Dopamine effects on frontal cortical blood flow and motor inhibition in Parkinson's disease.

Cortex 2019 Jan 29;115:99-111. Epub 2019 Jan 29.

Neurology, Vanderbilt University Medical Center, Nashville, TN, USA. Electronic address:

Parkinson's disease (PD) is characterized by dysfunction in frontal cortical and striatal networks that regulate action control. We investigated the pharmacological effect of dopamine agonist replacement therapy on frontal cortical activity and motor inhibition. Using Arterial Spin Labeling MRI, we examined 26 PD patients in the off- and on-dopamine agonist medication states to assess the effect of dopamine agonists on frontal cortical regional cerebral blood flow.

Contributions of left frontal and temporal cortex to sentence comprehension: Evidence from simultaneous TMS-EEG.

Cortex 2019 Jan 28;115:86-98. Epub 2019 Jan 28.

Research Group "Modulation of Language Networks", Department of Neuropsychology, Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany. Electronic address:

Sentence comprehension requires the rapid analysis of semantic and syntactic information. These processes are supported by a left hemispheric dominant fronto-temporal network, including left posterior inferior frontal gyrus (pIFG) and posterior superior temporal gyrus/sulcus (pSTG/STS). Previous electroencephalography (EEG) studies have associated semantic expectancy within a sentence with a modulation of the N400 and syntactic gender violations with increases in the LAN and P600.

"Looks familiar, but I do not know who she is": The role of the anterior right temporal lobe in famous face recognition.

Cortex 2019 Jan 23;115:72-85. Epub 2019 Jan 23.

Department of Neurology, Memory and Aging Center, University of California, San Francisco, CA, USA; Department of Neurology, Dyslexia Center, University of California, San Francisco, CA, USA.

Processing a famous face involves a cascade of steps including detecting the presence of a face, recognizing it as familiar, accessing semantic/biographical information about the person, and finally, if required, production of the proper name. Decades of neuropsychological and neuroimaging studies have identified a network of occipital and temporal brain regions ostensibly comprising the 'core' system for face processing. Recent research has also begun to elucidate upon an 'extended' network, including anterior temporal and frontal regions. Read More

Remodelling the attentional system after left hemispheric stroke: Effect of leftward prismatic adaptation.

Cortex 2019 Jan 24;115:43-55. Epub 2019 Jan 24.

Neuropsychology and Neurorehabilitation Service, Centre Hospitalier Universitaire Vaudois (CHUV), University of Lausanne, Lausanne, Switzerland.

Left hemispheric stroke is known to be associated with right neglect and/or not lateralized attentional deficits. The former appears to respond favourably to leftward prismatic adaptation (L-PA), as reported in a case of a large left stroke. In normal subjects, brief exposure to L-PA was shown to enhance the representation of the right visual field within the right inferior parietal lobule, emphasizing thus right hemispheric dominance within the ventral attentional system.

Abnormal fronto-striatal intrinsic connectivity reflects executive dysfunction in alcohol use disorders.

Cortex 2019 Jan 23;115:27-42. Epub 2019 Jan 23.

Scuola universitaria superiore IUSS, Pavia, Italy; Cognitive Neuroscience Laboratory, ICS Maugeri, Pavia, Italy. Electronic address:

The neural bases of cognitive impairment(s) in alcohol use disorders (AUDs) have been explained either with the specific involvement of frontal regions mostly affected by alcohol neurotoxic effects, or with a global brain damage underlying different neuro-cognitive alterations. Novel insights into this issue might come from the analysis of resting-state brain activity, representing a baseline level of intrinsic connectivity within and between the networks underlying cognitive performance. We thus addressed the neural bases of cognitive impairment(s) in 22 AUD patients, compared with 18 healthy controls, by coupling resting-state fMRI with an in-depth neuropsychological assessment of the main cognitive domains.

Electronic address:

Handedness, one of the most prominent expressions of laterality, has been historically considered unique to human. This noteworthy feature relates to contralateral inter-hemispheric asymmetries in the motor hand area following the mid-portion of the central sulcus. However, within an evolutionary approach, it remains debatable whether hand preferences in nonhuman primates are associated with similar patterns of hemispheric specialization. Read More

Left hemispatial neglect and overt orienting in naturalistic conditions: Role of high-level and stimulus-driven signals.

Cortex 2019 Jan 14;113:329-346. Epub 2019 Jan 14.

Neuroimaging Laboratory, Santa Lucia Foundation, Rome, Italy; ImpAct Team, Lyon Neuroscience Research Center, Lyon, France.

