Neuromotor and Cognitive Rehabilitation Research Center, Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, 37134 Verona, Italy.

Hemispatial neglect is a common consequence of stroke, with an estimated incidence of 23%. Interventions for treating hemispatial neglect may be categorized as either top-down or bottom-up processing. The aim of top-down approaches is to train the person to voluntarily compensate for their neglect. Read More

Development of the Halifax Visual Scanning Test: A New Measure of Visual-Spatial Neglect for Personal, Peripersonal, and Extrapersonal Space.

J Int Neuropsychol Soc 2019 Apr 16:1-11. Epub 2019 Apr 16.

1Department of Psychology and Neuroscience,Dalhousie University,Nova Scotia.

Objectives: Visual-spatial neglect is a common attentional disorder after right-hemisphere stroke and is associated with poor rehabilitation outcomes. The presence of neglect symptoms has been reported to vary across personal, peripersonal, and extrapersonal space. Currently, no measure is available to assess neglect severity equally across these spatial regions and may be missing subsets of symptoms or patients with neglect entirely. Read More

Case of right hemispatial neglect and transcortical sensory aphasia following left occipitotemporoparietal glioblastoma resection.

Appl Neuropsychol Adult 2019 Apr 15:1-7. Epub 2019 Apr 15.

a Department of Psychiatry , University of Illinois College of Medicine , Chicago , Illinois , USA.

The neurobehavioral syndrome of hemispatial neglect, which can result from insults such as stroke, brain tumor, or head injury, has most frequently been described as occurring for the left-side of hemispace following lesions to the right hemisphere. While right hemispatial neglect/inattention may occur following left hemisphere lesions as well, it has received limited attention in the scientific literature. The present case describes an inpatient neuropsychological evaluation with a 67-year-old, African American man presenting with right hemispatial neglect following resection of a large glioblastoma in the left occipitotemporoparietal region.

Systems Ecology, Free University, De Boelelaan 1087, Amsterdam, 1081 HV, Netherlands.

Neutral models are often used as null models, testing the relative importance of niche versus neutral processes in shaping diversity. Most versions, however, focus only on regional scale predictions and neglect local level contributions. Recently, a new formulation of spatial neutral theory was published showing an incompatibility between regional and local scale fits where especially the number of rare species was dramatically under-predicted.

Perturbation-driven paradoxical facilitation of visuo-spatial function: Revisiting the 'Sprague effect'.

Cortex 2019 Feb 10. Epub 2019 Feb 10.

Laboratory for Cerebral Dynamics, Plasticity & Rehabilitation, Boston University School of Medicine, Boston, MA, USA. Electronic address:

The 'Sprague Effect' described in the seminal paper of James Sprague (Science 153:1544-1547, 1966a) is an unexpected paradoxical effect in which a second brain lesion reversed functional deficits induced by an earlier lesion. It was observed initially in the cat where severe and permanent contralateral visually guided attentional deficits generated by the ablation of large areas of the visual cortex were reversed by the subsequent removal of the superior colliculus (SC) opposite to the cortical lesion or by the splitting of the collicular commissure. Physiologically, this effect has been explained in several ways-most notably by the reduction of the functional inhibition of the ipsilateral SC by the contralateral SC, and the restoration of normal interactions between cortical and midbrain structures after ablation.

The hemispheric distribution of α-band EEG activity during orienting of attention in patients with reduced awareness of the left side of space (spatial neglect).

J Neurosci 2019 Mar 22. Epub 2019 Mar 22.

Fondazione Santa Lucia, Centro Ricerche di Neuropsicologia, IRCCS, Via Ardeatina 306, 00179 Roma, Italy

EEG studies in healthy humans have highlighted that alpha-band activity is relatively reduced over the occipital-parietal areas of the hemisphere contralateral to the direction of spatial attention. Here, we investigated the hemispheric distribution of alpha during orienting of attention in male and female right-brain-damaged patients with left spatial neglect. Temporal spectral evolution showed that in patients with neglect alpha oscillations over the damaged hemisphere were pathologically enhanced both during the baseline-fixation period that preceded cued orienting (capturing tonic alpha changes) and during orienting with leftward, rightward or neutral-bilateral spatial cues (reflecting phasic alpha changes).

