While before, we used to think of the brain as a modular, centralized organ, where a given area was responsible for a set of actions and behaviors, the more we know about the brain, the more we think of it as a large music symphony, played by hundreds and thousands of instruments.
Aiemmin ajattelimme aivojen olevan modulaarinen elin, jossa tietty alue vastasi tietyistä toiminnoista. Mitä enemmän tiedämme aivoista, sitä enemmän koemme  ne sinfoniana, jossa on tuhansia soittimia.
