Figure 4. Long-term memory: Novel object recognition with the retention period of 24 hours.

Figure 4

A: Time of object exploration during acquisition. There was no difference between the groups, and no effect of JZL184-treatment on the exploration time. B: Testing phase. Left: Time of object exploration during testing was smaller in vehicle-treated Ts65Dn vs. 2N mice. There was no such difference between the JZL184-treated Ts65Dn and 2N groups. Right: Discrimination index was smaller in the vehicle-treated Ts65Dn vs. 2N mice. JZL184-treatment significantly increased the discrimination index in Ts65Dn mice, but had no effect on the performance of their 2N littermates.
