They say that practice makes perfect.

But sometimes, the best practice is not on a keyboard.

It's all in your head because a new study shows that the brain takes advantage of the rest

periods during practice to review new skills, a mechanism that facilitates learning.

The work appears in the journal Cell Reports.

A lot of the skills we learn in life are sequences of individual actions.

Leonardo Cohen of the National Institute of Neurological Disorders and Stroke, or N-I-N-D-S.

For example, playing a piece of piano music requires pressing individual keys in the correct sequence with very precise timing.

That level of virtuosity requires a ton of practice and a lot of repetition, but Cohen says it also

requires a certain amount of rest.

We know from previous research that interspersing rest with practice during training is

advantageous for learning a new skill. In fact, we recently show that virtually all early skill

learning is evidence during rest rather than during the actual

practice.

It's during those intermittent breaks that the brain starts to sew together the individual
