Table 4.

Exploration times (in s) with administration of ITI-214 2 h before T2 in the NOR: retrieval. Different dosages of ITI-214 were administered 2 h before T2. The delay interval between the first and second trial was 24 h. n = 20 per experimental condition

No differences were found between treatment conditions in exploration times in T1 (e1: F(5,119) = 0.81, n.s.) not in T2 (e2: F(5,119) = 0.99, n.s.)
