[Characteristics of cortical representation of the components of the gastroduodenal complex and role of the vagus nerve in the regulation of visceral afferentation].
Evoked potentials were registered at the cortex of both hemispheres of the brain during electrical stimulation of the body of the stomach, pylorus and duodenum pre and post bilateral vagotomy. It has been demonstrated that duodenum is represented at the cortex more widely in comparison with other parts of the gastroduodenal complex. Bilateral vagotomy increases amplitude of the evoked potentials, more substantially at the right hemisphere, that may be connected with enhancement of excitability of the irritating structure by exclusion of the efferent influence of vagal nerves, which take part in the regulation of visceral afferentation at the level of end organ nervous system.
