Electrical activity of the stomach: nervous control.
The role of the extramural vagus nerves in the modulation of gastric electrical activity and the myoelectrical complex (MEC) was studied by electrical stimulation of the nerve of Latarjet. As a consequence of the interruption of vagal impulses for five months by bilateral transthoracic vagotomy, the intramural nervous system began to perform as an organiser and modulator of the disorganised gastric electrical activity. The modulating role of the intramural nervous system was also demonstrated by stimulating the transmural electrical system, using parameters such as spike-firing and duration of stimulation of the MEC, and by blocking the adrenergic receptors.
