Manual dexterity, strength, fatigue, and perseveration: an initial test of asymmetry in cerebral activation.
50 right-handed men were evaluated on right and left hand-grip strength, fatigue, and perseveration tasks and on a finger-tapping task. Subjects were tested in combined ambient sensory conditions of bright light and noise, bright light and quiet, dim light and noise, and dim light and quiet to provide an initial test of asymmetrical activation of the hemispheres. Analysis did not support the hypothesized asymmetry in activation. However, increased fatigue and perseveration were found using the left hand.
