...Alicia M. Seltzer; Alfredo O. Donoso The relationship between GABA dynamics and LH release was studied on day 2 after subcutaneus estrogen implant in short-term ovariectomized rats. GABA accumulation, used as an index of GABA turnover, was determined in the medial preoptic nucleus (MPN), medial (MS...

...Jorge Larriva-Sahd In the rat, a new structural sex difference of the nervous system was found: the density of axodendritic synapses (ADS) is larger in the male central component of the medial preoptic nucleus (MPNc), as proven by quantitative electron microscopy. The study included 24 animals...

...Anthony E. Oro; Richard B. Simerly; Larry W. Swanson The central part of the medial preoptic nucleus (MPNc), the encapsulated part of the bed nucleus of the stria terminalis (BSTe), and the posterodorsal part of the medial nucleus of the amygdala (MeAp) are all thought to be involved in the neural...

...Oline K. Ronnekleiv; Martin J. Kelly The effects of discrete lesions of the suprachiasmatic and medial preoptic nucleus on luteinizing hormone-releasing hormone (LHRH) neurons of the female rat were examined. The lesions disrupted the estrous cycle and prevented the preovulatory surge...

... lesions were placed at four loci along the rostrocaudal extent of the suprachiasmatic region in regularly cycling female rats. Anovulatory persistent estrus occurred only when lesions were located either in the suprachiasmatic nucleus (SCN) or the medial preoptic nucleus (MPN), a small periventricular...

... included the suprachiasmatic nuclei (SCN) induced an anovulatory condition characterized by persistent vaginal cornification and polyfollicular ovaries (persistent estrus). Large or small lesions which included the medial preoptic nucleus (MPN), a small periventricular column of cells located immediately...
