Abstract
Visual perception requires parallel processing of distributed information. To achieve true parallelism, in which multiple patterns can be processed simultaneously, dynamic synchronization in ongoing, oscillatory brain activity plays a crucial role. On a large time scale, it can help create and maintain an optimal brain connectivity structure that is clustered, modular, and connected. Over a range of shorter time scales, dynamic synchrony is instrumental in coordinating and controlling the flow of information in the brain. Dynamic synchronization modulates in a pulsed manner the receptivity of sensory systems, the effectivity of neural communication and the binding of visual stimulus information. Collectively, these processes control communication in the brain and determine what we experience.
