Event-Related Potential Analysis of ADHD and Control Adults During a Sustained Attention Task
TLDR
Findings of reduction in N1, N2 and P3 components highlight deficits of early sensory processing, stimulus categorization, and attentional resources, respectively, in adults with ADHD.
Developmental event‐related gamma oscillations: effects of auditory attention
TLDR
The results indicate that specific aspects of task‐stimulus processing engage distinct spatially localized gamma networks at functionally relevant areas, and the neuronal substrates of gamma band networks and the ability to synchronize them in relation to task‐specific processes are available in all age groups from 9 to 16 years.
Early Gamma-Band Activity During Interference Predicts Working Memory Distractibility in ADHD
TLDR
The data suggest that ADHD patients are disturbed by interference on an early level of perception.
EEG Dynamics of a Go/Nogo Task in Children with ADHD
TLDR
Impaired ability in children with ADHD to conserve the brain oscillations phase associated with stimulus processing is suggested to serve as a target for therapeutic intervention or be used as monitoring of their effects.

A bimodal neurophysiological study of motor control in attention-deficit hyperactivity disorder: a step towards core mechanisms?
TLDR
Findings indicate deviant neural implementation of motor control in children with attention-deficit hyperactivity disorder reflecting compensatory cognitive mechanisms as a result of a basal motor cortical inhibitory deficit (reduced activation of inhibitory intracortical interneurons).

Gamma band response in children is related to task‐stimulus processing
TLDR
The functional characteristics of early phase-locked electroencephalographic gamma band responses in 9- to 12-year-old healthy children demonstrate that the auditory GBR is related to task-stimulus processing and imply that early target selection in children is guided by a sensory or sensorimotor preparatory set, rather than by an internal attentional focus to the side of stimulation.
Spatial orienting and focused attention in attention deficit hyperactivity disorder.
TLDR
Performance was similar for both groups, but the early portion of P3 was lower in amplitude for invalidly cued targets in ADHD subjects and MP increased accuracy without affecting RT and shortened P3 peak latency and increased the amplitude of its early portion.
Developmental changes in the theta response system: a single-sweep analysis
Recently, increased interest was focused on the EEG frequency responses in the theta (4-7 Hz) range because of their association with stimulus information processing. However, it is not known whether
