So I was playing around with neuron last night. I had a 3x500um long cable, with passive properties vaguely like a layer V dendrite. I applied alphaSynapses over the length of the cable, and had a voltage clamp or current clamp electrode at one end. I saw your typical exponential attenuation of the EPSP/C. However, against my assumption, the EPSP/C attenuated to a greater extent when the recorded was done in voltage clamp (i.e. soma.v(0)) vs voltage clamp (i.e. SEClamp[0].i)
Why is this?
I would have thought the (albiet partial) voltage control along the cable would mean that voltage clamp would reduce capacitive currents (i.e. less C*dv/dt), and therefore would retain more longitudial current and you would get less attenuation.
P.S. I measuring EPSP/C amplitude, as peak amplitude.
