To investigate the direct effects of endogenous pyrogen (EP) and prostaglandin E2 (PGE2) on the activity of neurons in the preoptic and anterior hypothalamic (PO-AH) region, single-unit activity was recorded from brain tissue slices prepared from the PO-AH region of guinea pigs. When EP was applied into the perfusate 18% of warm-responsive neurons decreased(More)
Ethanol is a deleterious agent that causes various kinds of neuronal damage to both the developing and adult brain. Recent research on alcoholism implicates impaired function of neural stem cell (NSC) in the pathogenesis of ethanol-induced brain dysfunction. We previously reported that the differentiation of NSCs into neurons was significantly influenced by(More)
The involvement of the ventromedial hypothalamus (VMH) in thermoregulatory responses, which include heat production and heat loss responses, was investigated by the method of electrical stimulation. Electrical stimulation of the VMH caused a rise in rectal temperature, accompanied by the enhancement of heat production: O2 consumption and shivering. In(More)
The central nervous structures involved in febrile responses were investigated in conscious rats by means of the 2-deoxy-D-[14C]glucose autoradiographic technique. An intravenous injection of endogenous pyrogen prepared from rabbit white blood cells induced a significant rise in the rectal temperature of rats accompanied by a decrease in the skin(More)
The central nervous structures involved in behavioral thermoregulatory responses during cold exposure were investigated in conscious rats by means of the 2-deoxy-D-[14C]glucose ([14C]-DG) autoradiographic technique. According to autoradiographs, many brain regions with significant increases or decreases in [14C]-DG incorporation were observed during(More)
