Coupling indices extracted from high-resolution joint symbolic dynamics, segmented Poincaré plot analysis, and normalized short-time partial directed coherence.

Index	Description
HRJSDxy_Fx-Fy	Probability of occurrence of the Fx and Fy word families from the x–y coupling
HRJSDShxy	Shannon entropy of all the word families from the x-y coupling
HRJSDxy-Fx	Summation of the occurrences of Fx on all the families from the x-y coupling
SPPAxy_Row_n-m	Probability of occurrence of the Row n-m from the x-y coupling
SPPAxy_Column_n-m	Probability of occurrence of the Column n-m from the x-y coupling
JSDxy-n	Probability of occurrence of the word n from the x-y coupling
PPAxy_SD1	Short-time standard deviation from the x-y coupling
PPAxy_SD2	Long-time standard deviation from the x-y coupling
PPAxy_SD1/SD2	Short and long deviations ratio from the x-y coupling
NSTPDCxy_NF	Normalized coupling factor from the x-y coupling
NSTPDCxy_ Ax → y	Coupling strength of x-y from x to y
