The flowchart of our cell sorting algorithm. Intra-cellular calcium signals, Ca(t) are passed to a program which calculates the periodogram PSD and the probability of the peak PSD values. If p < 0.005, cell is sorted as a burster cell. Among non-bursters, cells which satisfy the condition ΔV = |Vmax - Vmin| < 30 mV are considered silent cells, and the rest as spiker cells.
