Figure 8. An EEG study showing differences in post-cue alpha suppression, a marker of visual cue processing, in individuals with ADHD and typically developing children.

Figure 8

Adolescents with ADHD (especially the inattentive (IA) subtype) showed reduced occipital alpha suppression following response-preparation cues, reflecting weaker engagement of visual attentional mechanisms. A) The topography of post-cue alpha reduction across all groups. B) The cue-locked time-frequency spectra at occipital electrode Oz. C) The time course of alpha activity, with typically developing (TD) adolescents exhibited the strongest suppression in the 0–500 ms window, and IA adolescents the weakest. These oscillatory patterns align with broader findings that ADHD subtypes show distinct neural signatures, with IA displaying impaired visual cue processing and both subtypes showing altered top-down control.
