NEUROSECRETORY PHENOMENON OF THE PARAVENTRICULAR NUCLEUS IN A SENILE WOMAN

Adrenalectomy potentiates noradrenergic suppression of GABAergic transmission in parvocellular neurosecretory neurons of hypothalamic paraventricular nucleus.

Glucocorticoids are known to regulate both the noradrenergic and GABAergic inputs to the paraventricular nucleus (PVN). However, little is known about the effects of glucocorticoids on the interaction of these two input systems. Here we examined the effects of bilateral adrenalectomy (ADX) on the noradrenergic modulation of GABAergic transmission in the type II PVN neurons labeled with a retrog...

Paraventricular Nucleus Neurosecretory Neurons of Hypothalamic of GABAergic Transmission in Parvocellular Adrenalectomy Potentiates Noradrenergic Suppression

A slow transient potassium current expressed in a subset of neurosecretory neurons of the hypothalamic paraventricular nucleus.

Type I putative magnocellular neurosecretory cells of the hypothalamic paraventricular nucleus (PVN) express a prominent transient outward rectification generated by an A-type potassium current. Described here is a slow transient outward current that alters cell excitability and firing frequency in a subset of type I PVN neurons (38%). Unlike most of the type I neurons (62%), the transient outw...

Afferent renal inputs to paraventricular nucleus vasopressin and oxytocin neurosecretory neurons.

Extracellular single-unit recording experiments were done in pentobarbital sodium-anesthetized rats to investigate the effects of electrical stimulation of afferent renal nerves (ARN) and renal vein (RVO) or artery (RAO) occlusion on the discharge rate of putative arginine vasopressin (AVP) and oxytocin (Oxy) neurons in the paraventricular nucleus of the hypothalamus (PVH). PVH neurons antidrom...

a swot analysis of the english program of a bilingual school in iran

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
