Abstract

Continuous recording of pulsatile cerebral impedance (PCI), heart rate (HR) and oxygen consumption (VO2) in rabbits aged 21 to 54 days demonstrated in response to transfer from an ambient temperature (Ta) of 25°C to Ta 10°C an increase in the amplitude of PCI in 11 out of 16, in HR in 15 out of 16, and in VO2 in all of the 16 observations. Indices combining the changes in PCI and HR indicated an increase in cerebral blood flow in 15 out of 16 cold exposures.
