Properties and distribution of auditory neurons in the dorsolateral prefrontal cortex of the alert monkey.

In alert monkeys, some prefrontal neurons located in the superior dorsolateral area were activated to acoustic stimuli delivered in a restricted range of directions with respect to the animal's head. The effective direction was usually contralateral to the animal. The function of the auditory neurons in connection to that of the visual ones, which are commonly found in the prefrontal cortex, is discussed.
