Axon of Hillock

This program is a demonstration of how changing the excitatory to inhibitory input to a soma changes the membrane potential of the soma at the Axon of Hillock (vertical bar column).  Once the threshold potential is reached, an action potential is generated.  Continued excitatory stimulation increases the rate of firing of action potentials from the Axon of Hillock.  Decreasing excitatory stimulation by converting excitatory nerve input to inhibitory lowers the membrane potential, slows the rate of action potential generation, and eventually prevents action potential firing when below the threshold potential.
