d-serine enabled the induction of LTP in GCM cultures. (A) No LTP induction was induced in GCM cultures under control conditions. (B) Supplement of d-serine (10μM) enabled the induction of LTP in GCM cultures. (C) The enabling effect of d-serine was abolished by NMDAR antagonist APV. (D) Summary of results from all experiments, including data shown in A–C and experiments in which l-serine (10 μM) was used instead of d-serine. Asterisks indicate significant difference from the control group (P < 0.001, t test).
