Competition between lever-pressing behavior and thermoregulatory behavior on exposure to heat in intracranial self-stimulating rats.

To investigate the relationship between the thermoregulatory system and the brain-reward system, we examined effects of heat exposure and tail amputation on lever-pressing behavior in intracranial self-stimulating rats. Rats that continuously pressed a lever voluntarily for 1 hour at an ambient temperature (Ta) of 22 degrees C interrupted lever pressing and… CONTINUE READING
