The mammalian hippocampal formation contains several distinct populations of neurons
involved in representing self-position and orientation. These neurons, which include place�…

There are currently a number of theories of rodent hippocampal function. They fall into two
major groups that differ in the role they impute to space in hippocampal information�…

According to schema theory as proposed by Piaget and Bartlett, learning involves the
assimilation of new memories into networks of preexisting knowledge, as well as alteration�…

Hippocampal place cells show position-specific activity thought to reflect a self-localization
signal. Several reports also point to some form of goal encoding by place cells. We�…

Experiences of animal and human beings are structured by the continuity of space and time
coupled with the uni-directionality of time. In addition to its pivotal position in spatial�…

Previous work shows that medial prefrontal cortex (mPFC) cells exhibit spatio-selective
activity at a goal location when rats are trained in a goal-oriented navigation task. Damaging�…

We present a neural network model where the spatial and temporal components of a task
are merged and learned in the hippocampus as chains of associations between sensory�…

The involvement of the caudal hippocampus in spatial learning is presently uncertain,
compared to the well established role of the dorsal region. Therefore voles (Clethrionomys�…

Les travaux sur les bases neurales de la m�moire spatiale sugg�rent l'existence d'un
r�seau neuronal �tendu d�di� au codage de l'information spatiale et permettant l'orientation�…

Cette th�se s' int�resse aux m�canismes permettant de faciliter l'acquisition autonome de
comportements chez les �tres vivants et propose d'utiliser ces m�canismes dans le cadre de�…
