Outgoing supernode number averaged across different cultures harvested from the same tissue batch when using a 150 ms time window. A) shows results for 6 dense culture batches. B) shows results for 2 sparse density culture batches and C) for 2 small density cultures. Black solid lines represent the average supernode number within batches, blue dotted lines represent missing experimental data points and red vertical lines are the corresponding standard errors. n represents the population size for each batch.
