Exploration levels in the ORT.

This table shows the number of animals (n) and mean exploration time (± SEM) in seconds on both the objects in T1 (e1) and T2 (e2) in every treatment condition. SOL, SOC, and EE animals were tested repeatedly, so every individual animal performed each experimental condition once. The 1 h retention interval was tested first, followed by the 24 h interval conditions. Finally, the 48 h retention interval conditions were tested. Of note, although a total number of 22 SOL, 18 SOC and 18 EE animals were tested in each condition, animals that explored less than 6 s in T1 and/or less than 9 s in T2 were excluded from the analyses.Exploration levels in the ORT.
