(A) Interictal spike propagation patterns were analyzed across different frequency bands (delta, theta, alpha, beta, gamma and high frequency oscillations). Highly consistent propagation patterns were observed within each frequency band. As an example, spike propagation patterns across different frequency bands for EP187 shows high levels of consistency. (B) This is a box plot superimposed on scatter plot showing multiple correlation coefficients among frequency bands revealing high significance for all 10 patients. Data presented within each box shows the multiple correlation coefficient value for each frequency band with all other frequency bands. Each column in a box represents a single patient and each marking within the column represents the multiple correlation coefficient for 10 minute ECoG. The mean ± SD for each frequency are (Delta: 0.9±0.05, Theta: 0.94±0.04, Alpha: 0.96±0.03, Beta: 0.96±0.04, Gamma: 0.92±0.13, HFO: 0.94±0.05)
