Behavioral symptoms following serial or simultaneous septal-forebrain lesions: similar syndromes.

摘要: Abstract Male hooded rats with serial unilateral septal-lesions exhibited a behavioral syndrome similar to that by counterparts simultaneous bilateral septal-lesions. Subjects lesions and subjects differed from control on measures of open-field activity shock-avoidance performance. However, the lesion groups did not differ each other measures. Rats septal-damage also subjects; therefore, damage was sufficient result in hypoactivity enhanced shock-avoidance. Serial recovery/sparing, regardless whether were 60 or 120 days old at time surgery, housed complex impoverished environment during 30-day interoperative interval. The present findings do confirm previous ones, but they indicate conditions under which exposure environmental complexity facilitate recovery/sparing remain be defined more precisely.
