Hand and Brain

 

1. General questions on brain and prehension

      1) How does CNS perceive the object (perception problem)
      2) How does CNS solve a problem of kinematic/kinetic redundancy during reaching (inter-segmental dynamics, spacial path)
      3) How does CNS use feedback to compensate errors (feedback control, sensorymotor transformation)
      4) How does CNS solve a problem of kinematic redundancy during prehension (joint angle)
      5) How does CNS solve a problem of kinetic redundancy during prehension (stable grasping)
              (1) finger normal/tangential force control
              (2) safety margin, friction coefficient
              (3) moment control (free moment, moment of force)
              (4) force and moment synergies
              (5) muscle synergy
      6) How does CNS adaptations from prehension experiences
      7) How does CNS use two hands (bimanual coordination)
      8) How does CNS respond to different perturbations, fatigue, etc.
