title: Distribution of evoked potentials on stimulation of the human pulvinar.
abstract: The distribution of the evoked cortical potentials recorded during stereotactic pulvinectomy is analyzed. The evoked cortical potential shows maximal amplitude in the precentral area, with decreasing amplitude in the parietal and anterior temporal area, and minimal amplitude in the occipital area. The pulvinar has been histologically considered to have dense connections with the parietal lobe and no connection with the frontal lobe. However, our results suggest that the pulvinar has a dense functional connection with the frontal cortex, through which the pulvinar plays a role in motor function.
