Dynamic formation of functional networks by synchronization.
The cerebral cortex consists of numerous, densely interconnected, functionally specialized areas that need to cooperate in ever-changing constellations depending on the actual cognitive or executive task. One way to achieve this dynamic coordination could be phase-locking of synchronized oscillatory activity. In this issue of Neuron, Hipp et al. provide supportive evidence by analyzing EEG signals associated with an ambiguous audiovisual discrimination task.
