Cholinergic brain mechanisms and the hormonal regulation of female sexual behavior in the rat.
Cholinergic muscarinic stimulation of the medial preoptic area or the mesencephalic reticular formation with carbachol or bethanechol facilitated lordosis in ovariectomized female rats treated with estrogen. Adrenalectomy did not abolish the facilitative influence of cholinergic stimulation in the preoptic area. Implants of carbachol in the neocortex failed to increase lordosis.
