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

Figure 6

(a) Graph showing the lack of a significant difference in the EPSP amplitude at connections where metaplasticity or release probability-dependent plasticity occurred. (b) Graph showing the PP ratio at connections where different forms of activity-dependent plasticity occurred. (ci) Graph showing the relationship between the initial EPSP amplitude and the plasticity in control and in substance P (cii). (di) Graph showing changes in the PP ratio for the different forms of plasticity. (dii) Traces showing the changes in EPSP amplitude over spike trains.
