[The distribution of orientation-selective neurons in the thalamic nuclei and striopallidal complex of the human brain].

The impulse activity of 177 neuronal populations analyzed in different nuclei of the thalamus and striopallidal complex during visual testing for orientation sensitivity in 9 parkinsonian patients, diagnosed and treated with the long-term intracerebral electrodes. Orientation-selective neurons related to visual perception constancy were revealed in centrum medianum, zona incerta and nucleus reticularis of the thalamus, nucleus caudatus, globus pallidus medialis. The comparative percentage and distribution of neurons with different properties in the thalamus and striopallidal nuclei were studied.
