Chronic nonapeptide administration. (a) Mean (±SE) latency (in seconds, s) to reach the platform across nine learning trials for animals receiving saline (diamonds), OT (squares), or AVP (triangles). (b) Mean (±SE) duration of time (in seconds) spent during the memory trial in the quadrant where a platform was previously located for animals chronically administered saline, OT, or AVP during adolescence. Bars show significant post hoc differences; * = p ≤ 0.05.
