Abstract

Lesion of the anteroventral third-ventricle region (AV3VX) reduced saline consumption. Salt loading in AV3VX rats resulted in reduced but not completely abolished c- fos expression in the supraoptic and paraventricular nuclei. Intrinsic osmosensitivity of the magnocellular neurons, or input from other brain areas, such as the subfornical and median preoptic nuclei, may account for this residual c- fos expression. These regions showed c- fos expression following salt loading.

Fos-protein

Hypothalamus

Osmotic stimulus

Oxytocin

Vasopressin
