Caudate unit activity in freely moving cats: effects of phasic auditory and visual stimuli.
Quantitative analyses of the single unit responses to sensory stimuli were made in caudate nucleus neurons in the unanesthetized freely moving cat. Over half of the cells were responsive to repetitive presentation of simple sensory stimuli. Typically, neurons gave similar responses to both auditory (click) and visual (flash) stimuli. This study confirms previous reports of the polysensory response characteristics of caudate nucleus neurons, and extends these observations to the freely moving animal.
