The coordination of bimanual prehension movements in a centrally deafferented patient.
Many everyday tasks require that we use our hands co-operatively, for example, when unscrewing a jar. For tasks where both hands are required to perform the same action, a common motor programme can be used. However, where each hand needs to perform a different action, some degree of independent control of each hand is required. We examined the coordination of bimanual movement kinematics in a ...
متن کاملCo-ordination of bimanual movements in a centrally deafferented patient executing open loop reach-to-grasp movements.
Many everyday tasks require that we use our hands co-operatively. For tasks where both hands are required to perform the same action, a common motor program can be used. But, where each hand must perform a different action, some degree of independent control of each hand is required. In this paper we examine the co-ordination of bimanual movement kinematics in a female patient recovering from b...
متن کاملIntersegmental Coordination in the Kinematics of Prehension Movements of Macaques
The most popular model to explain how prehensile movements are organized assumes that they comprise two "components", the reaching component encoding information regarding the object's spatial location and the grasping component encoding information on the object's intrinsic properties such as size and shape. Comparative kinematic studies on grasping behavior in the humans and in macaques have ...
متن کاملMovements of Individual Digits in Bimanual Prehension Are Coupled into a Grasping Component
The classic understanding of prehension is that of coordinated reaching and grasping. An alternative view is that the grasping in prehension emerges from independently controlled individual digit movements (the double-pointing model). The current study tested this latter model in bimanual prehension: participants had to grasp an object between their two index fingers. Right after the start of t...
متن کاملMonitoring Coordination during Bimanual Movements: Where Is the Mastermind?
One remarkable aspect of the human motor repertoire is the multitude of bimanual actions it contains. Still, the neural correlates of coordinated movements, in which the two hands share a common goal, remain debated. To address this issue, we designed two bimanual circling tasks that differed only in terms of goal conceptualization: a "coordination" task that required movements of both hands to...
