Simulation Experiments for Neural Pulses - Brain Theory from a Circuits and Systems Perspective - page 190

• Show in a plot how sodium current can be made to double (slow) the rise time of
the pulse ( 55 to +40 mV).

• Show in a plot how potassium current can be made to double (slow) the fall time
of the pulse.
• What is the minimum current amplitude of a trigger pulse?
Note triggering is accomplished at a nominal 5 nA with:
itrig 0 1 dc 0 pwl ( 0 , 0 , 10us , 5n , 0 . 2ms , 5n , 0 . 21 ms , 0 )

• Restore parameters that were changed.
