A new study suggests activities combining movement and force tax our brains to capacity, countering a long-held belief that difficulty with dexterous tasks results from the limits of the muscles themselves. The findings may help explain why minor damage to the neuromuscular system can at times profoundly affect one's ability to complete everyday tasks. "Our results show how much the mechanics of the body, and a given task, affect what the brain can or can't do," said Francisco Valero-Cuevas. (source: nsf.gov)
