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.

2. Impedance Magnitude

3. Impedance Phase

4. Voltage Lag

Notes

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