COMPLETE SOLUTION| Graded A+
Draw an action potential in the axon of a neuron and indicate which ions flow into the neuron
and out of the neuron as the action potential passes at the point where the electrodes are in the
cell. Be sure to assign on the Y-axis the mV of each of these areas. This should be as
described in my lectures. -
