Abstract

Recent technological advances have led to an increased emphasis on understanding how separate anatomical systems interact to carry out basic computational functions associated with sensorimotor selection and control. In the first section of this paper we review evidence for three anatomical networks involved in selective attention. We then describe a simple neural network model that we have used to simulate aspects of the interaction between anterior and posterior attention networks. Finally, we focus upon the computational role of the brain's catecholamine neurotransmitter systems, and speculate on whether these systems may implement certain computational devices utilized within our neural network model.
