Rewarding effects of electrical stimulation of the insular cortex: decayed effectiveness after repeated tests and subsequent increase in vertical behavioral activity and conditioned place aversion after naloxone administration.

Abstract

The insular cortex has been associated with various aversive and rewarding sensory, regulatory, and learning processes. The objective of this study was to examine the characteristics of the reinforcement induced by electrical stimulation of this brain area in rats. Results obtained confirm that electrical stimulation of the insular cortex may induce… (More)
