Abstract
This chapter presents a study in which a monkey was trained for hand movement and vocalization, and cortical field potentials were recorded during the movement by a pair of electrodes implanted in the cerebral cortex in the monkey. The potentials were analyzed in connection with behavioral observations. The chapter argues that the specific response to information—i.e., to move or not to move, and to move willingly or reluctantly—is judged and decided on in the prefrontal cortex. It is also suggested that the limbic system is more significant in vocalization than in hand movements.
