Changes in resting connectivity with age: A simultaneous electroencephalogram and functional magnetic resonance imaging investigation.
O'CONNELL, REDMOND; ROBERTSON, IAN; BOKDE, ARUN; NOLAN, HUGH (2013)Resting fluctuations in the blood oxygenation level-dependent signal have attracted considerable interest for their sensitivity to pathological brain processes. However, these analyses are susceptible to confound by nonneural ... -
Decreased frontal, striatal and cerebellar activation in adults with ADHD during an adaptive delay discounting task
WHELAN, ROBERT; GARAVAN, HUGH; O'CONNELL, REDMOND (2015)An important characteristic of childhood attention-deficit/hyperactivity disorder (ADHD) is a bias towards small immediate versus larger delayed rewards, but it is not known if this symptom is also a feature of adult ADHD. ... -
The effects of a self-alert training (SAT) program in adults with ADHD
ROBERTSON, IAN; O'CONNELL, REDMOND (2015)Attention-Deficit/Hyperactivity Disorder (ADHD), a neuropsychiatric condition characterized by attention and impulsivity problems, is one of the most common behavioral disorders. The first line of treatment for ADHD is ... -
Linking time-on-task, spatial bias and hemispheric activation asymmetry: a neural correlate of rightward attention drift.
O'CONNELL, REDMOND (2013)Biases of spatial attention may be moderated by non-spatial factors such as attentional load and time-on-task. Although these effects are thought to arise from depletion of right hemisphere processing resources, their ... -
Neural evidence accumulation persists after choice to inform metacognitive judgments.
ROBERTSON, IAN; O'CONNELL, REDMOND (2015)The ability to revise one's certainty or confidence in a preceding choice is a critical feature of adaptive decision-making but the neural mechanisms underpinning this metacognitive process have yet to be characterized. ... -
Neurochemical enhancement of conscious error awareness.
O'CONNELL, REDMOND (2012)How the brain monitors ongoing behavior for performance errors is a central question of cognitive neuroscience. Diminished awareness of performance errors limits the extent to which humans engage in corrective behavior and ... -
Ocular exposure to blue-enriched light has an asymmetric influence on neural activity and spatial attention
O'CONNELL, REDMOND (2016)Brain networks subserving alertness in humans interact with those for spatial attention orienting. We employed blue-enriched light to directly manipulate alertness in healthy volunteers. We show for the first time that ... -
The role of Cingulate Cortex in the detection of errors with and without awareness: a high-density electrical mapping and source-analysis study
O'CONNELL, REDMOND; ROBERTSON, IAN; GARAVAN, HUGH PATRICK; DOCKREE, PAUL MICHAEL; FOXE, JOHN (2007) -
Target selection signals influence perceptual decisions by modulating the onset and rate of evidence accumulation
O'CONNELL, REDMOND; LALOR, EDMUND (2016)
