Are auditory-evoked frequency and duration mismatch negativity (MMN) deficits endophenotypic for schizophrenia? High-density electrical mapping in clinically unaffected first-degree relatives, recent-onset and chronic schizophrenia
(Elsevier, 2008)Mismatch negativity (MMN) is a negative-going event-related potential (ERP) component that occurs in response to intermittent changes in constant auditory backgrounds. A consistent finding across a large number of studies ... -
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 ... -
Learning and memory deficits in ecstasy users and their neural correlates during a face-learning task
(Elsevier, 2009)It has been consistently shown that ecstasy users display impairments in learning and memory performance. In addition, working memory processing in ecstasy users has been shown to be associated with neural alterations in ... -
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 ... -
The Subiculum: What It Does, What It Might Do, And What Neuroanatomy Has Yet To Tell Us
(Anatomical Society of Great Britain and Ireland, 2005)The subiculum is a pivotal but under-investigated structure positioned between the hippocampus proper and entorhinal and other cortices, as well as a range of subcortical structures. The subiculum has a range of ... -
Variance in neurocognitive performance is associated with dysbindin-1 in schizophrenia: A preliminary study
(Elsevier, 2007)Susceptibility genes for schizophrenia have been hypothesised to mediate liability for the disorder at least partly by influencing cognitive performance. We investigated the association between genotype and cognitive ... -
Visual sensory processing deficits in Schizophrenia and their relationship to disease state
(Springer, 2008)Context: Visual Evoked Potential (VEP) abnormalities have been a fairly consistent finding in patients with schizophrenia, and it has been suggested that electrophysiological markers of early sensory processing may be ...
