Electrophysiologically, it has also been shown that there is a functionally specific correlation between the PVN and medullary neurons that are related to the gastric function. Moreover, it was observed that activation of oxytocinergic neurons in the PVN caused by electrical stimulation or OXT application strongly influences gastric acid secretion. The inhibitory response in acid secretion is substantially blocked by vagotomy or by an anticholinergic agent applied onto the medullary gastric neuron and the peripheral site. Since OXT has been shown to be synthesized in the PVN magnocellular nucleus and act locally within the nucleus to control its activity, these findings suggest that the activation of oxytocinergic neurons due to intrinsic OXT within the PVN participates in the control of gastric acid secretion with a change in vagal activity, and that a specific nucleus localized in the medulla oblongata is involved in this system as a relaying mechanism.}, pages = {89--96}, title = {Gastric Acid Secretion Controlled by the Oxytocinergic Neuron in the Hypothalamic Paraventricular Nucleus}, volume = {40}, year = {1992} }
