<prompt> Which of the following statements is true for excitatory postsynaptic potentials EPSPAre self propagatingShow all or none responseAre proportional to the amount of transmitter released by the presynaptic neuronAre inhibitory at presynaptic terminal  <response>: EPSP is proportional to the amount of neurotransmitter released, so not an all or none activity. It is not self-propagating, nor does it have any action on presynaptic terminal.
