Abstract

Functional connectivity of the PFC evaluated by fNIRS not only differed in Older versus Younger adults but the ∆O2Hb, a surrogate of neural activity, showed more pairing between regions during hand dexterity by the non-dominant hand. Age and non-dominant hand required more connectivity but did not lead to improved task efficiency.
