In the context of the neural impulse, which of the following is true about the depolarization of neuron membranes?
A)It is characterized by more negatively charged ions on the inside of the cell and more positively charged ions on the outside.
B)It occurs when there is a decrease in the charge difference between the fluids inside and outside of the neuron.
C)It is the brief wave of positive electrical charge that sweeps down the axon.
D)It is the phase that allows sodium ions to move out of the neuron.

Depolarization occurs when there is a decrease in the charge difference between the fluids inside and outside of the neuron. This is because depolarization involves a temporary influx of positively charged ions into the neuron, which brings the charge inside the cell closer to the charge outside the cell. This reduction in charge difference is what triggers the neural impulse.
