What happens when a neuron is sufficiently stimulated by incoming signals from other neurons that ion channels open and positive ions move into a neuron?
A) The cell goes into refraction.
B) An action potential occurs.
C) The polarization of the cell increases.
D) Transmitter substances are synthesized.
