Figure 3. Performance of GluN1.

^hypo(HYPO) and WT mice in discrete trial spontaneous alternation (a) and the spatial novelty Y-maze (b) tasks. In the spontaneous alternation task (a), WT mice show a high level of performance while GluN1^hypo mice were at chance levels. In the spatial novelty Y-maze (b), the GluN1^hypo mice once again showed deficits compared to the WT mice. Spontaneous alternation is expressed as median and IQR, spatial novelty Y-maze as mean ± SEM of the novelty preference ratio, defined as time spent in novel arm/(time spent in novel arm + time spent in other arm). *P < 0.05 WT vs. HYPO.