Plasmonic metaresonances: harnessing nonlocal effects for prospective biomedical applications.

J Phys Condens Matter 2019 Mar 21. Epub 2019 Mar 21.

Advanced Computing and Simulation Laboratory, Monash University, Clayton,, Victoria 3800, Melbourne, Victoria, 3800, AUSTRALIA.

Metal nanoparticles (MNPs) possess optical concentration capabilities that can amplify and localize electromagnetic fields into nanometer length scales. The near-fields of MNPs can be used to tailor optical response of luminescent semiconductor quantum dots (QDs), resulting in fascinating optical phenomena. Plasmonic metaresonances (PMRs) form a class of such optical events gaining increasing popularity due to their promising prospects in sensing and switching applications. Read More

Functional Neuroanatomy of Vertical Visual Perception in Humans.

Front Neurol 2019 25;10:142. Epub 2019 Feb 25.

SCALab, CNRS, Lille University, Lille, France.

Vertical representation is central to posture control, as well as to spatial perception and navigation. This representation has been studied for a long time in patients with vestibular disorders and more recently in patients with hemispheric damage, in particular in those with right lesions causing spatial or postural deficits. The aim of the study was to determine the brain areas involved in the visual perception of the vertical. Read More

Implicit representation of the auditory space: contribution of the left and right hemispheres.

Brain Struct Funct 2019 Mar 8. Epub 2019 Mar 8.

Service de neuropsychologie et de neuroréhabilitation, Centre Hospitalier Universitaire Vaudois (CHUV), Université de Lausanne, Lausanne, Switzerland.

Spatial cues contribute to the ability to segregate sound sources and thus facilitate their detection and recognition. This implicit use of spatial cues can be preserved in cases of cortical spatial deafness, suggesting that partially distinct neural networks underlie the explicit sound localization and the implicit use of spatial cues. We addressed this issue by assessing 40 patients, 20 patients with left and 20 patients with right hemispheric damage, for their ability to use auditory spatial cues implicitly in a paradigm of spatial release from masking (SRM) and explicitly in sound localization.

Evidence for a common mechanism of spatial attention and visual awareness: Towards construct validity of pseudoneglect.

PLoS One 2019 7;14(3):e0212998. Epub 2019 Mar 7.

Department of Psychology, University of Toronto, Toronto, Ontario, Canada.

Present knowledge of attention and awareness centres on deficits in patients with right brain damage who show severe forms of inattention to the left, called spatial neglect. Yet the functions that are lost in neglect are poorly understood. In healthy people, they might produce "pseudoneglect"-subtle biases to the left found in various tests that could complement the leftward deficits in neglect. Read More

Wearing prisms to hear differently: After-effects of prism adaptation on auditory perception.

Cortex 2019 Feb 7;115:123-132. Epub 2019 Feb 7.

LEAD, CNRS UMR5022, Université Bourgogne Franche-Comté, Dijon, France.

Numerous studies showed that, after adaptation to a leftward optical deviation, pseudoneglect behavior (overrepresentation of the left part compared to the right part of the space) becomes neglect-like behavior (overrepresentation of the right part compared to the left part of the space). Cognitive after-effects have also been shown in cognitive processes that are not intrinsically spatial in nature, but show spatial association as numbers or letters. The space-auditory frequency association (with low frequencies on the left and high frequencies on the right) raises the question of whether prism adaptation can produce after-effects on auditory perception.

Is Unilateral Spatial Neglect Associated With Motor Recovery of the Affected Upper Extremity Poststroke? A Systematic Review.

Neurorehabil Neural Repair 2019 Mar 20;33(3):179-187. Epub 2019 Feb 20.

2 School of Health Professions, Sackler Faculty of Medicine, Tel Aviv University, Israel.

Background And Purpose: Individuals with stroke often present symptoms of multiple domains, such as weakness of the affected upper extremity (UE) and unilateral spatial neglect (USN), which are both associated with poor functional outcome. The aims of this systematic review were to search and review studies that investigated (1) the relationship between USN and affected UE sensorimotor recovery poststroke and (2) the effectiveness of sensorimotor interventions to improve the affected UE in patients with USN.

