Table 1Comparison of the intrinsic properties of layer V pyramidal neurons from wild-type (+/+) and Kcna1-null (−/−) mice*
AP Amplitude, mV
AP Threshold, mV
AP Width at base, ms
AP Half-width, ms
*Values are reported as mean±S.E.M. Number of neurons is indicated in parentheses; RN, input resistance calculated from peak voltage responses to small (5–10mV) hyperpolarizing current pulses; RMP, resting membrane potential; AP, action potential; AP Amplitude, peak AP amplitude measured from RMP; AP Threshold, AP threshold relative to RMP measured from the inflection point just prior to the AP upstroke; AP Width at base, width of the AP measured at threshold; AP Half-width, width of the AP measured at a point halfway between threshold and peak.
