Event-related potentials and performance of attention-deficit hyperactivity disorder: Children and normal controls in auditory and visual selective attention tasks

TL;DR: Attention-deficit hyperactivity disorder (ADHD) children and normal controls (7-13 yrs old) performed an auditory and visual selective attention task and hypothesized that in ADHD children in both the auditory and the visual task, there is a deficit in the activation of the P3b process.
Journal ArticleDOI
Is the early modulation of brain activity by fearful facial expressions primarily mediated by coarse low spatial frequency information
TL;DR: The findings clearly show that fearful facial expressions increases the amplitude of P1 and N170 in comparison to neutral faces but only in LSF faces, irrespective of contrast or luminance equalization, further suggesting that LSF information plays a crucial role in the early brain responses to fear.
Journal ArticleDOI
Associations between event-related potentials and measures of attention and inhibition in the Continuous Performance Task in children with ADHD and normal controls
C.C.E. Overtoom,Marinus N. Verbaten,Chantal Kemner,J. Leon Kenemans,Herman van Engeland,Jan K. Buitelaar,G. Camfferman,Harry S. Koelega +7 more
TL;DR: The ADHD group studied showed deficits in attention but not in impulsivity (or inhibition) and a subgroup of children with ADHD and oppositional defiant disorder had smaller N2 waves than controls, however.
Journal ArticleDOI
Looking at images with human figures: comparison between autistic and normal children.
TL;DR: The results do not support the notion that autistic children have a specific problem in processing socially loaded visual stimuli and suggest that the often-reported abnormal use of gaze in everyday life is not related to the nature of the visual stimuli but that other factors, like social interaction, may play a decisive role.
Journal ArticleDOI
Effects of methylphenidate, desipramine, and L-dopa on attention and inhibition in children with Attention Deficit Hyperactivity Disorder.
C.C.E. Overtoom,Marinus N. Verbaten,Chantal Kemner,J.L. Kenemans,H. van Engeland,Jan K. Buitelaar,M.W. van der Molen,J. van der Gugten,Herman G.M. Westenberg,Robert A. A. Maes,Harry S. Koelega +10 more
TL;DR: It is suggested that the effects of MPH on attention are due to a combination of noradrenergic and dopaminergic mechanisms, and improved inhibition under DMI could be serotonergically mediated.
