Practice makes the brain's motor cortex more efficient, Pitt researchers say

Not only does practice make perfect, it also makes for more efficient generation of neuronal activity in the brain's primary motor cortex, say researchers from the University of Pittsburgh School of Medicine. Their findings, published online today in Nature Neuroscience, showed practice leads to decreased metabolic activity for internally generated movements, but not for visually guided motor tasks, and suggest the motor cortex is "plastic" and a potential site for the storage of motor skills.
