Passive and active membrane properties in control versus epileptic CA1 pyramidal cells

Naive-control Sham-control Epileptic
Vm (mV) −64.3 ± 3.1 (36) −64.0 ± 3.9 (38) −63.8 ± 3.8 (139)
Rm (MΩ)  45.7 ± 18.3 (32)  45.4 ± 14.3 (32)  43.3 ± 17.1 (125)
AP threshold (mV) −53.9 ± 3.8 (36) −53.0 ± 4.2 (38) −53.2 ± 4.5 (139)
AP amplitude (mV)  90.2 ± 8.3 (36)  89.6 ± 6.0 (38)  89.5 ± 8.9 (139)
AP width (ms)   2.0 ± 0.2 (35)   2.1 ± 0.4 (33)   2.0 ± 0.3 (104)
  • For each of the three groups of animals examined (naive-control, sham-control and epileptic), the resting membrane potential (Vm) and input resistance (Rm), and the action potential (AP) threshold, amplitude and width are provided as means ± S.D. (n), where S.D. is the standard deviation and n is the number of observations. No significant differences in these parameters between the control groups and the epileptic group were found (Student's unpaired t test).
