Abstract: The human brain consists of numerous networks distributed over space and connected over time that orchestrate behavior and meaningful interaction with the external world. The emergence of advanced methods for recording and interpreting signals from the surface of the brain (electrocorticography (ECoG)) has opened up exciting new opportunities for studying brain function during behavior. These developments have sparked tremendous interest in utilizing human ECoG in systems neuroscience, clinical assessment of brain function, and for the design of neural interfaces. In this talk, I will describe the nature of these cortical surface potentials and how they facilitate the investigation of widely spread behavioral networks with high temporal resolution. I will then demonstrate that ECoG encodes detailed aspects of motor behavior, auditory perception, auditory and visual spatial attention, and language. I will also discuss the potential translational applications of these findings and the future directions of this relatively new, but thriving, field of ECoG research in humans.
