Understanding neural engagement of Motor imagery facilitates development of various Brain-Computer Interface systems for rehabilitation purposes effectively. This study brings more insights on the neural underpinnings and associated functional connectivity of basal-ganglia, temporal and frontal-parietal regions during both Motor Imagery (MI) and Motor Action (MA) gripping tasks of randomised left, right and both hands movement with fifteen right-handed volunteers, using EEG-engagement index informed fMRI and functional connectivity approach. Functional connectivity analysis of the neural correlates reveal statistically elevated engagement of basal-ganglia, superior temporal gyrus and frontal-parietal regions in imagery, left handed imagery/action and both hand gripping tasks respectively.
