Values are mean±S.D. with number of neurons in parentheses. Steady-state f–I slope, the slope of the relationship between steady-state spike frequency vs the amplitude of current pulses injected. Frequency (0.2nA) and (0.5nA) are adapted firing frequency for current pulses of 0.2 and 0.5nA. Other abbreviations, see Table 1. Symbols indicate significance vs comparable normal control group. *P<0.05, **P<0.01, two-tailed Student's t-test.
