Proceedings of the Fourth International Workshop on Advances in Electrocorticography

• Basic research suggests that ECoG can elucidate brain function in ways that cannot be readily achieved using other imaging modalities.
• Translational research is producing ECoG-based applications that are beginning to be available in the clinic.
• There is great potential for continuing improvements in signal acquisition, signal analysis, and interpretation of ECoG signals.
• ECoG is increasingly recognized for its important value in characterizing normal and abnormal brain functions.

The Fourth International Workshop on Advances in Electrocorticography (ECoG) convened in New Orleans, LA, on October 11–12, 2012. The proceedings of the workshop serves as an accurate record of the most contemporary clinical and experimental work on brain surface recording and represents the insights of a unique multidisciplinary ensemble of expert clinicians and scientists. Presentations covered a broad range of topics, including innovations in passive functional mapping, increased understanding of pathologic high-frequency oscillations, evolving sensor technologies, a human trial of ECoG-driven brain–machine interface, as well as fresh insights into brain electrical stimulation.
