Variation in postpartum maternal care programs the development of neuroendocrine and mesolimbic dopamine pathways in female offspring
… critical for maternal behavior such as the medial preoptic area of the hypothalamus. The first series of experiments within this thesis demonstrates that these neuroendocrine differences in ERalpha-immunoreactivity and mRNA emerge in offspring during the postnatal period (postnatal days …

Opioid induction of Fos in the female rat brain : modulation by ovarian hormones
… was analyzed in the lateral septum, medial preoptic area, ventromedial hypothalamus, medial amygdala, and mesencephalic central gray. The present study found that Fos immunoreactivity was induced differentially by the opioid agonists within the different brain regions, and the …

Estrogen Signaling in the Ventromedial Hypothalamus Modulates Adipose Tissue Metabolic Adaptation
… in the ventrolateral region of the ventromedial hypothalamus (vlVMH), a sex-dimorphic structure that directly modulates brown adipose tissue (BAT) thermogenesis. We previously showed that an ERαvlVMH-originated neural circuit responds to changes in ambient temperature and nutritional …

Opiate Regulation of Lordosis: Neurochemical Evaluation of the Role of Opiate-Serotonergic Interactions
… facilitation of behavior by progesterone. The medial preoptic area (POA) was found to be important in the actions of naltrexone. The role of serotonergic systems in the opiate regulation of lordosis was examined. Lesions of hypothalamic serotonergic terminals blocked the inhibition of behavior …

Maternal Behavior in the Rat: Neuroendocrine and Neuroanatomical Substrates
<p>A pathway connecting the preoptic region and the ventral midbrain regulates the performance of maternal behavior by female rats. There Is also evidence that the facilitatory action of estrogen on maternal behavior is mediated via estrogen target cells In the medial preoptic region. Neither the …

An integrative analysis of the multi- and transgenerational effects of endocrine-disrupting chemicals on behavior and neurobiology
… the expression of candidate genes in the medial preoptic area (POA) and ventromedial nucleus (VMN) of the hypothalamus. These regions are both hormone-sensitive and involved in the regulation of reproductive behaviors. These results did not parallel our behavioral findings from the …

Mapping the substrate for brain stimulation reward : new approaches to an old problem
… effect produced by electrical stimulation of the medial forebrain bundle (MFB). This objective was addressed by combining immunohistochemical, lesion, and behavioral methods. Immunohistochemical staining of the immediate early gene product, Fos, was used to visualize neurons activated by rewarding …

Identification of central circuitry components mediating anorexigenic properties of oxytocin
… only the nucleus accumbens and ventral tegmental area of the mesolimbic system, and the brainstem’s dorsal vagal complex, have been directly implicated in relaying OT-induced hypophagia. Thus, the overarching goal of this thesis was to examine which discrete components of circuitry expressing the …

Characterization Of Neuronal Groups Regulating Sexual And Agonistic Behavior In Male Chicken (Gallus Gallus)
… identified by mapping Fos expression. The ventromedial subnucleus of medial portion of bed nucleus of the stria teriminalis (BSTM2) was specifically activated by male courtship behavior. The medial preoptic nucleus (POM) and lateral septum (SL) were associated with both sexual and agonistic …
