We compared brain activity (electroencephalography) during a same-different task for High and Low AQ groups. The task was composed of identical comparison and categorical comparison (CC) conditions that presented simple or complex patterns. In the CC condition, the Low AQ showed large P3b amplitudes with simple patterns than with complex patterns, whereas the High AQ showed the same amplitude levels for these patterns. These indicate that, similar to simple patterns, complex patterns are efficiently encoded in the High AQ. Moreover, the High AQ had no impairment in the global pattern encoding compared with the Low AQ.

The N170 event-related potential reflects delayed neural response to faces when visual attention is directed to the eyes in youths with ASD / Termara PARKER in Autism Research, 14-7 (July 2021)  

Public ISBD [article]  inAutism Research > 14-7 (July 2021) . - p.1347-1356 Titre : The N170 event-related potential reflects delayed neural response to faces when visual attention is directed to the eyes in youths with ASD Type de document : texte imprimé Auteurs : Termara PARKER, Auteur ; Michael J. CROWLEY, Auteur ; Adam J. NAPLES, Auteur ; Max J. ROLISON, Auteur ; Jieling WU, Auteur ; Julie A. TRAPANI, Auteur ; James C. MCPARTLAND, Auteur Article en page(s) : p.1347-1356 Langues : Anglais (eng) Mots-clés : Adolescent  Autism Spectrum Disorder  Brain  Child  Evoked Potentials  Facial Recognition  Humans  Eeg  N170  autism  event-related potential  face perception  social neuroscience Index. décimale : PER Périodiques Résumé : Atypical neural response to faces is thought to contribute to social deficits in autism spectrum disorder (ASD). Compared to typically developing (TD) controls, individuals with ASD exhibit delayed brain responses to upright faces at a face-sensitive event-related potential (ERP), the N170. Given observed differences in patterns of visual attention to faces, it is not known whether slowed neural processing may simply reflect atypical looking to faces. The present study manipulated visual attention to facial features to examine whether directed attention to the eyes normalizes N170 latency in ASD. ERPs were recorded in 30 children and adolescents with ASD as well as 26 TD children and adolescents. Results replicated prior findings of shorter N170 latency to the eye region of the face in TD individuals. In contrast, those with ASD did not demonstrate modulation of N170 latency by point of regard to the face. Group differences in latency were most pronounced when attention was directed to the eyes. Results suggest that well-replicated findings of N170 delays in ASD do not simply reflect atypical patterns of visual engagement with experimental stimuli. These findings add to a body of evidence indicating that N170 delays are a promising marker of atypical neural response to social information in ASD. LAY SUMMARY: This study looks at how children's and adolescents' brains respond when looking at different parts of a face. Typically developing children and adolescents processed eyes faster than other parts of the face, whereas this pattern was not seen in ASD. Children and adolescents with ASD processed eyes more slowly than typically developing children. These findings suggest that observed inefficiencies in face processing in ASD are not simply reflective of failure to attend to the eyes.

Increased reaction time variability in attention-deficit hyperactivity disorder as a response-related phenomenon: evidence from single-trial event-related potentials / Christopher W.N. SAVILLE in Journal of Child Psychology and Psychiatry, 56-7 (July 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-7 (July 2015) . - p.801-813 Titre : Increased reaction time variability in attention-deficit hyperactivity disorder as a response-related phenomenon: evidence from single-trial event-related potentials Type de document : texte imprimé Auteurs : Christopher W.N. SAVILLE, Auteur ; Bernd FEIGE, Auteur ; Christian KLUCKERT, Auteur ; Stephan BENDER, Auteur ; Monica BISCALDI, Auteur ; Andrea BERGER, Auteur ; Christian FLEISCHHAKER, Auteur ; Klaus HENIGHAUSEN, Auteur ; Christoph KLEIN, Auteur Article en page(s) : p.801-813 Langues : Anglais (eng) Mots-clés : ADHD  EEG  reaction time  working memory  event-related potential Index. décimale : PER Périodiques Résumé : Background Increased intra-subject variability (ISV) in reaction times (RTs) is a promising endophenotype for attention-deficit hyperactivity disorder (ADHD) and among the most robust hallmarks of the disorder. ISV has been assumed to represent an attentional deficit, either reflecting lapses in attention or increased neural noise. Here, we use an innovative single-trial event-related potential approach to assess whether the increased ISV associated with ADHD is indeed attributable to attention, or whether it is related to response-related processing. Methods We measured electroencephalographic responses to working memory oddball tasks in patients with ADHD (N = 20, aged 11.3 ± 1.1) and healthy controls (N = 25, aged 11.7 ± 1.1), and analysed these data with a recently developed method of single-trial event-related potential analysis. Estimates of component latency variability were computed for the stimulus-locked and response-locked forms of the P3b and the lateralised readiness potential (LRP). Results ADHD patients showed significantly increased ISV in behavioural ISV. This increased ISV was paralleled by an increase in variability in response-locked event-related potential latencies, while variability in stimulus-locked latencies was equivalent between groups. This result held across the P3b and LRP. Latency of all components predicted RTs on a single-trial basis, confirming that all were relevant for speed of processing. Conclusions These data suggest that the increased ISV found in ADHD could be associated with response-end, rather than stimulus-end processes, in contrast to prevailing conceptions about the endophenotype. This mental chronometric approach may also be useful for exploring whether the existing lack of specificity of ISV to particular psychiatric conditions can be improved upon.

