Mean total ulcer length (± SEM) in mPFC-lesioned rats induced by a single 2.5 hr cold restraint session. A significant effect of mPFC lesion was observed (F(3,58)= 8.98; p < 0.0005), with no significant effect of treatment and no lesion × treatment interaction. Regardless of previous experience with acute (A) or repeated (R) 20 min restraint stress, bilateral and right lesion groups each differed significantly from both the shams and left-lesioned animals (Tukey’s post hoc analysis; *p < 0.05 in each case). Left-lesioned rats did not differ from shams, nor did right-lesioned rats differ from the bilateral lesion group. The inset reveals these pronounced lesion effect with treatments collapsed. S,L, R, and B refer to sham, left, right, and bilateral mPFC lesion groups, respectively.
