  1. The table shows as well the selected upper boundary as result of the parameter space search which resembled best the spike and burst rate of the experimental data (see "Methods" section/ INEX model). The table is visualized in Fig. 3
  2. The spike rate SR is given in spikes per minute, the burst rate BR in bursts per minute, the burst duration BD in seconds and the average number of spikes per burst SB as count.
