Acute partial restraint stress activates distal colonic myenteric neurons. Distal colon longitudinal muscle myenteric plexus (LMMP) whole mount tissue from control and mice submitted to 60 min of acute partial restraint stress were processed for Fos immunohistochemistry. A: photomicrographs of distal colon LMMP from control (no stress) and acute stress mice. B: number of Fos immunoreactive LMMP neurons (nb/ganglia) in control and stressed mice (n = 6/group). *P < 0.05 vs. no-stress (control). Scale bar = 100 μm.
