If we understand a liver cell, we understand a lot about the liver. If we understand a brain cell, we still miss much about how the brain works. The billions of brain cells influence each other. These mutual influences bring about dynamics that is only defined at the level of the whole system entailing multiple components. These system level dynamics effect neuronal communication in turn. We look at multiple brain areas, circuits or cells simultaneously to understand the principles behind their interactions, and how those ultimately shape our behaviour.
