The mammalian hippocampal formation appears to play a major role in the generation of
internal representations of spatial relationships. In rats, this role is reflected in the spatially …

1. Neural activity in the monkey hippocampal formation (HF) was analyzed during a spatial
moving task in which the monkey was guided by auditory and visual cues and when stimuli …

Monkeys were given a series of problems to solve in which they had to learn whether to
approach a given visual stimulus and make repeated contact with it or to withdraw from the …

To determine how spatial scale is represented in the pyramidal cell population of the
hippocampus, we recorded neural activity at multiple longitudinal levels of this brain area …

Ensemble recordings of 73 to 148 rat hippocampal neurons were used to predict accurately
the animals' movement through their environment, which confirms that the hippocampus …

In the adult brain, space and orientation are represented by an elaborate hippocampal-
parahippocampal circuit consisting of head-direction cells, place cells, and grid cells. We …

Responses of cells in the dorsal hippocampus of rats to restraining tactile stimuli as a
function of spatial orientation suggest that the hippocampus provides the rest of the brain …

A long-standing conjecture in neuroscience is that aspects of cognition depend on the
brain's ability to self-generate sequential neuronal activity. We found that reliably and …

An animal's awareness of its location in space depends on the activity of place cells in the
hippocampus. How the brain encodes the spatial position of others has not yet been …

The correlated activity of rat hippocampal pyramidal cells during sleep reflects the activity of
those cells during earlier spatial exploration. Now the patterns of activity during sleep have …
