![]() ![]() ![]() "The integrated patterns were those that were unique for a particular combination of key-press order and timing, not something that transferred across these combinations," Kornysheva said. Then, when it comes time to actually play the notes, these separate patterns representing note order and timing become integrated, or "zipped," resulting in a new, unique pattern of brain activity. "This happens very rapidly and automatically each time in the hundreds of milliseconds before the action starts," Katja Kornysheva (opens in new tab), the study's senior author and co-director of the Centre for Human Brain Health at the University of Birmingham in the U.K., told Live Science in an email. In other words, specific patterns of brain activity reliably translated to particular sequences of notes, and separately, other activity patterns reflected the durations of those notes. These scans revealed that movement-related regions of the brain's wrinkled outer surface, the cerebral cortex, lit up during the planning stage, and this activity reflected the order and timing of the notes to come.
