Peripheral thermal stimulation and thermoregulatory behavior

When thermal reinforcement was continuously available in a cold environment, 5 female Sprague-Dawley rats adjusted duration of reinforcement to obtain heat for a briefer interval as thermal intensity increased. A power function adequately described the relation between thermal intensity and the behavioral adjustment of thermal burst duration. Hypothalamic temperature varied within the narrow range of 1- C, regardless of the intensity of the thermal stimulation. Accurate assessment of the magnitude of peripheral sensory stimulation is a significant factor in behavioral thermoregulation. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
