Define the axon of a neuron, Biology

Assignment Help:

Consider an axon of a neuron. At time=t1, its voltage is at threshold for an action potential; at time=t2, its voltage is at 0 millivolts prior to the peak of that action potential. In the time period between t1 and t2 of that single action potential,