Deficits of visuospatial orienting in brain-damaged patients affected by hemispatial neglect have been extensively investigated. Nonetheless, spontaneous spatial orienting in naturalistic conditions is still poorly understood. Here, we investigated the role played by top-down and stimulus-driven signals in overt spatial orienting of neglect patients during free-viewing of short videos portraying everyday life situations.

Ventromedial frontal lobe damage affects interpretation, not exploration, of emotional facial expressions.

Cortex 2019 Jan 14;113:312-328. Epub 2019 Jan 14.

Department of Neurology and Neurosurgery, Montreal Neurological Institute, McGill University, Montreal, QC, Canada.

Recognizing and distinguishing the emotional states of those around us is crucial for adaptive social behavior. Previous work has shown that damage to the ventromedial frontal lobe (VMF) impairs recognition of subtle emotional facial expressions and affects fixation patterns to face stimuli. However, whether this relates to deficits in acquiring or interpreting facial expression information remains unclear. Read More

MRC Cognition & Brain Sciences Unit, University of Cambridge, Cambridge, UK. Electronic address:

Resting-state networks (RSNs; groups of regions consistently co-activated without an explicit task) are hugely influential in modern brain research. Despite this popularity, the link between specific RSNs and their functions remains elusive, limiting the impact on cognitive neuroscience (where the goal is to link cognition to neural systems). Here we present a series of logical steps to formally test the relationship between a coherent RSN with a cognitive domain. Read More

Intentional inhibition but not source memory is related to hallucination-proneness and intrusive thoughts in a university sample.

Cortex 2019 Jan 14;113:267-278. Epub 2019 Jan 14.

Department of Psychology, Durham University, Durham, UK.

Proneness to unusual perceptual states - such as auditory or visual hallucinations - has been proposed to exist on a continuum in the general population, but whether there is a cognitive basis for such a continuum remains unclear. Intentional cognitive inhibition (the ability to wilfully control thoughts and memories) is one mechanism that has been linked to auditory hallucination susceptibility, but most evidence to date has been drawn from clinical samples only. Moreover, such a link has yet to be demonstrated over and above relations to other cognitive skills (source monitoring) and cognitive states (intrusive thoughts) that often correlate with both inhibition and hallucinations.

Strategy-dependent modulation of cortical pain circuits for the attenuation of pain.

Cortex 2019 Jan 4;113:255-266. Epub 2019 Jan 4.

Wellcome Centre for Integrative Neuroimaging, FMRIB, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, UK.

The effectiveness of cognitive strategies to attenuate pain has been reported in various behavioural studies, however the underlying neuronal mechanisms are only now beginning to be understood. Using a 7 T fMRI, we investigated three different pain attenuation strategies in 20 healthy subjects via: (a) non-imaginal distraction by counting backwards in steps of seven; (b) imaginal distraction by imagining a safe place; and (c) reinterpretation of the pain valence (reappraisal). Although we found considerable variability in the performances, all strategies exhibited a significant relief of pain compared to an unmodulated pain condition. Read More

Anatomo-functional characterisation of the human "hand-knob": A direct electrophysiological study.

Cortex 2018 Dec 24;113:239-254. Epub 2018 Dec 24.

Laboratory of Motor Control, Department of Medical Biotechnologies and Translational Medicine, Università Degli Studi di Milano, Humanitas Research Hospital, IRCCS, Milano, Italy. Electronic address:

The cortical area within the human primary motor cortex (M1) that hosts the representation of the hand and fingers is known as the 'hand-knob' and is essential for voluntary hand movement. The anatomo-functional heterogeneity described within the monkey primary motor cortex (M1) in a rostro-caudal direction suggests an internal subdivision in two sectors originating different systems of connections to the spinal cord. Direct investigation of the human hand-knob has been prevented, so far, by methodological constraints. Read More

Evidence for the world as an external memory: A trade-off between internal and external visual memory storage.

Cortex 2019 Jan 3. Epub 2019 Jan 3.

Experimental Psychology, Helmholtz Institute, Utrecht University, Utrecht, the Netherlands.

We use visual working memory (VWM) to maintain the visual features of objects in our world. Although the capacity of VWM is limited, it is unlikely that this limit will pose a problem in daily life, as visual information can be supplemented with input from our external visual world by using eye movements. In the current study, we influenced the trade-off between eye movements and VWM utilization by introducing a cost to a saccade. Read More

Spontaneous representation of numerosity in typical and dyscalculic development.

Cortex 2018 Dec 28. Epub 2018 Dec 28.

Department of Neuroscience, Psychology, Pharmacology and Child Health, University of Florence, Florence, Italy; School of Psychology, University of Sydney, Sydney, Australia.

