[Use of the microelectrode method for differentiation of white matter from thalamic nuclei during stereotaxic procedures].
Two hundred and three neurograms were recorded from the ventrolateral and reticular nuclei of the thalamus in 29 patients. Pulsed neuron activity was encountered in 116 cases. Reactions to motor tests were recorded from 26 neurons. The authors constructed maps of the location of the cerebral areas studied in relation to the main intracerebral guiding points. A large number of cells (44%) with rhythmic pulsed discharges with a frequency of 3-7 Hz were found in patients with parkinsonism and double athetosis. A great variability of background and induced activity of the thalamic nuclei under similar conditions of study was revealed.
