Journal ArticleDOI
A triple dissociation of memory systems: hippocampus, amygdala, and dorsal striatum
TL;DR: The results of this study are consistent with the hypothesis that the mammalian brain may be capable of acquiring different kinds of information with different, more-or-less independent neural systems.
Journal ArticleDOI
Multiple parallel memory systems in the brain of the rat.
TL;DR: A theory of multiple parallel memory systems in the brain of the rat is described, which consists of a series of interconnected neural structures that can be cooperative or competitive, and experimental findings consistent with these ideas are reviewed.
Journal ArticleDOI
A role for adult neurogenesis in spatial long-term memory.
TL;DR: It is shown that new neurons aged 4-28 days old at the time of training are required for long-term memory in a spatial version of the water maze, suggesting a new role for adult neurogenesis in the formation and/or consolidation of long- term, hippocampus-dependent, spatial memories.
Journal ArticleDOI
Parallel information processing in the water maze: evidence for independent memory systems involving dorsal striatum and hippocampus.
TL;DR: These findings suggest that in the absence of a functional neural system that includes dorsal striatum, spatial information predominantly controlled behavior even in the presence of a cue that the animals had previously been reinforced for approaching.
Journal ArticleDOI
The dorsal hippocampus is essential for context discrimination but not for contextual conditioning
TL;DR: Together, these data dissociate hippocampal and nonhippocampal contributions to contextual conditioning, and they provide direct evidence that the hippocampus plays an essential role in the processing of contextual stimuli.
