Multiple neuronal networks mediate sustained attention
(MIT Press, 2003)& Sustained attention def icits occur i n several neuropsychi- atric di sorders. However, the underlying neurobiol ogical mechani sms are stil l i ncompletely understood. To that end, f unctional MRI was used to ... -
Cingulate hypoactivity in cocaine users during a GO/NOGO task as revealed by event-related fMRI.
(Society for Neuroscience, 2003)Although extensive evidence exists for the reinforcing properties of drugs of abuse such as cocaine, relatively less research has addressed the functional neuroanatomical correlates of the cognitive sequelae of these ... -
Predicting success: The effect of pre-target cueing on inhibition performance.
(MIT Press, 2004)The present study investigated the relationships between attention and other preparatory processes prior to a response inhibition task and the processes involved in the inhibition itself. To achieve this, a mixed ... -
A pattern recognition approach to the detection of single-trial event-related fMRI.
(IFMBE, 2004)Functional magnetic resonance imaging (FMRI) is an imaging technique for determining which regions of the brain are activated in response to a stimulus or event. Early FMRI experiment paradigms were based upon those ... -
Executive `brake failure? following deactivation of human frontal lobe
(MIT Press, 2006)In the course of daily living, humans frequently encounter situations in which a motor activity, once initiated, becomes unnecessary or inappropriate. Under such circumstances, the ability to inhibit motor responses ... -
The Anterior Cingulate and Error Avoidance
(Society for Neuroscience, 2006)The precise role of the anterior cingulate cortex in monitoring, evaluating, and correcting behavior remains unclear despite numerous theories and much empirical data implicating it in cognitive control. The present ... -
Automaticity and re-establishment of executive control, an fMRI study
(MIT Press, 2006)The ability to exert control over automatic behavior is of particular importance as it allows us to interrupt our behavior when the automatic response is no longer adequate or even dangerous. However, despite the ... -
Neural processing of Spatial Information: What we know about Place cells and what they can tell us about Presence.
(MIT Press, 2006)Brain processing of spatial information is a very prolific area of research in neuroscience. Since the discovery of place cells (PCs)(O'Keefe & Dostrovsky, "The hippocampus as a spatial map," Brain Research 34, 1971) ... -
A selective effect of parietal damage on letter identification in mixed case words.
(Elsevier, 2007)We investigated the reading of cAsE mIxInG and contrast reduction on word reading in patients with unilateral parietal lesions and attentional deficits. We show that, compared with control participants, the patients produce ... -
Case mixing and the right parietal cortex: evidence from rTMS.
(Springer, 2006)We investigated the necessary role of the right parietal lobe in visual word recognition using transcranial magnetic stimulation (TMS). TMS was applied to the right posterior parietal lobe and to a control area as participants ... -
The "special effect" of case mixing on word identification: neuropsychological and transcranial magnetic stimulation studies dissociating case mixing from contrast reduction
(MIT Press, 2006)We present neuropsychological evidence and evidence from transcranial magnetic stimulation (TMS) with normal readers, that the effects of case mixing and contrast reduction on word identification are qualitatively different. ... -
Dissociation in response to methylphenidate on response variability in a group of medication naïve children with ADHD
(2008)Increased variability in reaction time (RT) has been proposed as a cardinal feature of attention deficit hyperactivity disorder (ADHD). Increased variability during sustained attention tasks may reflect inefficient ... -
Regional specificity and practice: Dynamic changes in object and spatial working memory
(Elsevier, 2007)Working memory (WM) tasks engage a network of brain regions that includes primary, unimodal, and multimodal associative cortices. Little is known, however, about whether task practice influences these types of regions ... -
Response variability in Attention Deficit Hyperactivity Disorder: evidence for neuropsychological heterogeneity
(2007)Response time (RT) variability is a common finding in ADHD research. RT variability may reflect frontal cortex function and may be related to deficits in sustained attention. The existence of a sustained attention deficit ... -
Dissociation in performance of children with ADHD and autism on a task of sustained attention
(2007)Attention deficit hyperactivity disorder (ADHD) and autism are two neurodevelopmental disorders associated with prominent executive dysfunction, which may be underpinned by disruption within fronto-striatal and fronto-parietal ... -
Association between dopamine transporter (DAT1) genotype, left-sided inattention, and an enhanced response to methylphenidate in attention deficit hyperactivity disorder (ADHD)
(2005)A polymorphism of the dopamine transporter gene (DAT1, 10-repeat) is associated with ADHD and has been linked to an enhanced response to methylphenidate (MPH). One aspect of the attention deficit in ADHD includes a subtle ... -
Rehabilitation of executive functioning: An experimental?clinical validation of Goal Management Training
(2000)Two studies assessed the effects of a training procedure (Goal Management Training, GMT), derived from Duncan?s theory of goal neglect, on disorganized behavior following TBI. In Study 1, patients with traumatic brain ...
