Currents That Set The Excitability Of Enteric Neurons And Their Roles At Cell And Organ Levels

Abstract

The intestine is subject to a number of disorders of its normal control by nerves, including diarrhoea, constipation and slow transit disorders. Chronic and debilitating derangement of intestinal function occurs in irritable bowel syndrome, which affects around 10-15% of people in our community, about 1% at any one time. Irritable bowel syndrome can persist for many years, and there is no adequate therapy. For some patients no medication gives relief, and for most the relief is minimal. The reflexes in the intestine that control its movements and secretion depend for their initiation on a special type of neuron, known as the intrinsic primary afferent neuron. These neurons have properties th..
