging study in OCD patients. In our meta-analysis, we showed that the orbitofrontal cortex, the thalamus and the striatum were involved in the mediation of OCD symptoms. In subhuman primates, the pharmacologically induced overactivity within the ventralanterior thalamic nucleus leaded to the emergence of compulsive-like behaviors. Then, in our neuroimaging study, we found that doubt-related orbitofrontal dysfunctions were not modulated by neither error signals nor compulsive-like behaviors in OCD patients, compared with healthy subjects. Finally, we described by using meta-analytic data that anatomical and functional brain alterations overlap with the lateral orbitofrontal cortex in OCD. In conclusion, our results suggest that the thalamo-orbitofrontal network may play a primary role in the genesis and mediation of OCD symptoms.

L’exposition du fœtus à l’éthanol est reconnue comme étant la principale cause de maladies évitables lors du développement. Une forte exposition à l’alcool durant la gestation peut occasionner des dysmorphies cranio-faciales et des retards mentaux, ainsi que des troubles d’apprentissages et du comportement. Le développement du système visuel est également perturbé chez une grande majorité d’enfants qui ont été exposés à l’alcool. Lorsque les doses prises sont élevées, le système visuel peut présenter une panoplie de symptômes comme une augmentation de la tortuosité des vaisseaux rétiniens, de la myopie, de l’hypermétropie, du strabisme et une hypoplasie du nerf optique. Cependant, très peu d’études se sont penchées sur les effets de plus faibles doses sur le développement du système visuel du primate. Le singe est un excellent modèle pour étudier le système visuel car il possède plusieurs similitudes avec l’humain tant au niveau développemental qu’au niveau structurel. De plus, le singe utilisé, le Chlrocebus aethiops sabeus, possède l’avantage que des individus de cette espèce ont une consommation naturelle et volontaire à l’alcool. Une étude (Clarren et al., 1990) a suggéré qu’une faible exposition à l’alcool du fœtus du primate non humain occasionnait une diminution du nombre de cellules ganglionnaires de la rétine (CGRs). Étant donné que le corps genouillé latéral dorsal (CGLd) reçoit la plupart de ses intrants de la rétine, il est raisonnable d’assumer que les couches rétino-récipientes du CGLd devraient être aussi affectées. Nous avons alors émis l’hypothèse que le CGLd devrait également subir une diminution du nombre de neurones. Pour la première fois, nous avons utilisé une méthode stéréologique pour quantifier le nombre de cellules dans les couches parvo- (P) et magnocellulaires (M) du CGLd. Contrairement à notre hypothèse de départ, nous n’avons pas observé de diminution dans le nombre global de neurones dans le CGLd des animaux exposés à l’alcool par rapport à des sujets contrôles, ni une diminution de son volume. Nous avons toutefois observé une diminution de la taille du corps cellulaire seulement dans la population M du CGLd. Ces résultats suggèrent que le système visuel est affecté par une faible exposition à l’alcool durant son développement qui devrait se traduire sur le comportement par des déficits dans les fonctions de la voie M. / An alcohol exposition during the gestation is recognized as the leading causes of preventable developmental disorders. A heavy exposure to ethanol can lead to a litany of symptoms ranging from cranio-facial dysmorphology and mental retardation to developmental learning and behavioural disorders. The visual system development is also the target for a high percentage of children exposed prenatally to alcohol. When the concentrations are relatively high, the visual system can show signs of increased tortuosity of the retina vessels, myopia, hyperopia, strabismus and hypoplasia of the optic nerve. Few studies have examined the effects of a moderate exposure to alcohol on the development of the primate visual system. The monkey is an excellent model to study the visual system because this model owns a lot of similarities with human at the developmental and structural levels. Moreover, the monkey used for this study, Chlrocebus sabeus, naturally and voluntarily consumes alcohol. One study (Clarren et al., 1990) suggested that a low dose exposure of alcohol induce a diminution of neurons in the ganglion retinal cell population. But, no information is given about the numbers and the cell population of neurons. We hypothesized that the lateral geniculate nucleus (LGN) should show a decrease in the number of neurons after moderate prenatal exposure to alcohol. The LGN is a key region because it is situated between the region that receives visual information, the retina, and the first visual region that analyzes the visual information, the primary visual cortex (V1). We utilized a stereological method to study the effects of moderate doses of alcohol on the neuronal population of the LGN in the non-human primate. In opposition to our hypothesis, we have not observed any diminution in the number of neurons or the volume of the LGN. However, we have found a diminution in the neuronal volume of only the magnocellular (M) region. These results suggest that the visual system is affected by a low dose of alcohol that should translate into deficits in the functions of the M pathway.

