Sep 19, 2023 · In psychology, the hippocampus is a crucial structure within the brain’s medial temporal lobe. It plays a vital role in forming and retrieving memories, spatial navigation, and emotional responses. Damage to the hippocampus can lead to memory impairments and difficulty forming new memories, highlighting its importance in learning and cognition.
In rodents, the hippocampus and entorhinal cortex are believed to be central for cognitive map-based navigation. In human fMRI studies, the hippocampus responds when people use a cognitive-map-based strategy during virtual navigation, as evidenced by the use of short-cuts or the planning of efficient novel routes 18 – 20 , and activity in the hippocampus also predicts accuracy of navigation ...
Sep 2, 2021 · One way to unify these disparate cross-species findings was the proposal that the hippocampus is responsible for encoding a “cognitive map” (Behrens et al., 2018; Buffalo, 2015; Howard et al., 2014; O’Keefe and Nadel, 1978), a network of associations that specifies how various features of the environment relate to one another. Such a map could be used to specify how the various disparate ...

Critical to Hasselmo’s particular version of cognitive map theory is the idea that the hippocampus and surrounding structures are a phase-coding mechanism, where the map-making activity of place and grid cells is integrated into maps of the environment at multiple spatial and temporal scales—that is, the hippocampus produces a series of cognitive maps, in Rescorla’s (2009) loose sense ...
