摘要：

In awake immobilized cats stimulation of nonspecific thalamic nuclei (NCM, DM [nucleus centralis medialis and nucleus dorsalis medialis]) elicited evoked potentials in the head of the caudate nucleus (CN). The evoked potentials (EP) in the ventral part of CN were opposite in sign to those recorded in the dorsal region of CN. The points of polarity reversal were grouped in the lower third of CN. Peripheral sensory stimuli (somatic and visual) evoked potentials with a 20 ms latency. These evoked potentials changed their polarity in the same region as the thalamic evoked responses. Visual and somatic responding areas overlapped widely. The advantage of bipolar recordings for better localization was discussed.
