Integration of Visual and Somatosensory Information for Preshaping Hand in Grasping Movements

The primate brain must solve two important problems in grasping movements. Thefirst problem concerns the recognition of grasped objects: specifically, how does the brain integrate visual and motor information on a grasped object? The second problem concerns hand shape planning: specifically, how does the brain design the hand configuration suited to the shape of the object and the manipulation task? A neural network model that solves these problems has been developed.
