Gradual decay of circadian drinking organization following lesions of the suprachiasmatic nuclei in primates.
The circadian organization of squirrel monkey drinking behavior was examined in constant illumination following lesions which totally destroyed the suprachiasmatic nuclei. Although these lesions eventually led to a severe disruption in the temporal organization of drinking behavior, a statistically significant circadian pattern of drinking was observed in each monkey for at least 4-6 weeks after lesioning.
