and more recently in animals as well (Eichenbaum, 1997). Furthermore, several recent electrophysiological McGill University Montreal PQH3A 1B1 studies have revealed properties of hippocampal neu-ronal firing patterns that are inconsistent with the notion Canada ‡ Department of Neuroscience and Neurology of a cognitive map and indicate a broader scope of(More)
A large body of experimental evidence suggests that the hippocampal place field system is involved in reward based navigation learning in rodents. Reinforcement learning (RL) mechanisms have been used to model this, associating the state space in an RL-algorithm to the place-field map in a rat. The convergence properties of RL-algorithms are affected by the(More)
Experiments with rodents demonstrate that visual cues play an important role in the control of hippocampal place cells and spatial navigation. Nevertheless, rats may also rely on auditory, olfactory and somatosensory stimuli for orientation. It is also known that rats can track odors or self-generated scent marks to find a food source. Here we model odor(More)
