The present study examined if olfactory bulbectomy (OBX) altered defensive
behaviors on the elevated plus-maze and the open-field differently in male
and female rats. Similar increases in defensive behaviors in male and femal
e rats were observed in both tests following OBX. No significant correlatio
ns were detected between defensive behaviors and activity. supporting the h
ypothesis that some behavioral changes following OBX may be due to decrease
d defensive behaviors and not increased activity. (C) 2001 Elsevier Science
