A computational theory of the hippocampal cognitive map

J O'Keefe - Progress in brain research, 1990 - Elsevier
Evidence from single unit and lesion studies suggests that the hippocampal formation acts
as a spatial or cognitive map (O'Keefe and Nadel, 1978). In this chapter, I summarise some …

Ibotenate lesions of hippocampus and/or subiculum: dissociating components of allocentric spatial learning

RGM Morris, F Schenk, F Tweedie… - European Journal of …, 1990 - Wiley Online Library
This study examined the effects of ibotenic acid‐induced lesions of the hippocampus,

Long-term stability of the place-field activity of single units recorded from the dorsal hippocampus of freely behaving rats

LT Thompson, PJ Best - Brain research, 1990 - Elsevier
Over 90% of all spontaneously active hippocampal pyramidal cells in freely moving rats
signal the animal's spatial position by reliably changing their firing rate each time the animal …

Reversible inactivation of the medial septum differentially affects two forms of learning in rats

SJY Mizumori, GM Perez, MC Alvarado, CA Barnes… - Brain research, 1990 - Elsevier
The contribution of the medial septum to different aspects of spatial information processing

Spatial firing properties of hippocampal theta cells

JL Kubie, RU Muller, E Bostock - Journal of Neuroscience, 1990 - Soc Neuroscience
Previous studies have shown that complex-spike cells, the most common cell type recorded
in the hippocampus of freely moving rats, have the property of spatial firing--that is, a cell will …

Hippocampal complex spike cells do not change their place fields if the goal is moved within a cue controlled environment

A Speakman, J O'keefe - European Journal of Neuroscience, 1990 - Wiley Online Library
It has been shown that most hippocampal complex‐spike cells fire at specific locations in
relation to a set of controlled spatial cues and that they continue to fire in the appropriate …

Theoretical and neurophysiological analysis of the functions of the primate hippocampus in memory

ET Rolls - Cold Spring Harbor symposia on quantitative …, 1990 - symposium.cshlp.org

hippocampus, how these are related to the memory functions performed by the …

Behavioral correlates of theta-on and theta-off cells recorded from hippocampal formation of mature young and aged rats

SJY Mizumori, CA Barnes, BL McNaughton - Experimental brain research, 1990 - Springer
Most hippocampal formation single units in freely behaving rats fall into one of two
categories (Ranck 1973). The most obvious behavioral correlate of complex-spike (CS) cells …

Role of the hippocampus in temporal and spatial navigation: an adaptive neural network

NA Schmajuk - Behavioural Brain Research, 1990 - Elsevier
The hippocampus has been proposed to participate in either spatial or temporal mapping.
As an alternative to these seemingly conflicting views, we hypothesized that the …
