Ovariectomized rats were implanted with 23 gauge stainless steel cannulae in the ventrolateral midbrain central gray. Twelve sexually active rats were estrone-primed and infused with saline and 50 ng luteinizing hormone-releasing hormone (LHRH) in counterbalanced order. Infusion of luteinizing hormone-releasing hormone significantly enhanced the lordotic(More)
The techniques of microelectrophoresis and antidromic identification have been utilized in the female rat anesthetized with urethane to localize the tuberoinfundibular neurons and to determine their pharmacological sensitivity to dopamine (DA), norepinephrine (NE) and glutamate (GLUT). Extracellular recordings were made of 149 single units in the arcuate(More)
Lordotic behavior of ovariectomized estrone-primed rats was measured after infusions of luteinizing hormone-releasing hormone (LHRH), thyrotropin (TRH) or saline into the ventrolateral midbrain central gray (VL-MCG), or after LHRH or saline infusions into a lateral control site, the dorsolateral reticular formation (DL-RF). Infusion of LHRH, but not TRH,(More)
Lordotic behavior and LH release were measured in ovariectomized rats after radiofrequency lesions of the midbrain central gray (MCG), interpeduncular nucleus (IPN), mammillary bodies (MMM), stria medullaris (SM), or fasciculus retroflexus (FR), areas which are reported to contain immunoactive luteinizing hormone-releasing hormone (LHRH), a hypothalamic(More)
