aAmplitude, 10–90% rise time and half-width are presented as median values calculated from grouped results in each type of mice. Values in parentheses represent 25th and 75th percentiles. Non-overlapping, spontaneous events were obtained in perfusate containing CNQX, AP5 and TTX (mIPSCs) or AP5, BMI and TTX (mEPSCs). Comparisons were made for n=1787 mEPSCs collected in five cells (wild-type, +/+), 1351 mEPSCs from seven cells (kcna1-null, −/−), 3435 mIPSCs from 11 cells (+/+) and 4214 mIPSCs from 14 cells (+/+). Each individual cell contributed 100 or more events to the grouped results.
