Aggression and temporal lobe epileptics : a correlational investigation among institutionalized subjects

Otto, Terrance A. January 1980 (has links)
This thesis explored the relationship between temporal lobe epilepsy and aggressive behavior. Prior studies have shown that temporal lobe epileptics display more aggressive behavior than do epileptics with other brain foci. This investigation explored the above mentioned relationship as it exists among the resident population of the New Castle State Hospital. Fifty-three temporal lobe subjects were identified and then matched with respect to age, sex, institutional environment, age of seizure onset, and medication. Frequency of aggressive acts was the dependent variable observed.Temporal lobe epileptics were observed tom differ from the non-temporal lobe epileptics in aggressive behavior. The non-temporal lobe epileptics were found to be significantly more self-aggressive (p<.05). Analysis of aggression towards objects or aggression toward other persons was not significant.

Right medial temporal-lobe contribution to object-location memory

Crane, Joelle. January 1999 (has links)
This thesis includes several studies investigating the right medial temporal-lobe contribution to memory for the location of objects in an array. Three arrays of toy objects were constructed and shown to be comparable in difficulty on the basis of tests with undergraduate students. These arrays were then employed as the test material for examining memory with tasks of immediate or delayed recall within a single trial, in addition to learning-to-criterion across multiple trials. Normal control subjects and patients with unilateral resection from the anterior temporal lobe were tested. The patients had undergone either selective amygdalo-hippocampectomy or anterior temporal lobectomy that either spared or largely invaded the hippocampal formation. The only groups showing impairment were those with large resections from the right hippocampal region; this deficit was noted on immediate recall, delayed recall, and incremental learning of the spatial arrays. In 75 of the patients tested, postoperative magnetic resonance scans were used to measure the extent of tissue remaining in the medial temporal-lobe structures; from multiple regression analyses, the extent of right hippocampus remaining was found to be the best predictor of array-learning performance. The notion that the hippocampus encodes spatial information in a map-like or allocentric manner (O'Keefe and Nadel, 1978) was explored by requiring normal control subjects and patients with unilateral temporal-lobe lesions to reconstruct the spatial arrays from a vantage-point other than that from which they had previously viewed the arrays. Contrary to prediction, the allocentric manipulation failed, in general, to elicit any additional impairment. Taken together, the results indicate that damage limited to the medial-temporal region in the right hemisphere is sufficient to disrupt memory for the location of objects. Within this region, the hippocampus appears to be the most critical structure for building, over suc

Devido a EDQc ser formulado em um ambiente de alto controle de suas propriedades materiais, consideramos que um ou mais parâmetros do sistema sofre modulações temporais periódicas impostas externamente, o que caracteriza um sistema de EDQc não-estacionário. Construímos um formalismo matemático fechado utilizando a base de estados vestidos para descrever o comportamento geral do sistema. A principal equação que descreve a dinâmica do circuito é deduzida de acordo com um método consistente de aproximação, o famigerado método da RWA, que é justificado e generalizado neste trabalho. Da equação principal, descreveremos a dinâmica para modulações simultâneas e multifrequências, onde cada efeito físico será caracterizado pelo valor estipulado a frequência de modulação. Efeitos já conhecidos são recuperados rigorosamente, como: o efeito Casimir dinâmico (ECD) e o regime anti-Jaynes Cummings (AJC). Além desses efeitos, identificamos um novo comportamento, o anti-efeito Casimir dinâmico (AECD), onde um par de excitações pode ser coerentemente aniquilado devido à modulação de um ou mais parâmetro do sistema. Construímos Hamiltoniano efetivo que descreve a criação de pares de fótons via ECD, e propomos um Toy Model para o ECD na presença de uma placa dielétrica oscilante, vista como um conjunto de átomos de dois-níveis. O nosso modelo prediz que o crescimento do número médio de fótons na cavidade é limitado devido à presença de um termo não-linear no Hamiltoniano efetivo - o termo Kerr. Por último, discutimos a criação de estados quânticos emaranhados devido a possíveis modulações do sistema em diferentes regimes de parâmetros. ____________________________________________________________________________________ ABSTRACT / In this work we consider the circuit Quantum Electrodynamics (circuit QED) architecture to study the interaction between an “artificial atom”and a single mode of the quantized Electromagnetic field confined in a microwave waveguide resonator on a superconducting chip. The circuit QED is formulated in the solid state environment where the material properties are highly controllable, so we consider that one or more system parameters undergo periodic time-modulation prescribed externally. This regime characterizes the nonstationary circuit QED. By writing the wavefunction in the “dressed states”basis we develop a closed mathematical formalism to describe the general behavior of the system. The main equation that describes the dynamics of the circuit is derived using a consistent method of successive approximations employing the Rotating Wave Approximation (RWA), which is justified and generalized in our work. From the main equation we will describe the dynamics for a single-tone and multitone modulations, pointing out that each physical effect takes place for a well defined modulation frequency. We derive in a rigorous manner the previously known effects, such as the dynamical Casimir effect (DCE) and the Anti-Jaynes-Cummings behavior. Besides, we discover a new effect we coined Anti-DCE, when a pair of system excitations can be coherently annihilated due to the modulation of one or more system parameters. We also deduce a effective Hamiltonian that describes the photon generation from vacuum via DCE and propose a Toy Model for the DCE in the presence of a oscillating dielectric slab, pictured as a set of noninteracting two-level atoms. Our model predicts that the photon growth is limited due to the presence of a nonlinear term in the effective Hamiltonian, namely, the Kerr term. Finally, we discuss schemes to create entangled light-matter states by means of the system modulation in different regimes of parameters.