Animals including humans are endowed with a remarkable capacity to estimate rapidly the number of items in a scene. Some have questioned whether this ability reflects a genuine sense of number, or whether numerosity is derived indirectly from other covarying attributes, such as density and area. In previous work we have demonstrated that adult observers are more sensitive to changes in numerosity than to area or density, particularly changes that leave numerosity constant, pointing to a spontaneous sensitivity to numerosity, not attributable to area and density.

Department of Psychology, Queens College, The City University of New York, Flushing, NY, USA; Departments of Psychiatry, Icahn School of Medicine at Mount Sinai, New York, NY, USA; Departments of Neuroscience, Icahn School of Medicine at Mount Sinai, New York, NY, USA. Electronic address:

Over forty years have passed since the first evidence showing the unbalanced attentional allocation of humans across the two visual fields, and since then, a wealth of behavioral, neurophysiological, and clinical data increasingly showed a right hemisphere dominance for orienting of attention. However, inconsistent evidence exists regarding the right-hemisphere dominance for executive control of attention, possibly due to a lack of consideration of its dynamics with the alerting and orienting functions. In this study, we used a version of the Attentional Network Test with lateralized presentation of the stimuli to the left visual field (processed by the right hemisphere, RH) and right visual field (processed by the left hemisphere, LH) to examine visual field differences in executive control of attention under alerting and orienting of attention.

Visual short-term memory (VSTM) is an important cognitive capacity that varies across the healthy adult population and is affected in several neurodevelopmental disorders. It has been suggested that neuroanatomy places limits on this capacity through a map architecture that creates competition for cortical space. This suggestion has been supported by the finding that primary visual (V1) gray matter volume (GMV) is positively associated with VSTM capacity. Read More

Dopamine guides competition for cognitive control: Common effects of haloperidol on working memory and response conflict.

Department of Experimental Psychology, University of Oxford, Oxford, UK; Nuffield Department of Clinical Neurosciences, John Radcliffe Hospital, Oxford, UK.

Several lines of evidence suggest that dopamine modulates working memory (the ability to faithfully maintain and efficiently manipulate information over time) but its specific role has not been fully defined. Nor is it clear whether any effects of dopamine are specific to memory processes or whether they reflect more general cognitive mechanisms that extend beyond the working memory domain. Here, we examine the effect of haloperidol, principally a dopamine D receptor antagonist, on the ability of humans to ignore distracting information or update working memory contents. Read More

The impact of spelling regularity on handwriting production: A coupled fMRI and kinematics study.

Cortex 2018 Dec 10;113:111-127. Epub 2018 Dec 10.

Laboratoire de Neurosciences Cognitives, UMR 7291, CNRS - Aix-Marseille University, Marseille, France.

Current models of writing assume that the orthographic processes involved in spelling retrieval and the motor processes involved in the control of the hand are independent. This view has been challenged by behavioral studies, which showed that the linguistic features of words impact motor execution during handwriting. We designed an experiment coupling functional magnetic resonance imaging and kinematic recordings during a writing to dictation task. Read More

A sensorimotor view of verbal working memory.

Cortex 2018 Nov 20. Epub 2018 Nov 20.

Helen Wills Neuroscience Institute, Department of Psychology, University of California, Berkeley, USA.

The divide-and-conquer approach to the study of human cognition has succeeded in focusing researchers' efforts on behavioral phenomena that fall under well-defined categories such as attention, perception, language, memory, emotion, and motor control. The result has been the development of coherent bodies of work in each area replete with successful explanatory theories and a rich collection of paradigms, tasks, and analytic techniques. There has been a renewed in recent years in combining and integrating ideas across these domains, as well as in incorporating neuroscientific data, as a way to build more powerful and general models of cognition.

Voluntary modulation of saccadic peak velocity associated with individual differences in motivation.

Cortex 2018 Dec 14. Epub 2018 Dec 14.

Nuffield Department of Clinical Neurosciences, University of Oxford, UK; Department of Experimental Psychology, University of Oxford, UK.

Saccadic peak velocity increases in a stereotyped manner with the amplitude of eye movements. This relationship, known as the main sequence, has classically been considered to be fixed, although several recent studies have demonstrated that velocity can be modulated to some extent by external incentives. However, the ability to voluntarily control saccadic velocity and its association with motivation has yet to be investigated. Read More

Increased inhibition following negative cues: A possible role for enhanced processing.

Cortex 2018 Dec 21. Epub 2018 Dec 21.

