Grandmasters call on regions of the brain not used so much by less skilled amateurs.

The brain's medial temporal lobe structures are thought to be important for the initial formation of long-term memory1, 2, and active memory is indicated by bursts of gamma-band activity in these and other areas of the association cortex3, 4. Here we use a new technique of magnetic imaging to compare focal bursts of gamma-band activity in amateur and professional chess players during matches.
