Tracking the functional development of specific regions of the prefrontal cortex in children using event-related potentials (ERPs) is challenging for both technical and conceptual reasons. In this paper we outline our strategy for studying frontal lobe development and present preliminary results from children aged 7-17 years and young adults using ERPs functionally associated with anterior cingulate and prefrontal cortex, especially the orbitofrontal, ventral, and medial portions. Our analysis… Expand
Error-related electrocortical responses in 10-year-old children and young adults.
TLDR
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. Expand
Electrophysiology of Oculomotor Delayed Response Tasks: A Model for the Maturation of Visual-Spatial Working Memory Networks
In the literature, persistent neural activity over frontal and parietal areas during the delay period of oculomotor delayed response (ODR) tasks has been interpreted as an active representation ofExpand
The role of cognitive event‐related potentials in executive dysfunction
TLDR
The findings suggest that patients with FLL may have prolonged P300 latency, which has a good correlation with executive dysfunction, poor performance, and longer P300 latencies. Expand
Development of orbitofrontal function: Current themes and future directions
TLDR
This special issue of Brain and Cognition is intended to redress this imbalance by bringing together researchers who are studying the nature and development of orbitofrontal function from a wide variety of perspectives. Expand
Electrophysiological and behavioral indices of cognitive conflict processing across adolescence
TLDR
A multifaceted developmental pattern in neurocognitive mechanisms for conflict processing across adolescence is suggested, with a more protracted development of the parietal positive compared to the frontal negative component. Expand
Charting functional brain development in adolescence with electrophysiology: Links with behavior and cortical structure
Maturation of attentional processes is central to cognitive development. The electrophysiological P300 is associated with rapid allocation of attention, and bridges stimulus and response processing.Expand
Sex Differences in Brain Maturation as Measured Using Event-Related Potentials
TLDR
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. Expand
Neural correlates of cognitive control in childhood and adolescence: Disentangling the contributions of age and executive function
TLDR
It is suggested that age-related decreases in N2 amplitude, but not N2 latency, reflect the development of cognitive control and cannot be attributed solely to incidental changes that may affect assessments of the N2 (e.g., increases in skull thickness). Expand
Changes of brain activity in the neural substrates for theory of mind during childhood and adolescence
TLDR
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. Expand
Developmental Trajectories of Neural Mechanisms Supporting Conflict and Error Processing in Middle Childhood
TLDR
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. Expand

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

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.Expand
P3 topographical change with task familiarization and task complexity.
TLDR
The results are interpreted as indicating rapid decrease in initial P3 hyperfrontality for a simple task in young adults, and an increased ratio of P3 amplitude at frontal versus posterior sites in more complex tasks. Expand

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 visualExpand
Immature Frontal Lobe Contributions to Cognitive Control in Children Evidence from fMRI
TLDR
Children exhibited immature prefrontal activation that varied according to the type of cognitive control required, and were more susceptible to interference and less able to inhibit inappropriate responses than were adults. Expand
Scalp topography of event-related brain potentials and cognitive transition during childhood.
TLDR
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.

Error detection in patients with lesions to the medial prefrontal cortex: an ERP study
TLDR
It is shown that subjects can be aware of errors and yet not produce an Ne/ERN, suggesting that error detection may be supported by circuits outside the anterior cingulate region. Expand
Role of prefrontal cortex in generation of the contingent negative variation.
TLDR
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. Expand
Action-Monitoring Dysfunction in Obsessive-Compulsive Disorder
TLDR
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.
TLDR
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. Expand