Methods: An electronic search of databases (MEDLINE, EMBASE, CINAHL and Cochrane CENTRAL) was conducted using a combination of the following terms: stroke, USN, and affected UE. Read More

Theta burst stimulation in neglect after stroke: functional outcome and response variability origins.

Brain 2019 Apr;142(4):992-1008

Gerontechnology and Rehabilitation Group, ARTORG Center for Biomedical Engineering Research, University of Bern, Switzerland.

Spatial neglect is a strong and negative predictor of general functional outcome after stroke, and its therapy remains a challenge. Whereas inhibitory non-invasive brain stimulation over the contralesional, intact hemisphere has generally been shown to ameliorate neglect on a group level, a conspicuous variability of the effects at the individual level is typically observed. We aimed to assess the characteristics and determinants of the effects of inhibitory non-invasive brain stimulation in neglect, identifying which patients would respond to this therapeutic approach and which not.

Spatial Attention Deficits Are Causally Linked to an Area in Macaque Temporal Cortex.

Curr Biol 2019 Mar 14;29(5):726-736.e4. Epub 2019 Feb 14.

Laboratory of Sensorimotor Research, National Eye Institute, NIH, Bethesda, MD 20892, USA. Electronic address:

Spatial neglect is a common clinical syndrome involving disruption of the brain's attention-related circuitry, including the dorsocaudal temporal cortex. In macaques, the attention deficits associated with neglect can be readily modeled, but the absence of evidence for temporal cortex involvement has suggested a fundamental difference from humans. To map the neurological expression of neglect-like attention deficits in macaques, we measured attention-related fMRI activity across the cerebral cortex during experimental induction of neglect through reversible inactivation of the superior colliculus and frontal eye fields.

Department of Psychology, Rome University "La Sapienza", Rome, Italy.

The SNARC effect reflects the observation that when healthy observers with left-to-right reading habits are asked to compare the magnitude or to judge the parity of numbers, they provide faster reaction times (RT) to small numbers with left-sided responses and faster RTs to large numbers with right-sided responses. In magnitude comparison (MC), right brain damaged patients with left-sided neglect typically show a pathologically enlarged SNARC for large numbers and selective slowing to numbers that are immediately lower than the numerical reference (e.g. Read More

Hemispheric lateralization of attention processes in the human brain.

Curr Opin Psychol 2019 Jan 4;29:90-96. Epub 2019 Jan 4.

Inserm U 1127, CNRS UMR 7225, Sorbonne Université, Institut du Cerveau et de la Moelle épinière, ICM, Hôpital de la Pitié-Salpêtrière, 75013 Paris, France.

We review recent evidence for the hemispheric lateralization of attentional systems in the human brain. There is abundant anatomical, neuroimaging, and neuromodulatory evidence for a relative lateralization toward the right hemisphere of some of the cortical networks supporting the attentional systems, especially those including the temporo-parietal junction and the ventro-lateral prefrontal cortex. Damage or disconnection of these right-lateralized nodes may produce severe deficits of spatial and nonspatial attention, as in visual neglect, or of inhibitory control. Read More

No direction specific costs in trans-saccadic memory.

Neuropsychologia 2019 Mar 26;125:23-29. Epub 2019 Jan 26.

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

Even though we frequently execute saccades, we perceive the external world as coherent and stable. An important mechanism of trans-saccadic perception is spatial remapping: the process of updating information across eye movements. Previous studies have indicated a right hemispheric dominance for spatial remapping, which has been proposed to translate into enhanced trans-saccadic memory for locations that are remapped into the right compared to the left hemisphere in healthy participants.

Long-term effects of institutional rearing, foster care, and brain activity on memory and executive functioning.

Proc Natl Acad Sci U S A 2019 01 14;116(5):1808-1813. Epub 2019 Jan 14.

Laboratories of Cognitive Neuroscience, Boston Children's Hospital and Harvard Medical School, Boston, MA 02215.

