When neurotransmitters bind with receptor sites, what is the essential event that eventually causes the postsynaptic neuron to generate an action potential?
A) the creation of myelin sheathing
B) the flooding of sodium (Na+) into the cell
C) the removal of anions from the cell
D) the generation of electrical current in the dendrites
