Local network regulation of orexin neurons in the lateral hypothalamus.
Obesity and inadequate sleep are among the most common causes of health problems in modern society. Thus, the discovery that orexin (hypocretin) neurons play a pivotal role in sleep/wake regulation, energy balance, and consummatory behaviors has sparked immense interest in understanding the regulatory mechanisms of these neurons. The local network consisting of neurons and astrocytes within the...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولOrexin a preferentially excites glucose-sensitive neurons in the lateral hypothalamus of the rat in vitro.
Falls in blood glucose induce hunger and initiate feeding. The lateral hypothalamic area (LHA) contains glucose-sensitive neurons (GSNs) and orexin neurons, both of which are stimulated by falling blood glucose and are implicated in hypoglycemia-induced feeding. We combined intracellular electrophysiological recording with fluorescein labeling of GSNs to determine their neuroanatomic and functi...
متن کاملOrexin-driven GAD65 network of the lateral hypothalamus sets physical activity in mice.
Damage to the lateral hypothalamus (LH) causes profound physical inactivity in mammals. Several molecularly distinct types of LH neurons have been identified, including orexin cells and glutamic acid decarboxylase 65 (GAD65) cells, but their interplay in orchestrating physical activity is not fully understood. Here, using optogenetic circuit analysis and cell type-specific deep-brain recordings...
متن کاملUrocortin in the lateral septal area modulates feeding induced by orexin A in the lateral hypothalamus.
The intermediate portion of the lateral septum (LSi) contains high levels of urocortin (UCN) peptide and type 2 corticotropin-releasing hormone (CRH) receptor (CRHR2) and has anatomic and functional connections with the lateral hypothalamus (LH). We tested the effect of UCN in the LSi on feeding. Injection of 10 or 30 pmol UCN into LSi significantly decreased feeding in food-deprived rats for 2...
