Dynamic Brain Network

A German-led study measuring the human brain's electrical currents has confirmed the theory the mind requires the cooperation of several brain areas.

Human knowledge is definitely not stored in one single brain area, said study leader Thomas Gruber of the University of Leipzig. Access to knowledge results from the cooperation of several brain areas that jointly build a dynamic brain network.

He said the study confirmed recognition of familiar and unfamiliar objects activates a set of distributed brain areas, and -- for the first time -- it measured how brain areas communicate with each other by directed information transfer.

The study showed cooperating brain areas are not just connected, but each area can be engaged either in receiving or sending signals or both.

Until now this has been difficult to investigate, but our analysis suggests that most areas are involved in both during access to object-related knowledge, said first author Gernot Supp of the Max-Planck Institute of Human Cognitive and Brain Science.
