“…Other studies removed the DBS artefact successfully by using spatial filters (Mäkelä et al, 2007;Airaksinen et al, 2011Airaksinen et al, , 2012Airaksinen et al, , 2015Ramírez et al, 2011;Oswal et al, 2015). While all these approaches have helped to minimize the effect of the DBS artefact, there is still a demand for an artefact rejection approach which enables retrieving oscillatory activity in different frequency ranges.…”
