What Is a Cognitive Map? Organizing Knowledge for Flexible Behavior
Timothy E.J. Behrens,Timothy E.J. Behrens,Timothy H. Muller,James C.R. Whittington,Shirley Mark,Alon B. Baram,Kimberly L. Stachenfeld,Zeb Kurth-Nelson +7 more
TL;DR: Experimental evidence and theoretical frameworks that point to principles unifying how to learn and use abstract, generalizable knowledge are reviewed and it is suggested that map-like representations observed in a spatial context may be an instance of general coding mechanisms capable of organizing knowledge of all kinds.
Journal ArticleDOI
The cognitive map in humans: spatial navigation and beyond
TL;DR: Recent studies indicate that the human hippocampus and entorhinal cortex support map-like spatial codes, and posterior brain regions such as parahippocampal and retrosplenial cortices provide critical inputs that allow cognitive maps to be anchored to fixed environmental landmarks.
Integration of visual motion and locomotion in mouse visual cortex
Aman B. Saleem,Aslı Ayaz,Kathryn J. Jeffery,Kenneth D. Harris,Kenneth D. Harris,Kenneth D. Harris,Matteo Carandini +6 more
TL;DR: In this article, the primary visual cortex (V1) carries signals related to visual speed, and its responses are also affected by run speed during navigation, and nearly half of the V1 neurons were reliably driven by combinations of visual speed and run speed.

Coherent encoding of subjective spatial position in visual cortex and hippocampus
Aman B. Saleem,Aman B. Saleem,Efthymia Diamanti,Efthymia Diamanti,Julien Fournier,Kenneth D. Harris,Matteo Carandini +6 more
TL;DR: It is concluded that visual responses in V1 are controlled by navigational signals, which are coherent with those encoded in hippocampus and reflect the animal’s subjective position.

The hippocampal engram maps experience but not place
Kazumasa Z. Tanaka,Hongshen He,Anupratap Tomar,Kazue Niisato,Arthur J Huang,Thomas J. McHugh +5 more
TL;DR: It is found that during memory encoding, only a fraction of CA1 place cells function as engram neurons, distinguished by firing repetitive bursts paced at the theta frequency, which demonstrate a dissociation of precise spatial coding and contextual indexing by distinct hippocampal ensembles and suggest that the hippocampal engram serves as an index of memory content.

The Hippocampus as a Cognitive Map
John O'Keefe,Lynn Nadel +1 more
TL;DR: The amnesic syndrome is presented as an extension of the theory to humans and the role of operators in the locale system is examined.
Journal ArticleDOI
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.
Journal ArticleDOI
Developments of a water-maze procedure for studying spatial learning in the rat
TL;DR: Developments of an open-field water-maze procedure in which rats learn to escape from opaque water onto a hidden platform are described, suggesting that they may lend themselves to a variety of behavioural investigations, including pharmacological work and studies of cerebral function.
Journal ArticleDOI
Place navigation impaired in rats with hippocampal lesions.
TL;DR: It is reported that, in addition to a spatial discrimination impairment, total hippocampal lesions also cause a profound and lasting placenavigational impairment that can be dissociated from correlated motor, motivational and reinforcement aspects of the procedure.
Journal ArticleDOI
Cognitive maps in rats and men
TL;DR: Most of the rat investigations, which I shall report, were carried out in the Berkeley laboratory, and a few, though a very few, were even carried out by me myself.
