Declarative memory is characterized as a conscious, explicit memory. Declarative memory consists of two essential systems, semantic memory and episodic memory. Episodic memory enables us to recall specific past events. A simplified model, so called Episodic-like memory is often used to study episodic memory mechanisms. According to this model, all events are stored in a contextual framework consisting of three basic components: identity of the object ('what' happened), temporal information ('when' it occurred) and spatial information ('where' did it happen). This type of memory is testable not only in humans but also in animal models. Aim of this diploma thesis is to study the neuronal substrate of individual components of episodic memory in healthy volunteers by means of functional magnetic resonance imaging (fMRI) and ecologically valid tasks designed in virtual reality environment. Results obtained in the fMRI paradigm show that apart from common neuronal substrate of episodic memory, additional brain structures are responsible for recollection of individual components of the episodic-like memory. Behavioral data indicate that the demands of the recollection of individual components is not equivalent. Additional analyses with parcellation of the brain to individual structures and consecutive...
