摘要： An apparatus comprises a data processing unit, which causes the apparatus to: receive at least two electroencephalographic signals of a brain of a person; form a first information about at least one of the following: phase-to-phase coupling between at least two electroencephalographic signals, phase-to-amplitude coupling between at least two electroencephalographic signals and amplitude-to-phase coupling between at least two electroencephalographic signals, the first information being related to slow waves having frequencies at or lower than 1 Hz; normalize the first information; and output information about the normalized first information.

摘要： A method of forming modifying data related to a data sequence for a data frame including electroencephalogram data where the modifying data is formed by selecting: one sequence from at least one surrogate data sequence for a neutral data sequence that is for replacing a missing or corrupted data sequence of the electroencephalogram data, or a surrogate algorithm, which is for generating at least one surrogate data sequence, which includes the neutral data sequence. The selection is based on an optimization comparison between a first data and a second data in order to limit disturbance caused in case the neutral data sequence is applied to the data frame. The first data comprises reference data or a reference algorithm for generating the reference data. The second data comprises at least one result formed by applying a result algorithm, which provides characterizing information on the data frame including the electroencephalogram data, to the electroencephalogram data with the at least one surrogate data sequence replacing the missing or corrupted data sequence of the electroencephalogram data, or the result algorithm based on the electroencephalogram data and the surrogate algorithm.
