title: The central effect of noradrenaline on thermoregulation in the neonatal guinea pig.
abstract: Noradrenaline (10 microgram) injected into the lateral cerebral ventricle of guinea pigs aged 2 to 12 days produced a rapid increase in oxygen consumption and in colonic temperature at an ambient temperature of 30 degrees C. The increase was most pronounced in the youngest animals and decreased with advancing age, but was still significant at 12 days of age. Species differences and the role of ambient temperature in the responses are discussed.
