The properties of LTP in neonatal layer IV neurons are a consequence of the change in shape of the underlying EPSC and the membrane properties of the neurons. A, Superimposed voltage responses (EPSP waveforms; top) produced by somatically injected EPSC waveforms (bottom) for an example set of EPSC waveforms. Baseline EPSC (EPSCbaseline; black) and LTP EPSC (EPSCLTP, gray) pairs (left) are shown. Baseline EPSC (EPSCbaseline; black) and baseline EPSC scaled to the peak of the LTP EPSC (EPSCscaled; gray) pairs (right) are shown. B, Resulting EPSP waveforms for the experiment in A, scaled and superimposed, are the EPSCbaseline/EPSCLTP pair (top) and EPSCbaseline/EPSCscaled pair (bottom). C, Pooled data for changes in EPSC amplitude (ampl.) with LTP for the four data sets used and the change in EPSP waveform amplitude and slope for EPSCLTP (left) and EPSCscaled (right). D, Ratio of EPSC slow component: EPSC peak plotted versus mean EPSP peak amplitude change for EPSCLTP. The line is a linear regression (r2 = 0.41; p < 0.001). ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.005.
