Access to health care of persons with disabilities as an indicator of equity in health systems
(2011)The outcomes of certain health services can be used to assess the overall effectiveness of a health care system. For example, maternal mortality is an indicator of the quality of a country?s maternal health services, which ... -
Activation and deactivation during the rapid visual information processing task: an fMRI study.
(MIT Press, 2003)Sustained attention deficits occur in several neuropsychi- atric disorders. However, the underlying neurobiological mechanisms are still incompletely understood. To that end, functional MRI was used to investigate ... -
Acute effects of cocaine on the neurobiology of cognitive control
(Royal Society Publishing, 2008)Compromised ability to exert control over drug urges and drug-seeking behaviour is a characteristic of addiction. One specific cognitive control function, impulse control, has been shown to be a risk factor for the development ... -
Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males
(2011)Physical activity has been reported to improve cognitive function in humans and rodents, possibly via a brain-derived neurotrophic factor (BDNF)-regulated mechanism. In this study of human subjects, we have assessed the ... -
Anorexia, bulimia, and obesity: Shared decision making deficits on the Iowa Gambling Task (IGT).
(Cambridge University Press, 2010)The pathological eating behaviors in Anorexia Nervosa (AN), Bulimia Nervosa (BN), and obesity are characterized by a preference for high immediate reward, despite higher future losses in terms of both physical and psychological ... -
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 ... -
The anterior thalamus provides a subcortical circuit supporting memory and spatial navigation.
(2013)The anterior thalamic nuclei (ATN), a central component of Papez' circuit, are generally assumed to be key constituents of the neural circuits responsible for certain categories of learning and memory. Supporting evidence ... -
Anticipatory planning reveals segmentation of cortical motor output during action observation
(2015)It has been argued that the variation in brain activity that occurs when observing another person reflects a representation of actions that is indivisible, and which plays out in full once the intent of the actor can be ... -
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 ... -
Artificial Gravity Reveals that Economy of Action Determines the Stability of Sensorimotor Coordination
(2009)Abstract Background: When we move along in time with a piece of music, we synchronise the downward phase of our gesture with the beat. While it is easy to demonstrate this tendency, there is considerable debate as to ... -
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 ... -
Atrial fibrillation and cognitive function: a case control study
(2005)Atrial fibrillation is an important and independent risk factor for cerebrovascular disease and vascular dementia. There is increasing evidence that atrial fibrillation is associated with an increased risk of asymptomatic ... -
Attentional load asymmetrically affects early electrophysiological indices of visual orienting.
(2011)Recent behavioral studies suggest that asymmetries in visuospatial orienting are modulated by changes in the demand on nonspatial components of attention, but the brain correlates of this modulation are unknown. We used ... -
Automated spike sorting algorithm based on Laplacian eigenmaps and k-means clustering
(2011)This study presents a new automatic spike sorting method based on feature extraction by Laplacian eigenmaps combined with k-means clustering. The performance of the proposed method was compared against previously reported ... -
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 ... -
Aversive learning in adolescents: modulation by amygdala-prefrontal and amygdala-hippocampal connectivity and neuroticism.
(2014)Neuroticism involves a tendency for enhanced emotional and cognitive processing of negative affective stimuli and a propensity to worry and be anxious. It is known that this trait modulates fear learning and the activation ...
