Averaged data are given as mean± SD. The plateau potential was induced by depolarizing current steps (5–10 pA, 0.2–1 s). Recordings were made in ACSF containing 1 mm Ca2+. iGluRs and GABAARs were blocked as detailed in Materials and Methods. Unpaired two-tailed t test or Mann-Whitney rank sum test (versus, i.e., left versus right) values are indicated as follows:
-
↵*p < 0.05,
-
↵**p < 0.01. ns, Not significant.