Assessing the integrity of auditory sensory memory processing in CLN3 disease (Juvenile Neuronal Ceroid Lipofuscinosis (Batten disease)): an auditory evoked potential study of the duration-evoked mismatch negativity (MMN) / Tufikameni BRIMA in Journal of Neurodevelopmental Disorders, 16 (2024)

Index. décimale : PER Périodiques Résumé : BACKGROUND: We interrogated auditory sensory memory capabilities in individuals with CLN3 disease (juvenile neuronal ceroid lipofuscinosis), specifically for the feature of "duration" processing. Given decrements in auditory processing abilities associated with later-stage CLN3 disease, we hypothesized that the duration-evoked mismatch negativity (MMN) of the event related potential (ERP) would be a marker of progressively atypical cortical processing in this population, with potential applicability as a brain-based biomarker in clinical trials. METHODS: We employed three stimulation rates (fast: 450 ms, medium: 900 ms, slow: 1800 ms), allowing for assessment of the sustainability of the auditory sensory memory trace. The robustness of MMN directly relates to the rate at which the regularly occurring stimulus stream is presented. As presentation rate slows, robustness of the sensory memory trace diminishes. By manipulating presentation rate, the strength of the sensory memory trace is parametrically varied, providing greater sensitivity to detect auditory cortical dysfunction. A secondary hypothesis was that duration-evoked MMN abnormalities in CLN3 disease would be more severe at slower presentation rates, resulting from greater demand on the sensory memory system. RESULTS: Data from individuals with CLN3 disease (N = 21; range 6-28 years of age) showed robust MMN responses (i.e., intact auditory sensory memory processes) at the medium stimulation rate. However, at the fastest rate, MMN was significantly reduced, and at the slowest rate, MMN was not detectable in CLN3 disease relative to neurotypical controls (N = 41; ages 6-26 years). CONCLUSIONS: Results reveal emerging insufficiencies in this critical auditory perceptual system in individuals with CLN3 disease.

The error-related negativity (ERN) is an event-related potential elicited when people make mistakes on simple laboratory-based reaction time tasks that has been associated with risk for anxiety. This study examined whether the ERN prospectively predicted the first onset of generalized anxiety disorder (GAD) over 1.5 years in adolescent girls. METHODS: The sample included 457 girls between the ages of 13.5 and 15.5 years, with no history of GAD. At baseline, the ERN was measured using a flankers task. Psychiatric history of the adolescent and biological parent was assessed with diagnostic interviews, and the adolescent completed a self-report questionnaire regarding anxiety symptoms. Approximately 1.5 years later, adolescents completed the same interview. RESULTS: An increased neural response to errors at baseline predicted first-onset GAD over 1.5 years. The ERN was a significant predictor independent of other prominent risk factors, including baseline anxiety and depression symptoms and parental lifetime psychiatric history. Jointly the ERN and social anxiety symptoms provided the greatest power for predicting first-onset GAD. CONCLUSIONS: This study provides evidence for the utility of the ERN as a biomarker of risk for GAD during a key developmental period.
