Brain on autopilot
Date:1/16/2014

This news release is available in German.

The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain? To answer this question, researchers at the Max Planck Institute for Human Development in Berlin, in cooperation with colleagues at the Free University of Berlin and University Hospital Freiburg, have for the first time analysed 1.6 billion connections within the brain simultaneously. They found the highest agreement between structure and information flow in the "default mode network," which is responsible for inward-focused thinking such as daydreaming.

Everybody's been there: You're sitting at your desk, staring out the window, your thoughts wandering. Instead of getting on with what you're supposed to be doing, you start mentally planning your next holiday or find yourself lost in a thought or a memory. It's only later that you realize what has happened: Your brain has simply "changed channels"and switched to autopilot.

For some time now, experts have been interested in the competition among different networks of the brain, which are able to suppress one another's activity. If one of these approximately 20 networks is active, the others remain more or less silent. So if you're thinking about your next holiday, it is almost impossible to follow the content of a text at the same time.

To find out how the anatomical structure of the brain impacts its functional networks, a team of researchers at the Max Planck Institute for Human Development in Berlin, in cooperation with colleagues at the Free University of Berlin and the University Hospital Freiburg, have analysed the connections between a total of 40,000 tiny areas of the brain.
