these findings lead us to conclude that the intramural grp neurons might play an important role in the regulation of gastrin as well as somatostatin secretion and that somatostatin secretion may be controlled not only by a cholinergic inhibitory neuron but also by a noncholinergic , e.g. , peptidergic stimulatory neuron , both of which may be regulated through preganglionic vagal fibers via nicotinic receptors .