Department of Psychology, University of Haifa, Israel; The Institute of Information Processing and Decision Making (IIPDM), University of Haifa, Israel. Electronic address:

Based on findings showing that attention is captured by aversive stimuli, previous studies have hypothesized that inhibition of return (IOR) is reduced at spatial locations previously occupied by threat cues. Yet evidence for this view is limited: Only a few studies have demonstrated a reduced degree of IOR following threat cues, while most have not found differences in IOR between aversive and neutral cues. In contrast to previous studies that used the spatial cuing paradigm and for the most part employed mild negative stimuli as cues, we examined the influence of highly aversive, colored and complex pictures of real life situations.

Neural correlates of effort-based behavioral inconsistency.

Cortex 2018 Dec 15;113:96-110. Epub 2018 Dec 15.

University of Navarra, Institute for Culture and Society (ICS), Mind-Brain Group, Pamplona, Spain; University of Navarra, Center for Applied Medical Research (CIMA), Neuroimaging Laboratory, Pamplona, Spain.

According to the theory of value-based decision making, subjects tend to choose the most valuable among a set of options. However, agents may not be consistent when facing the same decision several times. In this paper, Shannon's entropy (H) is employed as a measure of behavioral inconsistency: it is a central measure of information theory that, applied to decision making, allows the estimation of behavioral preferences among a set of options.

Developmental specialization of the left intraparietal sulcus for symbolic ordinal processing.

Cortex 2018 Dec 8. Epub 2018 Dec 8.

Numerical Cognition Laboratory, Department of Psychology and Brain & Mind Institute, Western University, London ON, Canada. Electronic address:

Symbolic numbers have both cardinal (symbol-quantity) and ordinal (symbol-symbol) referents. Despite behavioural evidence suggesting distinct processing of cardinal and ordinal referents, little consensus has emerged from the neuroimaging literature on whether these processes have shared or distinct neural underpinnings. Moreover, it remains unclear how the neural correlates of cardinal and ordinal processing change with age. Read More

Anatomical predictors of successful prism adaptation in chronic visual neglect.

Cortex 2018 Dec 15. Epub 2018 Dec 15.

Visual neglect is a frequent and disabling consequence of right hemisphere damage. Previous work demonstrated a probable role of posterior callosal dysfunction in the chronic persistence of neglect signs. Prism adaptation is a non-invasive and convenient technique to rehabilitate chronic visual neglect, but it is not effective in all patients. Read More

Visual search pattern during free viewing of horizontally flipped images in patients with unilateral spatial neglect.

Cortex 2018 Dec 14;113:83-95. Epub 2018 Dec 14.

Department of Rehabilitation for the Movement Functions, Research Institute, National Rehabilitation Center for Persons with Disabilities, Saitama, Japan; Neurorehabilitation Research Center, Kio University, Nara, Japan. Electronic address:

Eye tracking is an effective tool for identifying behavioural aspects of unilateral spatial neglect (USN), which is a common neurological syndrome that develops after a right hemisphere lesion. Here, we attempted to elucidate how the neglect symptom affects the symmetry of the gaze pattern, by performing an analysis of gaze distribution during the free viewing of a pair of horizontally flipped images. Based on their Behavioural Inattention Test (BIT) scores, 41 patients with right-hemisphere damage were classified into those with USN (n = 27) and those without USN (right hemisphere damaged - RHD; n = 14).

Sensory-motor integration and brain lesions: Progress toward explaining domain-specific phenomena within domain-general working memory.

Cortex 2018 Dec 15. Epub 2018 Dec 15.

University of Missouri, USA.

Reports of rare patients who seem to lack the ability to retain certain types of information across brief delays have long sustained the popular idea that newly-perceived verbal, visual, and spatial information is initially recorded in separate, specialized short-term memory buffers. However, evidence from these same cases includes puzzling details that question explanations based on isolated deficits to a specialized storage system. We highlight consistent findings from patients with deficient auditory short-term memory that warrant further investigation and may challenge the specialized store account, including that short-term recognition memory performance appears to be much stronger than recall, and not so obviously impaired.

Effects of morphological family on word recognition in normal aging, mild cognitive impairment, and Alzheimer's disease.

Cortex 2018 Dec 11. Epub 2018 Dec 11.

University of Eastern Finland, Kuopio, Finland; Kuopio University Hospital, Kuopio, Finland. Electronic address:

Reading a word activates morphologically related words in the mental lexicon. People with Alzheimer's disease (AD) or Mild Cognitive Impairment (MCI) often have difficulty retrieving words, though the source of this problem is not well understood. To better understand the word recognition process in aging and in neurodegenerative disorders such as MCI and AD, we investigated the nature of the activation of morphologically related family members in 22 Finnish speakers with AD, 24 with MCI, and 17 cognitively healthy elderly.
