The survival of the animals depends on their ability to memorize locations and to use behavioral spatial navigation strategies. The crucial structure for this type of behavior and memory is the hippocampus, by its ability to create a cognitive map. In this structure, there are specialized pyramidal cell called place cells. They respond by their complex firing pattern to specific animal's location in the environment. Even though many studies have investigated the role of hippocampal pyramidal cells in spatial navigation and object position discrimination, their function during inaccessible object position discrimination is not yet clarified. In our experiment, rats were trained in a behavioral task to discriminate between rewarded and nor- rewarded positions of object located in an inaccessible space. We investigated the role of individual hippocampal cells during this task by single neuron electrophysiology. The first aim of this study was to decide which of two configurations of objects presented on a computer screen during spatial object discrimination task rats can discriminate easily. The second aim is to show whether and how information about the position of inaccessible objects is represented in the hippocampus using single-neuron electrophysiology. We found out, that animals did not reach...

This licentiate thesis investigates the case and the syntactic position of the direct object in South Saami. The focus is on plural direct objects, which have Differential Object Marking, a phenomenon in which the case alternates between different types of direct objects. In South Saami, some direct objects carry the accusative case form in the plural, while others only carry the plural marker. This variation of suffix displayed on the direct object is contingent on definiteness; definite direct objects consistently display the accusative case form in the plural while indefinite direct objects, specific and nonspecific alike, lack accusative morphology. In addition to case marking, the study presents an analysis of the alternation of the syntactic position of some direct objects. Definite and indefinite specific direct objects can be realized in two positions: as the complement of the verb or in a position as specifier of the light verb projection. By contrast, indefinite nonspecific direct objects obligatorily surface in the complement position of the verb. This variability in syntactic position of some direct objects is analyzed by means of a Specificity Operator, adjoined to the DP-level of every specific NP, definite and indefinite. The operator moves as an instance of quantifier raising in order to take scope over Existential Closure (EC). EC binds NPs in its domain and give them an existential reading. Therefore, when the Specificity Operator raises, it anchors the DP it is adjoined to in a domain, which is unbound by EC and therefore facilitates a specific interpretation. The operator, void of phonological content, can raise alone to the specifier of vP as an instance of covert movement. The operator can also Pied-pipe the DP it is adjoined to, which results in overt movement of the DP. Indefinite nonspecific direct objects lack the Specificity Operator and therefore they remain in-situ in the VP, where they are bound by EC. In addition to its theoretical value, the thesis will be of use for teachers, students and others with an interest in a better understanding of the case form and the position of the direct object in South Saami. / Daennie licentiaatetjaalegisnie gïehtjedem guktie Åarjelsamien direkte objeekth gelliengiertesne kaasushgïetjieh åadtjoeh.

Fokus ligger på direkta objekt i pluralis, vilka uppvisar fenomenet differentiell objektsmarkering, som innebär att vissa direkta objekt bär ackusativsuffixet i plural medan andra endast bär pluralsuffixet. Denna variation i objektsmarkering är känslig för definithet. Definita direkta objekt har accusativändelsen medan indefinita, både specifika och icke-specifika direkta objekt, saknar den. Utöver själva realiseringen av kasussuffix undersöks också de direkta objektens syntaktiska position. En analys presenteras som definierar olika typer av nominalfraser och skiljer definita och specifika direkta objekt från icke-specifika direkta objekt. Den första typen uppvisar variation i sin syntaktiska placering och har möjligheten att dyka upp både i komplementställning till verbet och i en den lilla verbfrasens specificerare, det vill säga vid gränsen för den lexikala fasen. Indefinita icke-specifika direkta objekt, som utgör den andra typen, kan bara uppträda i en position som komplement till verbet. På basis av den analys som inkluderar min innovation Specifikhetsoperatorn, vilken är adjungerad till alla definita och specifika direkta objekts DP-nivå, kan de två positionerna förklaras. Specifikhetsoperatorn flyttar alltid till vP:s specifierare som en kvantifierarinteraktion, där Specifikhetstoperatorn får räckvidd över Existential Closure (EC) och förankrar sin DP i en domän där en specifik tolkning blir nödvändig. Detta är en typ av osynlig flytt. Flytten kan också vara synlig. I det fallet sker medfraktning (Pied-piping) när Specifikhetsoperatorn tar med sig den DP den är adjungerad till när den flyttar till vPs specifierare. Direkta object som saknar Specifikhetsoperatorn stannar i positionen som komplement till verbet och binds därför av EC, vilket leder till att de får en existentiell tolkning. Bortom sitt värde för lingvistisk teoribildning kommer avhandlingen också att bli viktig för lärare, studenter och elever såväl som för andra med ett intresse av att bättre förstå vilket kasus som uppträder på sydsamiska direkta objekt och dessa objekts position i satsen.

The aim of this diploma thesis is to implement a robotic air hockey table in cooperation with the work of Dominik Jašek [37] . Specifically, the work deals with the implementation of simulation software that models behavior of robotic air hockey table, designing a game strategy for the robot and detecting position of a puck situated on the playing field. In addition, the work was extended by integrating said software modules under one control application and creating a user interface for controlling and managing all the functionalities of the robotic table through a capacitive touch screen.