Patrón de invervación del músculo temporal humano en cadáveres al aplicar el método de Sihler

Sanzana Luengo, Cristina Fernanda January 2015 (has links)
Trabajo de Investigación Requisito para optar al Título de Cirujano Dentista / Autor no autoriza el acceso a texto completo de su documento / Introducción: El propósito de este estudio descriptivo fue caracterizar el patrón de inervación al interior del músculo temporal otorgado por los nervios temporal profundo anterior, temporal profundo medio y temporal profundo posterior. Ya que si bien se ha descrito su neuroanatomía, esta no se ha realizado con precisión por las limitaciones que tiene la disección anatómica. Por esta razón, se utilizó el método de Sihler que es una técnica diferente y permite observar la distribución nerviosa en los tres sentidos del espacio sin perder su relación con las fibras musculares. Finalmente se propone en el presente estudio una descripción anatómica del patrón de inervación del músculo temporal, aportando información esencial tanto para la literatura morfológica del territorio craneofacial como para la terapéutica de distintas patologías donde el músculo temporal esté implicado. Metodología: Se realizó disección anatómica de ocho músculos temporales de cadáveres conservados. Las muestras fueron sometidas al método de tinción de Sihler que permitió transparentar las fibras musculares y teñir de color violeta los troncos nerviosos. Luego, se observaron bajo lupa estereoscópica y transiluminación. Se realizó fotografía estandarizada dividiendo al músculo en tres regiones para su posterior análisis y se caracterizó el patrón de inervación visualizado mediante software computacional. Resultados: Se obtuvo ocho músculos disecados y teñidos adecuadamente. Se determinó la presencia de tres troncos nerviosos principales que discurren con la misma dirección y sentido en todos los casos. Se observó que existen ramos colaterales provenientes de cada tronco principal los que en forma de arco comunican tres regiones. Finalmente se estableció un patrón de inervación común a todos los músculos a través de una descripción anatómica y un esquema representativo. Conclusión: Existe un patrón de inervación común para todos los músculos estudiados.

Extensão de um SGBD para incluir o gerenciamento da informação temporal. / Extension of a DBMS to include the management of temporal information.

Rodrigo Katsumoto Sakai 09 August 2007 (has links)
O fator temporal é uma variável natural da maioria dos sistemas de informação, pois no mundo real os eventos ocorrem de maneira dinâmica, modicando continuamente os valores dos seus objetos no decorrer do tempo. Muitos desses sistemas precisam registrar essa modicação e atribuir os instantes de tempo em que cada informação foi válida no sistema. Este trabalho reúne as características relacionadas aos Bancos de Dados Temporais e Bancos de Dados Objeto-Relacionais. O objetivo primordial é propor uma forma de implementar alguns aspectos temporais, desenvolvendo um módulo que faça parte das características e funcionalidades internas de um SGBD. O módulo temporal contempla principalmente a parte de restrições de integridade temporal que é utilizada para manter a consistência da informação temporal armazenada. Para isso, é proposto um novo tipo de dado que melhor representa as marcas temporais dos objetos. Uma parte importante para a implementação desse projeto é a utilização de um SGBD objeto-relacional que possui algumas características orientadas a objetos que permitem a extensão de seus recursos, tornando-o capaz de gerenciar alguns aspectos temporais. O módulo temporal desenvolvido torna esses aspectos temporais transparentes para o usuário. Por conseqüência, esses usuários são capazes de utilizar os recursos temporais com maior naturalidade. / The temporal factor is a natural variable of the majority of the information systems, therefore in the real world the events occur in dynamic way, modifying continuously the values of its objects in elapsing of the time. Many of these systems need to register this modication and to attribute the instants of time where each information was valid in the system. This work congregates the characteristics related to the Temporal Databases and Object-Relational Databases. The primordial objective is to consider a form to implement some temporal aspects, developing a module that is part of the characteristics and internal functionalities of a DBMS. The temporal module mainly contemplates the part of restrictions of temporal integrity that is used to keep the consistency of the stored temporal information. For this, a new data type is proposed that better represent the objects timestamps. An important part for the implementation of this project is the use of a object-relational DBMS that has some object-oriented characteristics that allow the extension of its resources, becoming capable to manage some temporal aspects. The developed temporal module becomes these transparent temporal aspects for the user. For consequence, these users are capable to use the temporal resources more naturally.
