resistance of electrode in IClamp

[xyang]

When we using IClamp in point process manager in NEURON, is there a real electrode, and does that electrode has a resistance or capacitance?

Thanks!

I hope not. I don't want broken glass and salt water inside my computer.

Clowning aside, an IClamp object is a perfect current source. Its "source resistance" is
infinite, but there is no resistor between it and the point on the model cell to which it is
attached.

If you want to simulate the effects of electrode resistance and capacitance on the
experimentally observed voltage, you can use the Linear Circuit Builder to create a model
that combines a model cell, an equivalent circuit of an electrode, and a current source.

Thanks for the reply! That helps!
