 RMP (mV)IR (mΩ)AP threshold (mV)AP width (ms)AP height (mV)
  1. Deletion of CaV1.3 did not significantly alter any of the properties that were measured. RMP and AP threshold values were not corrected for liquid junction potential. All data are presented as mean ± S.E.M.

  2. RMP, resting membrane potential; IR, input resistance; AP, action potential.

CaV1.3+/+60.3 ± 0.7150.3 ± 8.654.3 ± 0.41.4 ± 0.0487.8 ± 2.1
CaV1.3−/−59.3 ± 0.7155.6 ± 15.554.8 ± 0.51.4 ± 0.0386.7 ± 2.6
