Fig. 3: Within- vs across-module communication.

a Average raw Granger spectra for an individual MEA. b Normalizing the Granger causality spectra to have area 1 allows for the comparison of within- vs across-module connectivity as a function of frequency. c Difference in GC as a function of frequency band across all MEAs. Across all MEAs, within-module communication contains significantly larger broadband gamma and significantly smaller delta, theta, and alpha contributions when compared to across-module communication. There is no significant difference for the beta band.
