A study of event-related electrocortical oscillatory dynamics associated with cued motor-response inhibition during performance of the Go/NoGo task within a sample of prenatally alcohol-exposed children and age-matched controls
… from Cape Town, South Africa, performing the Go/NoGo response inhibition task. We utilised event-related electroencephalographic methodologies to examine event-related potentials (ERP) and eventrelated changes in induced oscillatory power - event-related desynchronisation (ERD)/eventrelated …

Bedeutung von Elektrodenzahl und anderer Parameter bei dreidimensionaler Quellenlokalisation (LORETA) in ereigniskorrelierten Potenzialen
… durch Tests wie den Continuous Performance Test (Go-Nogo-Paradigma) ausgelöst werden. Um für die Identifikation unterschiedlicher aktivierter Areale im Gehirn die hohe zeitliche Auflösung EEG-basierter Daten nutzen zu können, benötigt man ein Verfahren zur dreidimensionalen Quellenlokalisation. …

Mind, Body and Race: A Look Into How Racial Biases and Interoceptive Cues Influence Emotion Perception
… part in this study and completed an emotional Go/NoGo task in which they were asked to categorize different race faces as portraying either anger or fear. While participants completed the task, electromyography (EMG) activity of the Corrugator Supercilli muscle was measured. Results indicated …

Cerebrale Korrelate der selektiven Aufmerksamkeit bei schizophrenen Patienten mit formalen Denkstörungen : eine kontrollierte H2 15O-PET-Studie
… measuring alertness and selective attention (Go/NoGo) served as stimulation paradigm and reference paradigm for the assessment of the rCBF, using H215O-PET. While the first hypothesis has not been confirmed, we found that the cerebral regions activated by selective attention in both clinical …

Heterogeneity in hyperkinetic disorder
… Automated Battery (CANTAB) and a computerised Go/NoGo task in a large well described group of boys with rigorously diagnosed HKD who were stimulant medication naïve at baseline, it was demonstrated that the neuropsychological heterogeneity in the HKD boys was very similar to that seen …

Conflict and adaptation: Identifying the markers of cognitive control in the transition from wakefulness to sleep
… top-down behavioural control. Using a combined Go/NoGo and Go-left/Go-right paradigm, we investigated effects of alertness on reaction times and responsiveness. We revealed an interaction between the task requirement to monitor conflict (Go/NoGo) and the level of alertness. Crucially, the …

Striatal Control of Sensory-Driven Behavior and Its Relevance for Neuropsychiatric Disorders
… to sensory stimuli. Mice performed an auditory Go/NoGo task while we recorded cell-specific activity from TS neurons to identify how distinct striatal pathways contribute to sound-driven behavior. Both major striatal neuron types were active during reward-related target sounds, whereas …

Factors that influence motor performance: Colour, inhibition and conscious processing
… between inhibition function (indexed by the Go/NoGo task) and propensity for conscious control of movement (assessed by the Movement Specific Reinvestment Scale, MSRS). Experiment 3 (Chapter 4) examined the effect of colour on inhibition function during a basketball-specific Go/NoGo task. …

An Investigation into Long-Chain Polyunsaturated Essential Fatty Acids, Event Related Potential Assessments of Brain Function and Behavioural Measures in Children and Adolescents with and without Attention Deficit Hyperactivity Disorder
… task and specific P3 reduction in ADHD for the Go process of the Go/NoGo task. The performance was correlated with LC-PUFA in controls only. Associations were observed between reduced P3 and LC-PUFA in both groups, possibly suggesting enhanced neuronal efficiency. For the emotion processing …

An EEG Source-Space Analysis of the Neural Correlates Underlying Self-Regulation
… thoughts and behaviors to be aligned with our goals. This process is used in many different contexts and has been associated with contributions from several brain regions. This research aimed to investigate differences in four prefrontal areas of the brain while participants applied four …

The inefficiency of open-loop fMRI experiments
… Human Connectome Project-Aging (HCP-A) during a Go/NoGo task were also reported, along with the network's distributional effects across subjects. When examining DMN levels in 136 subjects more prone to commission errors the mean DMN levels were reported to be higher during and prior to incorrect …

Alcohol-Related Craving and Response Inhibition: Examining Effects of Mindfulness Among Binge Drinking and Cannabis Using College Students
… clip, participants (N = 30) completed a cued Go/NoGo task. EEG activity was measured throughout, and alcohol craving was assessed before and after each task. We examined whether P300 amplitude would differ as a function of the within-subjects variables Block (1 vs. 2), Target (Go vs. NoGo), …

Emotionale Modulation von Impulsivität bei Patientinnen mit Borderline Persönlichkeitsstörung
… Neutral) mit einer Impulskontrollaufgabe (Go/NoGo) verband. Neben dem Vergleich mit einer gesunden Kontrollgruppe wurden zur störungsspezifischen Abgrenzung auch Frauen mit ADHS untersucht. Patientinnen mit BPS gaben dabei in Selbstbeurteilungsmaßen höhere Impulsivitätswerte als gesunde …

Investigating the relationship between cognitive control and speech-in-noise recognition in tinnitus from perceptual, neuroanatomical, and electrophysiological aspects
… to record brain activity during Go/Nogo tasks, the third study examined whether event-related potentials related to cognitive control are associated with SiN performance in individuals with tinnitus. Results and Discussion: Overall, the findings of the three studies suggest that …

Executive functions in obsessive-compulsive disorder : a neuropsychological and event-related potential investigation
… normal control participants completed a visual go/nogo task while ERPs were recorded. Results failed to support previous observation of nogo P300 topographic differences implicating impaired response inhibition in OCD. In contrast, controls demonstrated shorter posterior N100 latency, suggesting …

Emotion Recognition, Emotion Regulation, and Callous: Unemotional Traits in Incarcerated Male Youth
… (CU) traits using an Emotional Go/Nogo task (EGNG), a measure of emotion recognition, cognitive control, and emotional regulation, with a specific focus on the recognition and regulation of responses to negative facial expressions. Participants included 268 male, sentenced or …

Early adversity and individual differences in adolescent mental health
… I first used unsupervised machine learning algorithms to identify distinct psychological subgroups of young people who self-harm. This was followed by a supervised machine learning algorithm to identify significant risk factors across a nine-year period for the different subgroups – ultimately …

Unconscious priming of "freely" chosen voluntary actions: Behavioral and electrophysiological evidence
… free-choice actions after the presentation of a Go-signal. In Experiments 2 and 3 a NoGo-signal indicating that responses had to be withheld could appear with the same likelihood as the Go-signal. Unknown to the participants, one of the former action-effects (diamond or square) was presented …
