A Comparison of Single Unit Activity in Primate Caudate Nucleus and Putamen in a Sensory Cued Motor Task
The behavioral correlates of single unit activity in the putamen and caudate nucleus were compared in primates. Single unit neuronal activity was recorded during the performance of a sensory cued reaching task. Units in the putamen were more often modulated with motor events than units in the caudate nucleus. The latter had many more units with anticipatory responses to sensory events of the task and more responses to sensory cues. It is suggested that the putamen plays a more important role in movement regulation than the caudate nucleus and that the caudate nucleus has a role in switching behavioral states.
