Enhanced NMDA receptor NR2B/NR2A ratio in the ACC of wild mice. a: Representative traces showing NMDA receptor NR2A and NR2B subunit-mediated EPSCs from wild and control mice; b: Summary of the NR2B/NR2A ratio in slices of control and wild mice. The NR2B/NR2A current ratio is enhanced in wild mice as compared with that in control mice; **P < 0.01, compared with laboratory mice.
