Experiments were performed to determine whether the suppression of prolactin (PRL) surges during restraint was accompanied by changes in the activity of tuberoinfundibular dopamine (TIDA) neurons in the median eminence. Animals were either ovariectom

Pharmacological studies have suggested that neurotransmitter activity impinging on steroid-concentrating cells can affect the steroid receptor system within those cells, modifying behavioral responses to the hormone. The present experiments revealed

gamma-Aminobutyric acid (GABA) neurones are present in the zona incerta (ZI) where other systems have been shown to influence gonadotrophin release. This report investigates the effect of GABA agents in the ZI on ovulation and luteinizing hormone (LH

The effects of dopamine (DA) on prolactin (PRL) secretion in anterior pituitary tissue from rats selected during various stages of the estrous cycle were analyzed under in vitro conditions. The results were examined in relation to plasma PRL, estradi

The functions of tuberoinfundibular dopaminergic (TIDA) neurons after long-term estradiol treatment were investigated in Fischer 344 (F344) rats which have high susceptibility to estradiol-induced prolactin (PRL)-secreting pituitary tumors. Dopamine

We have previously found that progesterone (P) augmented gonadotropin-releasing hormone (GnRH) mRNA levels in the hypothalamus of ovariectomized, estradiol-treated (OVX + E) prepubertal rats. In order to determine whether noradrenergic neurotransmiss

Previous studies have shown that POMC mRNA and peptide levels are increased in the medial basal hypothalamus (MBH) of the chronically castrated rat and are suppressed with sex steroid replacement. In a parallel time course, hypothalamic dopamine turn

We investigated the effect of ovariectomy (OVX) and subsequent estradiol benzoate (EB) treatment upon the N-methyl-D-aspartate (NMDA)-induced LH secretion in adult female rats. Furthermore, the release of LHRH, norepinephrine (NE), dopamine (DA), 5-h

Oxytocin (OT) neurotransmission in the brain has a facilitatory effect on sexual receptivity in rats. This effect of OT is dependent on priming by ovarian steroids, estrogen and progesterone. These steroids modulate OT binding in specific brain nucle

The purpose of the present investigation was to determine the effects of naloxone on LHRH and catecholamine release from preoptic area-medial basal hypothalamic (POA-MBH) fragments in vitro. Ovariectomized rats were treated with estradiol benzoate, f
