Abstract
This article presents behavioral and electrophysiological evidence that one of ethanol's major effects in the brain is a marked impairment in spatial cognitive processing. The behavioral evidence indicates that ethanol produces deficits on tasks requiring spatial memory and spatial learning. The electrophysiological evidence indicates that ethanol degrades the spatial specificity of hippocampal place cells. Togther, these results suggest a neurophysiological basis for an animal's impaired performance on spatial navigation tasks while intoxicated. Such impaired performance in spatial cognitive processing could well be a factor in impaired performance by intoxicated humans on tasks requiring spatial navigation, such as automobile driving.
