The idea that females of most mammalian species have lost the capacity for oocyte production at birth has been challenged recently by the finding that juvenile and adult mouse ovaries possess mitotically active germ cells. However, the existence of female germline stem cells (FGSCs) in postnatal mammalian ovaries still remains a controversial issue among(More)
Peripheral cholecystokinin (CCK) reduces food intake and triggers the secretion of both oxytocin and corticotropin-releasing hormone. These responses are partially initiated by activation of receptors in the peripheral endings of the vagus nerve. However, in vivo studies showing that after vagotomy systemic CCK induces fos activation of neurons in the area(More)
The area postrema (AP) has been repeatedly implicated in cardiovascular regulation. Microinjection and single unit recording studies in vivo have suggested specific actions for angiotensin II (ANG) and glutamate (GLU) in controlling the excitability of AP neurons. The present study was therefore designed to examine the responsiveness of AP neurons to bath(More)
The area postrema (AP) is a circumventricular organ located on the dorsal surface of the medulla. Substantial evidence suggests that the AP is an important site involved in cardiovascular regulation. Arginine vasopressin (AVP) is thought to act at the AP to increase the sensitivity of the baroreceptor reflex. We have therefore examined the effects of AVP on(More)
