[The effects of the electrical microstimulation of the areas of the location of different cell types in the caudate nucleus].
Effects of electrostimulation of the caudate nucleus in cats were studied in chronic experiments. Position of electrolytic lesions resulting from stimulation was examined histologically with respect to the surrounding cell type. Stimulation of the caudate nucleus zones with cells responding to sensory stimuli induced cat's movement and corresponding lesions were situated around striosomes among large cells with long axons. Stimulation of "silent" zones (where we failed to record any neuronal activity) did not modify cat's behaviour, corresponding lesions were found inside striosomes in clusters of small and medium-size cells. Results obtained from this study confirm the previous conclusion that neurons which activity was recorded extracellularly in the caudate nucleus belong to large long-axon cells.
