Four peak values for the input EPSP were considered (peak values at right). Inset at top shows two representative EPSPs, both with $2.4\tmspace  +\thinmuskip {.1667em}mV$ peaks and a time-to-peak of $1\tmspace  +\thinmuskip {.1667em}ms$ and $10\tmspace  +\thinmuskip {.1667em}ms$, respectively (scale bar $10\tmspace  +\thinmuskip {.1667em}ms$, $2\tmspace  +\thinmuskip {.1667em}mV$). EPSPs were simulated by an ``alpha-function'' (see {\bf  Methods}). Arrows at bottom mark $SIE$ for these representative EPSPs. ({\bf  b}). As in ({\bf  a}) but the input synapse injects a fixed charge (see Methods). Inset depicts two EPSPs, both with input charge of $0.1\tmspace  +\thinmuskip {.1667em}nC$ and a time-to-peak of $1\tmspace  +\thinmuskip {.1667em}ms$ and $10\tmspace  +\thinmuskip {.1667em}ms$, respectively. ({\bf  c}) and ({\bf  d}). Input EPSP (top frames, same EPSPs as in insets of ({\bf  a}) and ({\bf  b})) and the corresponding raster plot (middle), and cross-correlation (CC, bottom). In the raster plots, for every input spike (aligned at time zero), the output spikes in the following $30\tmspace  +\thinmuskip {.1667em}ms$ time-window are plotted. Plots are sorted such that cases with at least $1$ output spike in the time-window considered appear in the lower part. Spikes preceding the input spikes where omitted for clarity. Horizontal dashed line shows the number of time-windows containing spikes that are expected by chance. (Computed by sampling the $200 s$ long output spike train randomly in $30 \tmspace  +\thinmuskip {.1667em}ms$ bins, and multiplying the proportion of windows containing at least $1$ spike by the total number of input spikes). The CC (lower frames) is computed between the input spike train and the output spike-train (open area), as well as between one ``background'' spike train and the output spike train (filled area). Bin size of $1\tmspace  +\thinmuskip {.1667em}ms$ was used. Same I\&F model as in Fig.\nobreakspace  {}2\hbox {} was used.}}}{97}}
