“…In this context, it is relevant to mention reported working memory deficits in children with ADHD (Nikolas and Nigg, 2013). Working memory crucially depends on theta oscillation (Billeke et al, 2017;Larrain-Valenzuela et al, 2017;Figueroa-Vargas et al, 2020), and its impairment can preclude the adequate information maintaining necessary to exert general proactive cognitive control. In a broad sense, these functional results can be related to the functional differences observed in children with ADHD in prefrontal areas when compared to TD children (Nakao et al, 2011;Frodl and Skokauskas, 2012) and the difference between TD children according to age (Bruin et al, 2001;Jonkman, 2006;Spronk et al, 2008).…”
