[Changes in the flux frequency of the neuronal discharges of human subcortical brain structures related to the organization of motor acts].
16 Parkinsonian patients (6 females) with depth electrodes within striopallido-thalamic system implanted for diagnostic and therapeutic purposes, voluntarily participated in four psychological tests. Two groups of the pallidal and thalamic neuronal populations (response- and stimulus-related neuronal populations) were distinguished on the basis of evoked responses in the motor odd ball test. Response-related neurons were in turn separated into several subgroups according to their reactions in the delayed-response tasks. Some of these neuronal populations reacted preferentially to counting, some--to naming, some--to pressing button.