Le cannabis produit de nombreux effets psychologiques et physiologiques sur le corps humain. Les molécules contenues dans cette plante, désignées comme « phytocannabinoïdes », activent un système endogène qu’on appelle le système endocannabinoïde (eCB). Les effets de la consommation de cannabis sur la vision ont déjà été décrits sans cependant de formulation sur les mécanismes sous-jacents. Ces résultats comportementaux suggèrent, malgré tout, la présence de ce système eCB dans le système visuel, et particulièrement dans la rétine. Cette thèse vise donc à caractériser l’expression, la localisation et le rôle du système eCB dans la rétine du singe vervet, une espèce animale ayant un système visuel semblable à celui de l’humain. Nous avons mis au point un protocole expérimental d’immunohistochimie décrit dans l’article apparaissant dans l’Annexe I que nous avons utilisé pour répondre à notre objectif principal. Dans une première série de quatre articles, nous avons ainsi caractérisé l’expression et la localisation de deux récepteurs eCBs reconnus, les récepteurs cannabinoïdes de type 1 (CB1R) et de type 2 (CB2R), et d’un 3e présumé récepteur aux cannabinoïdes, le récepteur GPR55. Dans l’article 1, nous avons démontré que CB1R et une enzyme clé de ce système, la fatty acid amide hydrolase (FAAH), sont exprimés dans les parties centrale et périphérique de la rétine, et abondamment présents dans la fovéa, une région où l’acuité visuelle est maximale. Dans l’article 2, nous avons localisé le CB2R dans des cellules gliales de la rétine : les cellules de Müller et nous avons proposé un modèle sur l’action de cette protéine dans la fonction rétinienne faisant appel à une cascade chimique impliquant les canaux potassiques. Dans l’article 3, nous avons observé le GPR55 exclusivement dans les bâtonnets qui sont responsables de la vision scotopique et nous avons soumis un deuxième modèle de fonctionnement de ce récepteur par le biais d'une modulation des canaux calciques et sodiques des bâtonnets. Vu que ces 3 récepteurs se retrouvent dans des cellules distinctes, nous avons suggéré leur rôle primordial dans l’analyse de l’information visuelle au niveau rétinien. Dans l’article 4, nous avons effectué une analyse comparative de l’expression du système eCB dans la rétine de souris, de toupayes (petits mammifères insectivores qui sont sont considérés comme l’étape intermédiaire entre les rongeurs et les primates) et de deux espèces de singe (le vervet et le rhésus). Ces résultats nous ont menés à présenter une hypothèse évolutionniste quant à l’apparition et à la fonction précise de ces récepteurs. Dans les articles subséquents, nous avons confirmé notre hypothèse sur le rôle spécifique de ces trois récepteurs par l’utilisation de l’électrorétinographie (ERG) après injection intravitréenne d’agonistes et d’antagonistes de ces récepteurs. Nous avons conclu sur leur influence indéniable dans le processus visuel rétinien chez le primate. Dans l’article 5, nous avons établi le protocole d’enregistrement ERG normalisé sur le singe vervet, et nous avons produit un atlas d’ondes ERG spécifique à cette espèce, selon les règles de l’International Society for Clinical Electrophysiology of Vision (ISCEV). Les patrons électrorétinographiques se sont avérés semblables à ceux de l’humain et ont confirmé la similarité entre ces deux espèces. Dans l’article 6, nous avons démontré que le blocage de CB1R ou CB2R entraine une modification de l’électrorétinogramme, tant au niveau photopique que scotopique, ce qui supporte l’implication de ces récepteurs dans la modulation des ondes de l’ERG. Finalement, dans l’article 7, nous avons confirmé le modèle neurochimique proposé dans l’article 3 pour expliquer le rôle fonctionnel de GPR55, en montrant que l’activation ou le blocage de ce récepteur, respectivement par un agoniste (lysophosphatidylglucoside, LPG) ou un antagoniste (CID16020046), entraine soit une augmentation ou une baisse significative de l’ERG scotopique seulement. Ces données, prises ensemble, démontrent que les récepteurs CB1R, CB2R et GPR55 sont exprimés dans des types cellulaires bien distincts de la rétine du singe et ont chacun un rôle spécifique. L’importance de notre travail se manifeste aussi par des applications cliniques en permettant le développement de cibles pharmacologiques potentielles dans le traitement des maladies de la rétine. / Cannabis produces a range of psychological and physiological effects on the human body. Cannabinoids are the chemical compounds found in cannabis that activate an endogenous system, termed the endocannabinoid (eCB) system. Reports made in the 1970s have noted that cannabis consumption affects vision. It is therefore suggested that the eCB system is present in the visual system, particularly in the retina. This thesis aims at characterizing the expression, localization, and role of the eCB system in the vervet monkey retina. This animal model has a similar visual system as humans. Using