When I do

Code: Select all

objectvar stim
soma stim = new IClamp(0.5)

stim.del = 100
stim.dur = 100
stim.amp = 0.1
according to the NEURON tutorial, what are the units of the stim.amp? Thanks.

Very important question. The answer is in the FAQ list under
What units does NEURON use for current, concentration, etc.?
You'll find a link to the FAQ list on the Documentation page

If you wonder why some currents are in mA/cm2 (milliamps/square centimeter) while others are in nA (nanoamps), it will be helpful to read about density mechanisms (also called distributed mechanisms) and point processes in chapter 5 of The NEURON Book; if you don't have the book, then read this
Hines, M.L. and Carnevale, N.T.
The NEURON simulation environment.
Neural Computation 9:1179-1209, 1997
which is available from a link at
