TLDR
Results showed that hippocampectomized animals learned the initial two-tone discrimination at rates equivalent to operated control animals and animals with neocortical lesions, but during reversal conditioning, animals with hippocampal lesions were severely impaired relative to both other groups.About:

Journal ArticleDOI
Memory and the hippocampus: A synthesis from findings with rats, monkeys, and humans.
TL;DR: The role of the hippocampus is considered, which is needed temporarily to bind together distributed sites in neocortex that together represent a whole memory.
Journal ArticleDOI
Neurogenesis in the adult is involved in the formation of trace memories
TL;DR: It is shown that a substantial reduction in the number of newly generated neurons in the adult rat impairs hippocampal-dependent trace conditioning, a task in which an animal must associate stimuli that are separated in time.

Double dissociation of conditioning and declarative knowledge relative to the amygdala and hippocampus in humans
Antoine Bechara,Daniel Tranel,Hanna Damasio,Ralph Adolphs,Charles Rockland,Antonio R. Damasio +5 more
TL;DR: A patient with selective bilateral damage to the amygdala did not acquire conditioned autonomic responses to visual or auditory stimuli but did acquire the declarative facts about which visual or audio stimuli were paired with the unconditioned stimulus.
Journal ArticleDOI
The Structure and Organization of Memory
TL;DR: The concept of brain systems, while not entirely free of problems itself, provides a more concrete and in the end a more satisfying basis for thinking about memory systems.
Journal ArticleDOI
An emerging concept. The cerebellar contribution to higher function.
TL;DR: A critical review of both earlier and more current clinical observations that raise the possibility that the cerebellum may contribute to the modulation of higher order behavior is presented, as well as a review of the salient laboratory data that appear to support this contention.

Preserved learning and retention of pattern-analyzing skill in amnesia: dissociation of knowing how and knowing that
TL;DR: The results indicate that the class of preserved learning skills in amnesia is broader than previously reported and support the hypothesis that such a distinction is honored by the nervous system.
Journal ArticleDOI
Hippocampus, space, and memory
TL;DR: It is proposed that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material (spatial or nonspatial) that is to be processed by that memory.

An autoradiographic study of the organization of the efferet connections of the hippocampal formation in the rat
Larry W. Swanson,W. M. Cowan +1 more
TL;DR: The efferent connections of the hippocampal formation of the rat have been re‐examined autoradiographically following the injection of small quantities of 3H‐amino acids into different parts of Ammon's horn and the adjoining structures to indicate quite clearly that each component of the hippocampusal formation has a distinctive pattern ofefferent connections.
Journal ArticleDOI
The hippocampus and contextual retrieval of information from memory: A theory
TL;DR: A theory which holds that information is normally stored within a specialized memory rather than the system immediately responsible for the performance of behavior is advanced and the effects of hippocampal ablation are explained in terms of the elimination of such transfer.
