The brain has been seen through two conflicting views: one speaking of its regional specialization, with the idea that information travels to specialized centers; and the other emphasizing its globally integrated activity, of which consciousness is the ultimate example. Specialized brain regions may exhibit enhanced and more coherent activity, leading to the genesis of local oscillations. In turn, global integration may coordinate these oscillations via transient phase locking or metastability [learn more]. These coordinated oscillations may be discovered through the analysis of their relative phase dynamics.

The goal of this program is to understand integrative functions of the brain. This is accomplished by establishing which brain oscillations are recruited, at which times they do appear and vanish, and which large-scale coordination mechanisms bind them together. To reach solid conclusions in our empirical studies, we have also established methods that avoid the pitfalls of volume conduction and separate true and false large-scale synchrony [learn more].
