Large Scale Brain Dynamics (Part 1)

The "Large Scale Brain Dynamics" workshop is focused on the dynamics of electrical activity of the brain on the 5-10 mm scale, with an emphasis on multielectrode electrocorticographic (ECoG) recording. Central questions include: What are the relevant aspects of the large scale cortical signal for feature extraction? Given current clinical technology, what constraints are there on the large scale potential measurements at the brain surface? (That is, is there a cutoff frequency for signal extraction? How reproducible are phenomena? What is the true temporal, spatial, and spectral fidelity?) If two cortical areas are communicating, what sort of ECoG signal features would be present? What is the best way to track variable-delay activity in multiple brain regions associated with a complex task? The primary goal of the workshop is to provide a forum to identify and discuss the key issues of the field.
