ABSTRACT

This chapter describes the component processes that must be in place to successfully reach for and grasp objects. It discusses the concepts through a concrete neural dynamic model that provides a process account from sensory inputs to generating movement of a simulated biomechanical plant. In a neural process account of reaching, the neural networks of the brain are linked to sensory and motor systems to bring about the motor behaviors that achieve the reaching act. A neural process account is always based on the choice of a particular level of description that entails a particular level of neurally mechanistic detail. The Scene perception is tightly linked to looking and attention. It has been trivialized in the model by assuming that a distribution of activation defined in body-centered coordinates is available to the processes of movement preparation. It is the movement parameters that characterize movements as a whole, that have specific values from the very start of the motor act.
