Abstract (en)
[origin: WO2015177080A1] The invention specifies a method and an associated arrangement for increasing the signal-to-noise ratio of evoked potential signals and event-related potential signals of a neuronal activity. The method comprises the following steps: – transforming single sweep signals of the neuronal activity for obtaining current phases of the single sweep signals from an original time interval, – providing a time representation of the current phases in a 2D single sweep matrix, – changing the current phases in such a way that the circular variance along at least one phase track in the 2D single sweep matrix is reduced, and – performing a back transformation with the modified current phases into the original time interval for forming phase-regularized single sweep signals. The invention offers the advantage that the signal-to-noise ratio of evoked potential signals and event-related potential signals of a neuronal activity is significantly improved by the phase regularization.
