Synaptic Variability Introduces State-Dependent Modulation of Excitatory Spinal Cord Synapses

Figure 3

(a) Graph showing the relationship between the change in the EPSP amplitude (/) and the EPSP half-width at connections that were reduced or potentiated by substance P. (b) Bar graph showing the effects of blocking the NMDA component of the EPSP with AP5 (100 μM) on the EPSP modulation by substance P. Effects are shown in comparison to the normalized control EPSP amplitude and half-width.
