create axon axon { nseg = 75 diam = 100 L = 20000 insert hh }
The basic tools you'll need from the
NEURON
Main Menu
:
Tools / Point Processes / Manager / Point Manager to specify
stimulation
Graph / Voltage axis
and
Graph / Shape plot
to create graphs of v vs t and v vs x.
Tools
/ RunControl
to run the simulation
Tools / Movie Run to see a smooth evolution of the space plot in time.
2) Change excitability by adjusting sodium channel density.
Tool needed:
Tools / Distributed Mechanisms / Viewers / Shape Name
3) Use two current electrodes to stimulate both ends at the same time.
4) Up to this point, the model has used a very fine spatial grid (nseg =
75).
Change nseg to 15 and see what happens.
