Topography of 'bilateral-movement-evoked' thalamic cellular activity found during diencephalic recording

With the aid of a computer graphic technique, data gathered from exploratory diencephalic recording in 130 stereotactic procedures are presented to show the topography of 'bilateral-movement-evoked' thalamic cellular activity. Thalamic cells responding to bilateral voluntary extremity movement were found to occupy a thalamic zone rostral to the zone for 'muscle'- and 'joint'-evoked thalamic cellular activity.
