Figure 6


Fig. 6. The quantitative parameters are summated from unitary synaptic inputs under control conditions (open symbols) and upon CaM activation (filled symbols). (A,B) Simulated pulse waves in the control [200 synapses vary among facilitation, depression and parallel in the ratio 12:20:7 (see Fig. 1) and 0.6-1.6 msecond presynaptic inter-input intervals] and upon CaM activation (300 synapses in depression pattern with 0.5-1.0 msecond inter-input intervals). As step two of the simulated waves varies under different conditions and mainly controls the spike programs, we quantified its amplitudes and duration vs inter-input intervals and synapse number. (C) The exponentially decayed correlation between the amplitude and inter-input interval. (D) The linear correlation between the duration and inter-input interval. (E) The amplitude vs the number of synapses. (F) The linear correlation between the pulse duration and the number of synapses.
