Before revision:  These results show that the appropriate diversity in the properties of neurons and muscles across layers and within levels help create systems that are both fast and accurate despite being built from components that are individually slow or inaccurate. This novel concept, which we call "diversity-enabled sweet spots" (DESSs) , explains the ubiquity of heterogeneity in the sizes of axons within a nerve as well the resulting superior performance of sensorimotor control .
