Subject: Shifting attention to dynamics: Self-reconfiguration of neural networks

In recent years, considerable evidence has accrued indicating that brain function can be flexibly reconfigured on the fly: certain brain areas are capable of carrying out a variety of different functions and are able to switch between those functions in a context-sensitive, dynamic fashion. Some evidence has also emerged that ongoing brain activity, the ceaseless background brain dynamics, may be implicated in setting and controlling these dynamic functions as well as attentional gain control. A crucial link between them is dynamics. I will discuss both the accumulating evidence as well as a theoretical outline of dynamical mechanisms for functional self-reconfiguration of neural networks, including reconfiguration of logic function, reconfiguration of information routing, and poising at critical points to reconfigure dynamics.
