Abstract
The effects of changes in body core temperature (T(B)) upon the frequency of chemosensory discharges (f(x)) from one carotid nerve were studied in pentobarbitone anesthetized cats. Raising T(B) from 35 to 40-degrees-C increased f(x) in some cats, an effect more commonly seen after contralateral carotid neurotomy. In other animals, the simultaneously increased alveolar ventilation counteracted the above effect. A multiple correlation analysis of global data showed predicted increases in f(x) in response to raising T(B) at different CO2 levels.
