Cerebral Heterostimulation in a Monkey Colony.
In an established colony a subordinate monkey repeatedly pr essed a lever which stimulated the caudate nucleus of the boss monkey by radio and inhibited his aggressive behavior. In other experiments, timed stimulations of the posteroventral nucleus of the thalamus of the boss monkey, paired with a tone, increased his aggressiveness and established conditioned escape responses of the whole group. Both types of experiments may be useful in neurophysiological and pharmacological investigations.
