Restriction of Food Intake by Dorsomedial Hypothalamus
… profile leptin responsive neurons in the hypothalamus and brain stem. In addition to identifying several known leptin responsive populations, we found that neurons in Dorsomedial Hypothalamus (DMH) expressing GSBS are activated in ob/ob mice and suppressed by leptin treatment. Because ob …

The Role of Sonic Hedgehog in the Hypothalamus
ABSTRACT THE REQUIREMENT OF SONIC HEDGEHOG IN THE HYPOTHALAMUS Solsire E. Zevallos Douglas J. Epstein Sonic hedgehog (Shh) is a morphogen secreted during early development that is required for the formation of the ventral neural tube, including the ventral forebrain. The prechordal source of Shh …

Neural Stem / Progenitor Cells in the Adult Mouse Hypothalamus
… population of neural stem cells resides in the hypothalamus, more specifically in the ependymal lining of the third ventricle. In this thesis, I tested the hypothesis that stem cells exist in defined regions of the adult mouse hypothalamus. My work confirms the presence of stem / progenitor …

Hypoglycemia-induced changes in glucose metabolism in the hypothalamus
… (3), but changes occurring in the ventromedial hypothalamus (VMH), a brain region that is responsible for initiating the counterregulatory response to hypoglycemia (4) is the most promising target. In the following studies, we utilized metabolomic (Chapter 2), transcriptomic (Chapter 3), and …

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 states, …

In vivo Strukturveränderungen des Hypothalamus bei uni- und bipolaren affektiven Störungen
Als Kopf der Hypothalamus-Hypophysen-Nebennierenrinden-Achse spielt der Hypothalamus eine Schlüsselrolle für die depressive Symptomatik und bei pathogenetischen Modellen affektiver Störungen. Für nahezu alle Ebenen dieser Hormonachse lassen sich Funktions- und Strukturveränderungen, insbesondere …

The Effects of Progesterone on Extracellular Serotonin Levels in Rat Hypothalamus
… serotonin were monitored in the ventromedial hypothalamus (VMN), midbrain central grey (MCG) and medical preoptic area (POA) using microdialysis. Rats primed with estradiol benzoate (5 μg) were anesthetized with choral hydrate (400 mg/kg, i.p.). Samples were collected at 20 minute intervals. …

Altered Fuel Supply and Utilization in the Hypothalamus Following Recurrent Hypoglycemia
These findings indicate that local substrate concentrations in the VMH are altered by RH and are affected by glycogen availability and noradrenergic activity. The changes in local energy supply contribute to the impaired CRR seen in RH, supporting a role for altered metabolism in HAAF.

Role of the ventromedial hypothalamus in control of innate defensive behaviours
… controlling these behaviours. Ventromedial hypothalamus (VMH) is a key brain region for controlling responses to predators; it has been shown that inactivating the VMH can reduce defensive behaviours. Interestingly, activating the VMH output neurons (SF1+ cells) can produce a variety of …

Localization of Luteinizing Hormone-Releasing Hormone (LHRH) in the Hypothalamus of Fetal Bovine
… by Gonadotropin Releasing Hormone (GnRH) in the hypothalamus. Various analogs ofGnRH have been identified. Localization of these hormones is the first step in discovering the individual function of each analog. Immunohistochemistry and confocal microscopy were used to localize Luteinizing Hormone …

Hormone Regulation of NPY Neuron Activity in the Arcuate Nucleus of the Hypothalamus
… neurons in the arcuate nucleus of the hypothalamus are part of a neuroendocrine feedback loop that regulates feeding behavior and glucose homeostasis. NPY neurons sense peripheral signals of energy stores, including the hormones leptin, insulin, and ghrelin, and integrate those signals …

Altered GABA ergic system in the posterior hypothalamus of the spontaneously hypertensive rat
… GABAergic inhibitory mechanism in the posterior hypothalamus (PH) contributes to modulating cardiovascular activity. Blockade of GABA receptors on neurons in this area elicits an increase in sympathetic discharge, arterial pressure and heart rate. It has been proposed that a deficit in this …

Neurochemical Mechanisms in the Hypothalamus and Attenuation of Compensatory Hormone Responses to Recurrent Hypoglycemia
… noradrenergic neurotransmitter systems in the hypothalamus are activated to a decrease in ambient glucose, and their responsiveness is preserved after recurrent daily hypoglycemic episodes on three consecutive days. From the present work it became evident that the observed increase in liver …
