Gabrielli, 1995; Rangaswamy et al., 2004), although the specific beta frequencies involved and their scalp topographies have been shown to differ as a function of gender (Rangaswamy et al., 2002; 2004). Beta power has been shown to be reduced, however, in adolescents with ADHD (Hobbs, Clarke, Barry, McCarthy, & Selikowitz, 2007; Mann, Lubar, Zimmerman, Miller, & Muenchen, 1992), ADHD with comorbid oppositional defiant disorder (Clarke, Barry, McCarthy, & Selikowitz, 2002), and young adults exhibiting impulsive and antisocial personality characteristics (Houston & Stanford, 2005). Further, while boys’ beta power is reduced more than that of girls relative to controls (Clarke, Barry, McCarthy, & Selikowitz, 2001), girls with ADHD show reduced beta more consistently (i.e. with less variability) than boys (Clarke et al., 2003).
