Network Events on Multiple Space and Time Scales in Cultured Neural Networks and in a Stochastic Rate Model

Fig 4

Algorithms for network events detection.

Panel A: total network activity from simulation (blue line) with detected NS/quasi-orbits (green line) and avalanches (red line). Four large events (green line) are visible; the first and third are statistically classified as network spikes; the other smaller two as quasi-orbits. Note how network spikes and quasi-orbits are typically included inside a single avalanche. Panel B: a zoom over 0.5 seconds of activity, with discretization time-step 0.25 ms, illustrates avalanches structure (red line).