immunohistochemistry methods presented in the article of Annexe I, we have established an experimental protocol to answer our goal. In the first series of four articles, we have characterized the expression and localization of the cannabinoid receptor 1 (CB1R), cannabinoid receptor 2 (CB2R), and the putative cannabinoid receptor GPR55. In Article 1, we have demonstrated that CB1R and a key enzyme of this system, FAAH (fatty acid amide hydrolase), are expressed in the central and peripheral retina, but heavily present in the fovea, the retinal region responsible for high acuity vision. In Article 2, we have localized CB2R in the glial Müller cells and hypothesized a possible mechanism of action of CB2R involving potassium buffering. In Article 3, we found that GPR55 is exclusively expressed in rods and have proposed its role through the modulation of calcium and sodium channels in rods. Given that these three receptors are segregated in the vervet monkey retina, we suggested that they might have distinct roles in retinal physiology. In Article 4, we reported a comparative analysis of the expression of the eCB system components in the retina of rodents, tree shrews (small mammals considered as early primates), and monkeys. This paper provides evidence that the eCB system is differently expressed in the retina of these mammals and suggests a distinctive role of eCBs in visual processing. In the subsequent series of three articles, we confirmed their suggested roles in the retina by using electroretinography (ERG) and intravitreal injections of agonist and antagonist of these receptors. We concluded that they indeed play important roles in the retina. In Article 5, we developed a standard protocol for ERG testing in our animal model and have published an ERG atlas with normalized amplitudes and latency values similar to that of humans, following the guidelines of the International Society for Clinical Electrophysiology of Vision. In Article 6, we showed that blockade of CB1R or CB2R with specific antagonists modifies the ERG, both in photopic and scotopic conditions, which confirms the implication of these receptors in normal retinal function. Finally, in Article 7 (expression of GPR55 in rods only), we confirmed the suggest role of GPR55 in rods by showing that activation or blockade of GPR55 with a specific agonist (lysophosphatidylglucoside) or antagonist (CID16020046) increases or decreases the amplitude of the scotopic ERG waveforms. Taken together, these articles demonstrate that CB1R, CB2R, and GPR55 are differentially expressed in the vervet monkey retina and have distinct roles. This work has also clinical relevance in the way that we have discovered new pharmacological targets that can be used for treatment of many retinal diseases.

A Bioacoustica oferece ferramentas úteis para diversas ciências e práticas na utilização acadêmica, científica, aplicada e conservação da vida animal. Nossa hipótese é que as chamadas naturais, como o rugido de longo alcance do bugios preto, atuam como elemento de enriquecimento ambiental, se a sua execução aumenta a exibição de um comportamento natural em cativeiro. O bugio faz um uso diário do rugido e sua emissão é conhecida por evocar respostas de outros bandos de bugio em vida livre. Para testar a eficácia dos rugidos em melhorar o bem-estar foi realizado um experimento no Bosque e Zoológico Fábio Barreto, no município de Ribeirão Preto, onde treze indivíduos (6 fêmeas e 7 machos) viviam em cinco recintos adjacentes. Eles tiveram contato visual e acústico entre eles e com outras duas espécies de primatas e outros grupos de vida livre de bugio preto. Adotoamos o delineamento experimental ABABA, em que fases controle A foram intercaladas com o tratamento (playback de rugido) nas fases B, duas vezes ao dia (manhã e tarde). Na primeira fase B, o estímulo foi sempre tocado no mesmo horário (previsível) e, na segunda fase tratamento, horários aleatórios foram adotados (imprevisível). Nós avaliamos as alterações na duração relativa de 6 comportamentos entre as fases A e B, entre sexo e em ambos os períodos, com o teste ANOVA de medidas repetidas. Nós notamos um aumento no comportamento natural da espécie em fases de tratamento, como alerta, atenção dirigida, e interações sociais, juntamente com a diminuição de comportamentos estereotipados, sugerindo melhoria do bem-estar. As emissões naturais de rugidos também aumentaram. Concluímos que ambos os tratamentos, previsível e imprevisível, melhoraram o bem-estar e propomos a utilização da reprodução de chamadas específicas de especies como uma nova categoria de enriquecimento ambiental. A resposta dos outros primatas nos levou a concluir que houve um efeito sobre animais vizinhos que pode ser benéfico ou prejudicial de acordo com a espécie e a condição psicológica dos animais. / The Bioacoustics offers useful tools for diverse academic, scientific and applied sciences and practices in use and conservation of animal life. We hypothesized