title: Consummatory behavior and urine production after cerebroventricular injection of vasopressin and vasopressin antiserum.
abstract: Vasopressin, or vasopressin antiserum, was injected into a lateral cerebral ventricle of conscious rats. These rats were normally hydrated, cellular dehydrated (NaCl loading) or hypovolemic (polyethylene glycol model). Elevation or reduction of vasopressin in cerebrospinal fluid produced no consistent change in consummatory behavior, urine volume or sodium and potassium excretion. These results show vasopressin in cerebrospinal fluid not to be an absolute requirement for maintenance of hydration or for response to acute volume and osmotic stimuli.
