Nauta's (12) experiments in 1946 that showed insomnia after lesions of the preoptic region also supported the hypothesis of active hypnogenic neurons in the forebrain preoptic area.
Endogenous antipyretics attenuate fever by influencing the thermoregulatoty neurons in the preoptic region and anterior hypothalamus and in adjacent septal areas.
Practitioners know today that thermoregulatory neurons in the preoptic region and anterior hypothalamus (POAH) and in adjacent septal areas are influenced by endogenous pyrogens to produce fever and secrete antipyretic factors to attenuate fever (Boulant, 1997; Mackowiak & Boulant, 1996).
