Minimum Muscle-Tension Change Trajectories Predicted by Using a 17-Muscle Model of the Monkey's Arm.

摘要: Abstract Four computational problems to be solved for visually guided reaching movements, hand path, and trajectory formations, coordinate transformation, calculations of muscle tensions are ill-posed in redundant biological control systems. These the sense that there exist an infinite number possible solutions. In this article, it is shown nervous system can solve those simultaneously by imposing a single global constraint: finding smoothest muscle- tension satisfies desired final position, velocity, acceleration. Horizontal trajectories were simulated using 17-muscle model monkey's arm as controlled object. The simulations predicted gently curved paths lateral movements from side body front, roughly straight path anterioposterior movements. tangential velocities bell shaped. results agreement with ...
