Microstates in Electrocorticography


Microstates are thought to represent ~10-100ms periods of coordinated neuronal activity by some subset of generators in the brain.  These periods are identified in electrocordicography data by modeling the resultant quasi-stable voltage topographies and deriving feature patterns similar to those originating from full-scalp EEG analysis. The results indicate that distinct neural states can be accurately modeled by microstates and that these models are consistent across multiple spatial scales.
