The effect of a mental stress model corresponding to conditioned fear on cecocolonic motility was evaluated electromyographically in intact and hypophysectomized rats equipped with electrodes implanted in the cecum and proximal colon over a long period and a small polyethylene catheter inserted into the right lateral ventricle of the brain. Intact fasted and fed rats showed an increase of 82.3% and 67.2%, respectively, in colonic spike-burst frequency when placed for 30 minutes in a box in… CONTINUE READING
