Enteric viscerofugal neurons are mechanosensory interneurons that form the afferent limb of intestino-intestinal reflexes involving prevertebral sympathetic neurons. Fast synaptic inputs to viscerofugal neurons arise from other enteric neurons, but their sources are unknown. We aimed to describe the origins of synaptic inputs to viscerofugal neurons by mapping the locations of their cell bodies within the myenteric plexus. Read More

In vitro anterograde tracing of axons in mesenteric nerve trunks using biotinamide in combination with immunohistochemical labelling was used to characterize the extrinsic nerve projections in the myenteric plexus of the mouse jejunum. Anterogradely-labelled spinal sensory fibres innervating the enteric nervous system were identified by their immunoreactivity for calcitonin gene-related peptide (CGRP), while sympathetic noradrenergic fibres were detected with tyrosine hydroxylase (TH), using confocal microscopy. The presence of these markers has been previously described in the spinal sensory and sympathetic fibres. Read More

The spontaneous colonic migrating motor complex (CMMC) is a cyclical contractile and electrical event that is the primary motor pattern underlying fecal pellet propulsion along the murine colon. We have combined Ca(2+) imaging with immunohistochemistry to determine the role of different classes of myenteric neurons during the CMMC. Between CMMCs, myenteric neurons usually displayed ongoing but uncoordinated activity. Read More

Intracellular recordings were made from myenteric neurons of the guinea-pig distal colon to determine their electrical behaviour in response to intracellular current injection and stimulation of synaptic inputs. The recording microelectrode contained the intracellular marker biocytin, which was injected into impaled neurons so that electrophysiology, shape and immunohistochemistry could be correlated. Myenteric neurons in the distal colon were divided into four morphological groups based on their shapes and projections. Read More
