Methylphenidate selectively modulates one sub-component of the no-go P3 in pediatric ADHD medication responders
Brunner, Ida Emilia; Øgrim, Kjell Geir; Kropotov, Juri D; Brunner, Jan Ferenc (Journal article; Peer reviewed, 2018)Methylphenidate (MPH) has been shown to modulate the amplitude of the no-go P3 component of the event-related potential (ERP; Øgrim, Aasen, & Brunner, 2016). Using group independent component analysis, the no-go P3 from a ... -
