Supporting Figure 7

Fig. 7. The rate of plasticity depends on the initial synaptic strength, because of the decay term. Potentiation ratio [W(final)/W(0)] is plotted as a function of the initial synaptic weight W(0). LTP induced using a postsynaptic potential of V = –20 mV and 40 presynaptic pulses (blue) is larger for initially weaker synapses. LTD induced using V = –55 mV and 40 pulses (red) is larger at synapses that were initially stronger.
