All data are given as mean ± SEM. Two-way ANOVA showed no difference in resting membrane potential (n = 42; deprivation status, F_1,39 = 0.01, P = 0.91; trim duration, F_1,36 = 0.84, P = 0.37), input resistance (n = 42; deprivation status, F_1,39 = 0.23, P = 0.64; trim duration; F_1,39 = 0.38, P = 0.54) or membrane time constant (n = 39; deprivation status, F_1,36 = 0.59, P = 0.45; trim duration, F_1,36 = 1.83, P = 0.19) when deprived and spared cortex following 5-day deprivation or 10–14 day deprivation were compared. One-way ANOVA showed no difference in resting membrane potential (5-day trim, F_2,34 = 0.23, P = 0.80; 10-day trim, F_2,25 = 0.02, P = 0.98), input resistance (5-day trim, H = 0.66, P = 0.72; 10-day trim, F_2,25 = 0.20, P = 0.83) or membrane time constant (5-day trim, F_2,31 = 0.67, P = 0.52; 10-day trim, F_2,25 = 0.53, P = 0.59) when deprived and spared cortex were compared with pooled controls.
