WebA stimulus from a sensory cell or another neuron depolarizes the target neuron to its threshold potential (-55 mV). Na + channels in the axon hillock open, allowing positive ions to enter the cell (Figure 16.10 and Figure 16.11). Once the sodium channels open, the neuron completely depolarizes to a membrane potential of about +40 mV.
