Galanin neurons in the medial preoptic area govern parental behaviour
Mice display robust, stereotyped behaviours towards pups: virgin males typically attack pups, whereas virgin females and sexually experiencedmales and females display parental care. Here we show that virginmales genetically impaired in vomeronasal sensing do not attack pups and are parental. Furthermore, we uncover a subset of galanin-expressing neurons in the medial preoptic area (MPOA) that a...
متن کاملProdynorphin- and substance P-containing neurons project to the medial preoptic area in the male Syrian hamster brain.
To determine if substance P- or prodynorphin-containing neurons of the medial nucleus of the amygdala and medial bed nucleus of the stria terminalis send projections to the medial preoptic area in the male Syrian hamster, we placed a fluorescent retrograde tract tracer (either Fluoro-gold, or rhodamine- or fluorescein-impregnated latex microspheres) into the medial preoptic area. Five to seven ...
متن کاملAlterations of medial preoptic area neurons following pregnancy and pregnancy-like steroidal treatment in the rat.
There is a marked increase in the maternal behavior displayed by a female rat following pregnancy-due primarily to exposure to the gonadal hormones progesterone and estradiol (P and E(2), respectively). We examined Golgi-Cox silver-stained, Vibratome-sectioned neurons visualized and traced using computerized microscopy and image analysis. In Part One, we examined the hormonal-neural concomitant...
متن کاملsiRNA silencing of estrogen receptor-α expression specifically in medial preoptic area neurons abolishes maternal care in female mice.
The medial preoptic area has been shown to be intricately involved in many behaviors, including locomotion, sexual behavior, maternal care, and aggression. The gene encoding estrogen receptor-α (ERα) protein is expressed in preoptic area neurons, and a very dense immunoreactive field of ERα is found in the preoptic region. ERα knockout animals show deficits in maternal care and sexual behavior ...
متن کاملProlactin action in the medial preoptic area is necessary for postpartum maternal nursing behavior.
Pregnancy hormones, such as prolactin, sensitize neural circuits controlling parental interactions to induce timely activation of maternal behaviors immediately after parturition. While the medial preoptic area (MPOA) is known to be critical for maternal behavior, the specific role of prolactin in this brain region has remained elusive. Here, we evaluated the role of prolactin action in the MPO...
