Abstract

1. 1|In rats the irreversible disturbance of thermoregulation induced by capsaicin is characterized as follows: (a) temperature selection and regulation of body temperature are severely impaired at warm Ta but not below 30°C: (b) the heat-loss response of tail vasodilatation sets in at an elevated threshold of skin and body temperatures and its effectiveness is inhibited by peculiar fluctuations. Temperature threshold for grooming is shifted even further. 2. 2|Intra-arterial capsaicin injection excited and desensitized one spurious warm unit but had no effect on two cold units of the rabbit ear. 3. 3|The differential influence of capsaicin on thermoregulatory responses provides evidence for the multiple thermostat theory.
