Spatial reach is similar across brain regions. A, Across frontocentral cortex, surface coherence reached 2.84 cm, showing significant power law decay for delta (p < 0.001), theta (p < 0.001), alpha (p < 0.001), beta (p < 0.001), and gamma (p < 0.001) signals. Surface-depth coherence reached 3.17 cm across frontocentral cortex and showed decay for only alpha signals (p = 0.027). SFC reached an estimated 2.77 cm across the frontocentral cortex. Power law decay was observed for delta (p = 0.011), theta (p < 0.001), alpha (p < 0.001), beta (p = 0.003), and gamma (p = 0.001) SFC. B, Across middle temporal cortex, surface coherence reached ∼2.44 cm, showing decay for delta (p < 0.001), theta (p < 0.001), alpha (p < 0.001), beta (p < 0.001), and gamma (p < 0.001) signals. Surface-depth coherence reached 2.43 cm across middle temporal cortex, showing decay for delta (p = 0.008), theta (p = 0.022), and alpha (p < 0.001) signals. SFC across the middle temporal cortex reached an estimated 2.27 cm across temporal cortex, showing decay was observed for delta (p = 0.005), theta (p = 0.004), alpha (p = 0.001), beta (p = 0.001), and gamma (p = 0.001) SFC. C, Across posterior temporal cortex, surface coherence reached 2.43 cm and showed decay for delta (p = 0.020), theta (p = 0.043), alpha (p = 0.043), beta (p = 0.031), and gamma (p = 0.025) frequencies. Surface-depth coherence reached 2.56 cm and showed no power law decay across posterior temporal cortex. SFC reached an estimated 2.21 cm. There was no significant decay for SFC in this region, and only delta signals showed a trend (p = 0.087).
