Brain stimulation-induced changes of phonation in the squirrel monkey.

abstract：:In order to study neuronal information transfer from the striatum to the globus pallidus (GP) during voluntary movement, we recorded activity of electrophysiologically identified projection neurons in the putamen to the GP while the monkey was performing learned movement tasks. Two categories of putamen neurons were r...
