TL;DR: The hippocampus encodes not only neutral but also valence-related contextual information, and the vCA1-LHA pathway is a direct route by which the hippocampus can rapidly influence innate anxiety behavior.

A Dedicated Population for Reward Coding in the Hippocampus.
TL;DR: A virtual reality task with shifting reward contingencies to distinguish place versus reward encoding revealed a small, specialized cell population that was only active near reward yet whose activity could not be explained by sensory cues or stereotyped reward anticipation behavior.

Parallel emergence of stable and dynamic memory engrams in the hippocampus
TL;DR: The results suggest that synaptic weights along the hippocampal trisynaptic loop are constantly reassigned to support the formation of dynamic representations in downstream hippocampal areas based on a stable code provided by the dentate gyrus.

TL;DR: Findings support a supervised learning model in which activation of the US representation guides the transformation of the CS representation, and the strength of the ensemble-encoded CS–US association predicted the level of behavioural conditioning in each mouse.

CA1 pyramidal cell diversity enabling parallel information processing in the hippocampus.
Ivan Soltesz,Attila Losonczy +1 more
TL;DR: Recent findings supporting a framework in which the hippocampus comprises principal cell subpopulations forming nonuniform parallel circuits that are independently controlled and affect a variety of behaviors are discussed.

Loss of recent memory after bilateral hippocampal lesions.
TL;DR: The results of these studies point to the importance of the hippocampal complex for normal memory function in patients who had undergone similar, but less radical, bilateral medial temporallobe resections, and as a warning to others of the risk to memory involved in bilateral surgical lesions of the hippocampusal region.

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.

TL;DR: It is concluded that the anterior hippocampus and hippocampal gyrus, either separately or together, are critically concerned in the retention of current experience.
