Corticotropin-releasing factor: effects on the sympathetic nervous system and oxygen consumption

Corticotropin-releasing factor administered intracerebroventricularly produces prolonged elevation of plasma concentration of epinephrine, norepinephrine and glucose. These hormonal changes are associated with an increase in motor activity and oxygen consumption. No change in body temperature is observed. CRF produces changes in animal physiology that are similar to those observed in response to stress.
