Each table cell shows the number of relationships that were found to be significant at the level, out of the total number of relationships tested. Note that relationships were only tested in cases where both recordings in the pair had at least 10 significant transfer entropy (TE) values. A hypothesis test is conducted against the null hypothesis that the original p-values that produced these results were uniformly distributed between 0 and 1 (giving a 0.05 chance of a significant result). * indicates that this probability is less than 0.05. ** indicates that the probability of the observed number of significant results has probability less than 0.001 under this null hypothesis, with a Bonferroni correction for multiple comparisons. The first row summarises the significance values for the value of the TE on the edges, shown in Figure 3 and Appendix 3—figure 4. The second and third rows summarise the significance values for the mean outward and inward TE on each node, shown in Figure 4 and Appendix 3—figure 5 as well as Appendix 2—figure 1 and Appendix 3—figure 6, respectively. The final row summarises the significance values for the ratio of inward to outward burst-local TE, shown in Figure 6 and Appendix 3—figure 9. The columns which restrict the analysis to bursting recordings exclude the final recording of culture 1-5, as this culture ceased bursting, after having previously been bursty (Wagenaar et al., 2006b).
