There was no significant difference among the groups on any day. Rows and columns as explained in the legend of Table 1. All groups had eight rats except LTP group (given primed burst stimulations), and LTP control groups had seven rats. No statistical significance was found among groups at any time, as tested by Wilcoxon test.
