Table 1. Membrane properties of bursting and regular-spiking subicular neurons at 23°C and 33°C
Sag ratio | R-input (MΩ) | Capacitance (pF) | RMP (mV) | |
---|---|---|---|---|
Sag ratio was calculated by dividing the steady-state voltage by the peak voltage response to a hyperpolarizing current injection of 200 pA. R-input, input resistance; RMP, resting membrane potential. *Significant difference between bursting and regular-spiking neurons (P < 0.05). | ||||
