Fig. 1. Clustering of spontaneous burst activity of two neuronal cultures in vitro with the following IDs: 3035 (A) and 3040 (C); percentage of bursts in clusters with the following IDs: 3035 (B) and 3040 (D). Bursts are presented as they appeared. Red dotted lines represent days of culture development
Fig. 2. Switching of activity patterns after stimulation without feedback and with feedback. (A) Before stimulation. (B) After stimulation without feedback. (C) After stimulation with feedback
Fig. 3. Averaged burst feature vectors for clusters containing at least 5 % of all events shown in fig. 2. Green line (1) represents electrode 12, on which the culture was trained. Red line represents electrode 22, on which stimulation was performed
