Pregnant rats were injected with 4 mg of testosterone propionate (TP) from days 15 to 22 of pregnancy or a single dose of 4 mg TP on day 17 or 21 of pregnancy. Female offspring treated with TP or the vehicle prenatally were sacrificed at 90 days of age. The volume of the cluster of intensely stained neurons in the medial preoptic area, the "sexually dimorphic nucleus of the preoptic area" (SDN-...

Progenitor cells in the medial ganglionic eminence (MGE) and preoptic area (PoA) give rise to GABAergic inhibitory interneurons that are distributed in the forebrain, largely in the cortex, hippocampus, and striatum. Two previous studies suggest that clonally related interneurons originating from individual MGE/PoA progenitors frequently form local clusters in the cortex. However, Mayer et al. ...

Thiamine deficiency and beriberi are prevalent in Cambodia, although most infants with nonspecific clinical symptoms of beriberi, including tachypnea, lack echocardiographic evidence diagnostic of the disease. Camphor activates transient receptor potential vanilloid 3 (TRPV3), a nonselective ion channel expressed in the medial preoptic nucleus of the hypothalamus and thought to be important for...
