Abstract
Simultaneous recording of the ventricular CSF [cerebrospinal fluid] pressure and the thalamic tissue pressure was carried out on 7 Parkinsonian patients during thalamotomy. An ecg was taken as a reference point for timing studies. The ventricular CSF pressure wave preceded the thalamic pressure by 13 msec. on the average. The duration of the ventricular pressure wave was shorter than that of the thalamic pressure wave. The arterial CSF pressure wave originates from the large arteries at the base of the brain. These findings argue strongly against the theory that the choroid plexus causes this pulsation.
