Electrical stimulation in subfornical organ increases plasma vasopressin concentrations in the conscious rat
A. V. Ferguson and N. W. Kasting Electrical stimulation in the subfornical organ (SFO) of conscious freely moving rats was found to increase plasma vasopressin concentrations from control values of 1.43 +/- 0.32 to poststimulation values of 22.32 +/- 4.9 pg/ml (P less than 0.01).

Electrical stimulation in the subfornical organ (SFO) of conscious freely
moving rats was found to increase plasma vasopressin concentrations from
control values of 1.43 +/- 0.32 to poststimulation values of 22.32 +/- 4.9
pg/ml (P less than 0.01). Similar stimulation in immediately adjacent brain
regions including the medial septum and hippocampal commissure caused no
significant changes in plasma concentrations of this peptide hormone. These
data indicate that activation of SFO neurons in conscious rats causes
increased release of vasopressin from the posterior pituitary. Such data
corroborate previous electrophysiological findings demonstrating that in
anesthetized animals electrical stimulation in SFO results in increased
excitability of antidromically identified vasopressin-secreting neurons in
the supraoptic and paraventricular nuclei of the hypothalamus. |
