Neural Mechanisms of Attention

Abstract

This project achieved both of its stated goals. (1) The activity of single units was recorded while rats performed a divided attention task. The behavioral correlates of these units indicate three different classes: divided attention executive cells, selective attention cells, task cells. These indicate ways in which the frontal cortex is involved in attention, and provides information that can be incorporated into model systems. (2) New behavioral tasks were developed to measure reaction time in rats. These are similar to those used for testing humans, and provide animal models to assess the neuroanatomical, neuropharmacological, and electrophysiological processes involved in other kinds of attention. Keywords: Attention, Frontal cortex, Divided attention, Electrophysiological recording (unclassified).
