Effects of test experience on behaviors and plasma corticosterone levels in the elevated plus maze in male C57BL/6J mice. Mice that were subjected to behavioral tests other than the elevated plus maze test (n = 16) and mice with no test experience (n = 16) were tested in an elevated plus maze. a Distance traveled (cm), b number of total arm entries, c time spent in closed arms (s), d time spent in center area (s), e percentage of open arm entries (%), and f percentage of time spent in open arms (%) were measured. g Plasma corticosterone levels (ng/mL) of the mice exposed to the elevated plus maze were determined. Values are the means ± SEM
