which causes a marked and long-lasting fall in body 

 temperature (85). A more significant interference 

 with temperature regulation in man has been ob- 

 served under psychopathological conditions. Schizo- 

 phrenic patients may show abnormally large and 

 irregular daily variations of body temperature (39), 

 probably occurring as a result of both inadequate 

 heat-loss control and heat-production activity. This 



abnormality may disappear after bilateral prefrontal 

 lobotomy (40). 



Sweating, Salivation and Piloerection 



As examples of centrally evoked thermoregulatory 

 effector responses, sweating, salivation and piloerec- 

 tion have been less studied than panting, cutaneous
