The higher the frequency of action potentials in the presynaptic cell of an excitatory synapse: The larger the action potential in the postsynaptic cell. The greater the depolarizing stimulus in the postsynaptic cell. The weaker the depolarizing stimulus in the postsynaptic cell. The smaller the action potential in the postsynaptic cell

Summation of excitatory postsynaptic potentials increases the probability that the potential will reach the threshold potential and generate an action potential, whereas the summation of inhibitory postsynaptic potentials can prevent the cell from achieving an action potential.
Increasing the amount of action potentials that arrive at the presynaptic terminal will: (Can pick more than one) Increase the number of vesicles that fuse with the presynaptic membrane Increase the amount of depolarization in the terminal Increase the amount of neurotransmitter released. Increase the amount of Ca2+ that enters the presynaptic terminal.
