Comparison of temporal and spatial specifications on electrical and neuroimaging monitoring methods [3].

Category	Electrical Response	Hemodynamic Response
Temporal resolution	High (limited by sampling frequency) [42,43]	Limited (limited by sampling frequency) [44,45]
Temporal sensitivity	High (limited by sampling frequency) [42,43]	Limited (limited by the hemodynamic response of the brain) [46,47]
Spatial sensitivity	Limited (depends on no. of electrodes) [42,48]	High (fNIRS) [45]
Sensitive to movement	Sensitive to eye, head, body and etc. movement. Noise filtering algorithms are required.	Might need to filter out heart activity from the raw measurements.
Intrusiveness	More intrusive [42]	Low
