Algorithm 2. Defining the order of the time interval when spike actions A are detected.

Inputs: Cluster $c$, Number of clusters $l$, $PSP$ timeseries, $PSP$ temporal length $T$, Spike-events in clusters $c_i\left(t\right)$ and spike time-interval $ℒ$ Outputs: Rules $R=\left(A, ord\right)$ as set of Action A and time orders Procedure: For $c=1 to l$//for all the clusters $Baseline \leftarrow 1$ While $(Baseline<T-ℒ)$ If ($\mathrm{Length} \mathrm{of} \{c_i\left(\mathrm{Baseline}: Baseline+ℒ\right)>0\} \mathrm{equal} \mathrm{to} ℒ)$ //sequential $ℒ$ number of spikes $Action \left(c, Baseline\right) \leftarrow A$ End If $\mathrm{Baseline}\leftarrow \mathrm{Baseline}+1$ End while End For Print sets of Actions as Rules For c = 1 to $l$ Ord$\leftarrow 1$ For t = 1 to T If $Actions\left(c,t\right)=A$ $R\left(ord\right)$ $\leftarrow Actions\left(c,t\right)$ Ord$\leftarrow ord+1$ End For End For End of Procedure
