A, The simulated AMPAR- and KAR-mediated EPSPs were used in simulations in which a single afferent fiber is stimulated at a single constant frequency. The AMPAR-mediated response (left) caused little summation at firing frequencies, whereas the KAR-mediated response (right) caused substantial summation. B, The tonic depolarization, defined as the minimum depolarization once steady state is reached, is shown for AMPARs (filled circles) and KARs (open circles). C, The peak depolarization, defined as the maximum depolarization once steady state is reached, is shown for AMPARs (filled circles) and KARs (open circles).
