Research scientists in neuropsychiatry tend to be nonselective and non concept-oriented in using only one of the methods from the ensemble of oscillatory analyses. Consequently, brain oscillations often fail to provide useful and effective results in terms of biomarker identification or cognitive deficiency screening. This paper has suggested ways of improving such analyses by emphasizing the complementarity - between the different methods of brain oscillation investigation and the overriding need to use them in combination with one another.
