TABLE 1.

Electrode grid information for all participants (both HD and clinical low‐density)

Patient	No of electrodes	Grid hemisphere	Cortices covered	Handedness	Language dominance	Grid
S1	128	L	F, M, T	R	L (fMRI)	HD
S2	128	R	T, P, O	R	L (Wada)	HD, LD
S3	64	R	F, M, T, P	R	L (fMRI)	LD
S4	64	L	F, M, T, P	R	L (fMRI)	LD

Note: The table shows information about the number of electrodes, grid hemisphere, covered cortices, handedness, and language‐dominant hemisphere per patient.

Abbreviations: F, frontal cortex; fMRI, functional magnetic resonance imaging; L, Left; M, motor cortex; O, occipital cortex; P, parietal cortex; R, right; T, temporal cortex.
