Cholinergic and GABAergic innervation of the hippocampus plays an important role in
human memory function and rat spatial navigation. Drugs which block acetylcholine …

The theta rhythm appears in the rat hippocampal electroencephalogram during exploration
and shows phase locking to stimulus acquisition. Lesions that block theta rhythm impair …

Place cells in hippocampal area CA1 may receive positional information from the
intrahippocampal associative network in area CA3 or directly from the entorhinal cortex. To …

To examine how hippocampal neurons respond to a mismatch between retrieved and actual
experience, we trained rats to find a hidden platform at a particular location in an annular …

Some neurons encode information about the orientation or position of an animal, and can
maintain their response properties in the absence of visual input. Examples include head …

The goal of this paper is to propose a model of the hippocampal system that reconciles the
presence of neurons that look like “place cells” with the implication of the hippocampus (Hs) …

The interplay between principal cells and interneurons plays an important role in timing the
activity of individual cells. We investigated the influence of single hippocampal CA1 …

Single-neuron recording studies have demonstrated the existence of neurons in the
hippocampus which appear to encode information about the place where a rat is located …

There is a good deal of evidence that in the rodent, an internal model of the external world is
encoded by hippocampal pyramidal cells, called 'place cells'. During free exploration, the …

The firing of hippocampal principal cells in freely running rats exhibits a progressive phase
retardation as the animal passes through a cell's “place” field. This “phase precession” is …
