Error-related electrocortical responses in 10-year-old children and young adults.

Developmental differences in the ERN, Pe, and CRN in normal 10-year-old children and young adults in a standard visual flanker task are examined and provide electrophysiological support either for late maturation of the ACC or late involvement of theACC in response monitoring.

Electrophysiology of Oculomotor Delayed Response Tasks: A Model for the Maturation of Visual-Spatial Working Memory Networks

Neural functioning underlying visual-spatial WM differed between age groups in the Match condition and was localized anteriorly during the late delay period, which may indicate that adolescents and young adults may recruit frontal-parietal resources differently.

Electrophysiological and behavioral indices of cognitive conflict processing across adolescence

Charting functional brain development in adolescence with electrophysiology: Links with behavior and cortical structure

It is suggested that the age differences in component strength reflect development of attentional mechanisms, with increased brain responses to task-relevant stimuli representing an increasing ability to focus on relevant information and to respond accurately and efficiently.

Sex Differences in Brain Maturation as Measured Using Event-Related Potentials

Sex differences in the maturation of event-related potential (ERP) amplitudes during an auditory oddball task are investigated, demonstrating sex differences in ERP maturation in line with behavioral and neuroimaging studies.

Changes of brain activity in the neural substrates for theory of mind during childhood and adolescence

It is considered that the age‐related brain activity observed in the present study may be associated with the maturation of the prefrontal cortex and the associated development of cognitive functions.

Developmental Trajectories of Neural Mechanisms Supporting Conflict and Error Processing in Middle Childhood

To study age-related changes in cognitive control, event-related potentials of children aged 6–9 years, 10–12 years, and young adults were recorded during a Flanker task to indicate dissociable maturational time tables of subdivisions of the anterior cingulate cortex.



CNV evidence for the distinctiveness of frontal and posterior neural processes in a traumatic brain-injured population.

Three of the four executive function tests were significantly related to the Contingent Negative Variation task, a proposed electrophysiological index of frontal-lobe functioning, and the CNV did not correlate at all with the posterior tasks.

Cleverness and wisdom in 12‐year‐olds: Electrophysiological evidence for late maturation of the frontal lobe

We were interested in the degree to which neuropsychological indices of frontal lobe function could account for individual differences as well as matura‐tional aspects of cognitive development.

Brain activity and cognitive transition during childhood: A longitudinal event-related brain potential study.

This study examined the relation between brain activation and cognitive development using event-related brain potentials (ERPs) and a longitudinal design. Five-year-old girls performed a visual

Scalp topography of event-related brain potentials and cognitive transition during childhood.

It is concluded that ERPs may provide a window on the relation between brain maturation and stage-wise cognitive development and topographic and symmetric dipole analyses of the ERPs suggested more anterior ERP sources for the nonconservers during the early part of stimulus analysis and more lateralized ERPs for conservers During the later part of information processing.

Role of prefrontal cortex in generation of the contingent negative variation.

The CNV findings coupled with behavioral evidence of impaired preparatory processes in these patients support the role of PFCx in sustaining distributed neural activity during delay periods.

Action-Monitoring Dysfunction in Obsessive-Compulsive Disorder

Electrophysiological evidence is reported suggesting that part of a hyperactive frontal-striatal-thalamic-frontal circuit is associated with the symptoms of obsessive-compulsive disorder and part of this system monitors events and generates error signals when the events conflict with an individual's internal standards or goals.

Effects of age on the P300 component of the event-related potential from auditory stimuli: peak definition, variation, and measurement.

Previous age-related ERP changes were confirmed and extended to the P3a and P3b subcomponents of the P300 and P300 latency variability also was found to increase somewhat with advanced age.
