摘要: Used clinically since Penfield and Jasper's pioneering work in the 1950's, electrocorticography (ECoG) has recently been investigated as a promising technology for brain-computer interfacing. Many researchers have attempted to analyze properties of ECoG recordings, including prediction optimal electrode spacing improved resolution expected with smaller electrodes. This applies an analytic model volume conductor investigate sensitivity field electrodes various sizes. The benefit spatial was minimal than ∼1mm, while caused dramatic decrease signal-to-noise ratio. temporal correlation between pairs is predicted over range spacings compared values from series recordings subjects undergoing monitoring intractable epilepsy. observed correlations are found be much higher by suggest more detailed cortical activity needed identify appropriate grid spacing.
