NEURON Tutorial #22


Goals: Compare Fourier Transform of Impedance in Models without and with Ih

Contents:

  1. Voltage traces.
  2. Impedance magnitude.
  3. Impedance phase.
  4. Voltage lag.

Conditions:

Without Ih:
e_pas = -65 (mV)
gbar_h = 0 (S/cm2)

With Ih:
e_pas = -70 (mV)
gbar_h = 4e-5 (S/cm2)
Sonia's Ih model

Summary:

1. Voltage traces

Baseline in voltage is removed.

3. Impedance Phase

Impedance Phase


4. Voltage Lag

Notes

The voltage lag (phase) information is not reliable below 1 Hz.