that natural call, as the loud roar of the black-howler monkey, would act as environmental enrichment element if its execution increased the display of natural behavior in captivity. The howler-monkey makes an everyday use of the roar and its emission is known to evoke free-living howler-monkeys to call back in response. To test the effectiveness of roars in improving welfare we conducted an experiment in Bosque e Zoológico Fábio Barreto, in the municipality of Ribeirão Preto where thirteen individuals (6 females and 7 males) were living in five adjacent enclosures. They had visual and acoustic contact between them and with two other primate species and a free-living black-howler monkey group. We adopted the ABABA experimental design, in which control phases A were interspersed with treatment (roar playback) phases B, two times a day (morning and afternoon). In the first B phase, the stimulus was always played at the same time (predictable) and, in the other different random schedules were adopted (unpredictable). We evaluate changes in relative duration of 6 behaviors from A to B phases, between sex and in both periods with a repetitive factorial ANOVA. We reported increase in natural behavior of the species in treatment phases, as alert, oriented attention, and social interactions, coupled with the decrease of stereotyped behaviors, suggesting welfare improvement. Thus, natural emissions of roars also increased. We concluded that both predictable and unpredictable routines improved welfare and we propose the use of playback of specie-specific calls as a new category of environmental enrichment. The answer of the other primates led us to conclude that there was a neighborhood effect that can be beneficial or harmful according to the species and the psychological condition of the animals.

O albinismo é um conjunto de alterações fenotípicas caracterizadas pela incapacidade de produzir melanina, fazendo com que a pigmentação de alguns órgãos seja reduzida ou ausente. Discutem-se quais efeitos esta redução ou ausência de pigmentação, na retina, poderia ter sobre a capacidade visual do indivíduo. A visão de cores apresenta um papel muito importante para a sobrevivência e desenvolvimento de primatas. A capacidade de discriminar visualmente o alvo de um fundo apenas pela diferença de matiz pode ser o diferencial tanto para a busca de alimentos, como para a fuga de predadores. Estudos sobre a visão de cores auxiliam a fazer inferências sobre suas bases biológicas e utilidade funcional. Pretendeu-se com esse estudo elucidar a discriminação de cores de um indivíduo albino de Sapajus sp, por meio de uma avaliação psicofísica utilizando-se de uma versão modificada do teste computadorizado Cambridge Colour Test (CCT), e uma análise genética de DNA, para identificar os genes que codificam as opsinas. Os arranjos genótipo/fenótipo inferidos do indivíduo a partir das elipses foram comparados à composição dos genes que codificam opsina, obtida por análise independente de DNA. Buscou-se, assim, identificar possíveis prejuízos à visão de cores causados pelo albinismo, em relação a Sapajus normais. Apesar dos vários problemas decorrentes do albinismo, o sujeito experimental aprendeu a tarefa com sucesso e apresentou, nos testes, limiares de discriminação de cores característicos de dicromacia do tipo deuterânope com valores dentro dos esperados para o gênero Sapajus. Os resultados comportamentais foram condizentes com o fenótipo inferido a partir da análise genética / São Paulo Albinism is a set of phenotypic traits, characterized by the inability to produce melanin, that way the pigmentation of some organs are either reduced or absent. There is no consent on what effects this lower or none pigmentation on retina could lead on subject vision. The color vision represents a major role on primates survival and development. The capacity of visually discriminate targets only by hue differences from the background can be used either to search for food or to avoid predators. Studies on color vision help to make inference on their biological bases and functional utility. This study aimed to elucidate the color vision discrimination of an albino subject of Sapajus sp, through a psychophysical evaluation using a modified version of Cambridge Colour Test (CCT) and a genetic analyses of DNA in order to identify genes that codify the opsin. The correlation between genotype and phenotype were inferred by comparison between discrimination ellipses and genetic composition of genes that code opsin. Thus seeking to identify possible color vision losses caused by albinism comparing those analyses with healthy Sapajus. Despite many problems associated to albinism, the test subject successfully learn the task and his test showed color discrimination thresholds of a deuteranope dichromacy with values within the expected to subjects of Sapajus genera. Those behavioral results where consistent with the phenotype predicted by the genetic analyses
