Age-related changes in the neural correlates of motor performance

N. S. Ward
2003 Brain  
Hand grip with visual feedback activated a network of cortical and subcortical regions known to be involved in the generation of simple motor acts.  ...  These results support the notion that an adaptable and plastic motor network is able to respond to age-related degenerative changes in order to maintain performance levels.  ...  We chose to use hand grip, a ubiquitous motor task, and to modulate one aspect of the performance level of this task (i.e. peak force exerted during hand grip) by visual feedback.  ...

Planning of visually guided reach-to-grasp movements: Inference from reaction time and contingent negative variation (CNV)

Manuel Zaepffel, Thomas Brochier
2011 Psychophysiology  
Along with RT data, it confirms that two distinct functional networks are involved with different time courses in the planning of grip and force.  ...  We manipulated two parameters: the hand shape for grasping (precision grip or side grip) and the force required to pull the object (high or low).  ...  The map for the noninformative condition (NO) was subtracted from the maps for each informative condition (ALL, GRIP, FORCE). Color transitions in the color scales represent 1 mV steps.  ...
