*Basal plasma corticosterone correlated positively with time spent in the open arms in the 5^th minute of the EPM, distance travelled in the EPM, time spent climbing in the 1st minute of the FST, and time spent swimming in the FST, while it correlated negatively with time spent immobile in the FST (p < 0.05).
