Immunohistochemical detection of c-Fos expression was used to identify gastric myenteric plexus neurons that receive excitatory input from vagal efferent neurons activated by electrical stimulation of the cervical vagi in anesthetized rats. Vagal stimulation-induced Fos expression increased with higher pulse frequency, so that with 16 Hz (rectangular pulses of 1 mA/0.5 ms for 30 min) approximately 30% and with 48 Hz 90% of all neurons near the lesser curvature were Fos positive. In sham…

Vagus nerve stimulation preferentially induces Fos expression in nitrergic neurons of rat esophagus

The present results showing that electrical stimulation of the vagus nerves induces a high proportion of Fos neurons with NOS-IR suggests the preferential activation of NOS neurons in the esophagus by vagal preganglionic efferents.

Acute cold exposure induces vagally mediated Fos expression in gastric myenteric neurons in conscious rats.

The results indicate that acute cold exposure activates cholinergic as well as nitrergic neurons in the gastric myenteric ganglia through vagal nicotinic pathways in conscious rats.

Intracisternal TRH analog induces Fos expression in gastric myenteric neurons and glia in conscious rats.

Results indicated that central vagal efferent stimulation by intracisternal RX-77368 activates gastric myenteric neurons as well as glial cells mainly through nicotinic ACh receptors in conscious rats.

Mucosal acid challenge activates nitrergic neurons in myenteric plexus of rat stomach.

It is concluded that gastric acid challenge concentration-dependently stimulates a subpopulation of nitrergic, but not cholinergic, myenteric plexus neurons, which may play a role in muscle relaxation, vasodilatation, and/or secretion.

Spatial organization of neurons in the dorsal motor nucleus of the vagus synapsing with intragastric cholinergic and nitric oxide/VIP neurons in the rat.

Depending on the location, microinjection of L-Glu into the DMV may stimulate intragastric myenteric cholinergic neurons or NO/VIP neurons to mediate gastric contraction and relaxation.

Vagal‐enteric interface: Vagal activation‐induced expression of c‐Fos and p‐CREB in neurons of the upper gastrointestinal tract and pancreas

The results demonstrate the suitability of this method to investigate magnitude and local distribution of vagal input to the enteric nervous system as well as specificity of its neurochemically coded pathways.

Fos expression in rat celiac ganglion: an index of the activation of postganglionic sympathetic nerves.

Fos expression in the CG may be a useful index to describe various levels of activation of its postganglionic sympathetic neurons in response to chemical, electrical, and reflexive stimulation.

It is revealed that brain-gut neurons regulating vagal outflow to the stomach/duodenum are sensitively responsive to insulin hypoglycemia.

Capsaicin‐sensitive extrinsic afferents are involved in acid‐induced activation of distinct myenteric neurons in the rat stomach

Challenge of the rat gastric mucosa with 0.5 mol L−1 HCl activates nitrergic neurons in the myenteric plexus as visualized by c‐Fos immunohistochemistry, leading to activation of presumably inhibitory motor neurons responsible for muscle relaxation.



Limited excitatory local effector function of gastric vagal afferent intraganglionic terminals in rats.

Given the many enteric neurons in close anatomic contact with IGLEs and the low proportion of Fos activated neurons after selective afferent stimulation, the results do not support a widespread excitatory local effector function ofIGLEs, however, inhibitory effects and/or weak excited synaptic inputs that do not engage Fos expression cannot be ruled out.

Electrophysiological identification of vagally innervated enteric neurons in guinea pig stomach.

The observations call into question the concept of enteric command neurons in favor of a divergent vagal input with widespread modulatory influences over gastric enteric neurotransmission.

Nuclear Fos immunoreactivity in guinea pig myenteric neurons following activation of motor activity.

Fos expression can, with some caution, be used to identify classes of enteric neurons activated by different stimuli under various experimental conditions, indicating that expression depended on nerve activity.

Immediate-Early Gene Expression in the Inferior Mesenteric Ganglion and Colonic Myenteric Plexus of the Guinea Pig

It is suggested that colitis enhances reflex activity of the IMG by a mechanism that involves activation of both primary afferent fibers and the myenteric plexus.

Distribution of excitatory vagal fibers in canine gastric wall to control motility.

Identification and stimulation by serotonin of intrinsic sensory neurons of the submucosal plexus of the guinea pig gut: activity- induced expression of Fos immunoreactivity

The data suggest that intrinsic primary afferent neurons are located in the submucosal plexus, project to the myenteric plexi, and are activated by 5-HT acting on the 5- HT1P receptor subtype, which is mediated by the enteric nervous system.

Capsaicin‐sensitive vagal stimulation‐induced gastric acid secretion in the rat: evidence for cholinergic vagal afferents

Results indicate that capsaicin‐sensitive afferent fibres contribute to the acid secretory response induced by electrical vagal stimulation in the rat, which may be cholinergic, since atropine and hexamethonium totally abolishvagal stimulation‐induced acid secretion.

Brainstem pathways responsible for oesophageal control of gastric motility and tone in the rat

The results suggest that the gastric relaxation evoked by oesophageal distension is critically dependent on intact brainstem vago‐vagal circuits.

Topography of efferent vagal innervation of the rat gastrointestinal tract.

The considerably overlapping innervation of the duodenum does not satisfy a viscerotopy criterion and needs further functional analysis, while there is some degree of specific innervation by the abdominal vagal branches of the oral-to-anal gut axis.

Vagal inputs to these neurochemically and topographically distinct enteric neurons provide the basis for the physiological vagal control of gastrin release, gastric acid secretion, and gastric motility.
