Figure 3From: Cingulate NMDA NR2B receptors contribute to morphine-induced analgesic toleranceNo change in mEPSCs in morphine treated mice. (A) Representative traces showing mEPSCs in saline (upper) or morphine treated mice (lower). (B) Pooled data showed that there is no difference in mEPSC frequency in saline (n = 16) and morphine treated groups (n = 16). (C) No difference in amplitude of mEPSCs in the ACC of saline (n = 16) and morphine treated groups (n = 16).Back to article page
