The table summarizes average ± SEM values (cells analyzed are in brackets) for membrane approximate ‘resting’ potential (RP), time constant (τmemb), input resistance (Rin), capacitance (Cm), spontaneous action potential firing (SponAP, in whole-cell), rheobase (Rheo) and AP threshold (Vthre). Bottom, relevant p values.
