Prefrontal cortex connectivity during right and left hand dexterity tests in younger and older adults
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.