Children experiencing psychosocial deprivation as a result of early institutional rearing demonstrate many difficulties with memory and executive functioning (EF). To date, there is scant evidence that foster care placement remediates these difficulties during childhood. The current study examined longitudinal trajectories of memory and EF from childhood to adolescence in the Bucharest Early Intervention Project, a randomized controlled trial of foster care for institutionally reared children.

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

Cortex 2019 Apr 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).

Judgement bias testing in group-housed gestating sows.

Behav Processes 2019 Feb 2;159:86-92. Epub 2019 Jan 2.

Department of Clinical Studies, University of Pennsylvania School of Veterinary Medicine, 382 W Street Road, Kennett Square, PA, 19348, USA.

Societal concerns about animal welfare have triggered the movement of gestating sows from individual stalls to group housing in many countries. Common methods of assessing sow welfare focus on overt physical ailments, and potentially neglect psychological stressors. A judgement bias task may allow researchers to evaluate an animal's subjective mental or affective state to provide a more comprehensive welfare assessment. Read More

Contribution of transcranial magnetic stimulation in assessing parietofrontal connectivity during gesture production in healthy individuals and brain-injured patients.

Neurophysiol Clin 2019 Apr 29;49(2):115-123. Epub 2018 Dec 29.

Inserm U1171, University Lille, Degenerative and Vascular Cognitive Disorders, 59000 Lille, France; Department of Clinical Neurophysiology, Lille University Medical Center, 59000 Lille, France.

Parietofrontal (PF) networks link the posterior parietal cortex to premotor and prefrontal areas, and are involved in the control of many motor and cognitive behaviors in healthy humans. In recent years, electrophysiological experiments have provided a better understanding of the functional specificity and temporal involvement of the PF networks' different components during the planning of visually guided upper limb movements. In particular, transcranial magnetic stimulation has been used to temporarily inactivate a cortical area (virtual lesions) or to assess connectivity using paired-pulse protocols)). Read More

The elephant in the room? Why spatial stigma does not receive the public health attention it deserves.

J Public Health (Oxf) 2018 Dec 20. Epub 2018 Dec 20.

Division of Health Research, Faculty of Health and Medicine, Lancaster University, Lancaster, UK.

In the context of health inequalities, spatial stigma refers to the ways that areas experiencing socioeconomic inequalities become negatively portrayed and labelled in public, official and policy discourses. With respect to the body of research on social determinants of health and health inequalities, and attention accorded to this issue in policy or practice, spatial stigma remains significantly under-represented compared with other possible causal factors. We suggest three explanations contributing to this neglect. Read More

Re-fixation and perseveration patterns in neglect patients during free visual exploration.

Eur J Neurosci 2018 Dec 17. Epub 2018 Dec 17.

Gerontechnology & Rehabilitation Group, University of Bern, Bern, Switzerland.

The literature suggests that neglect patients not only show impairments in directing attention toward the left, contralesional space, but also present with perseverative behavior. Moreover, previous studies described re-fixations during visual search tasks, and interpreted this finding as an impairment of spatial working memory. The aim of the present study was to study re-fixations and perseverations (i. Read More

Unilateral neglect post stroke: Eye movement frequencies indicate directional hypokinesia while fixation distributions suggest compensational mechanism.

Brain Behav 2019 Jan 12;9(1):e01170. Epub 2018 Dec 12.

Department of Psychology, University of Oslo, Oslo, Norway.

Introduction: Eye movements and spatial attention are closely related, and eye-tracking can provide valuable information in research on visual attention. We investigated the pathology of overt attention in right hemisphere (RH) stroke patients differing in their severity of neglect symptoms by using eye-tracking during a dynamic attention task.

Methods: Eye movements were recorded in 26 RH stroke patients (13 with and 13 without unilateral spatial neglect, and a matched group of 26 healthy controls during a Multiple Object Tracking task. Read More

Ventral attention and motor network connectivity is relevant to functional impairment in spatial neglect after right brain stroke.

Brain Cogn 2019 02 3;129:16-24. Epub 2018 Dec 3.

Kessler Foundation, 1199 Pleasant Valley Way, West Orange, NJ 07052, USA; Rutgers New Jersey Medical School, Newark, NJ 07102, USA. Electronic address:

Emerging research suggests spatial neglect after right stroke is linked to dysfunctional attention and motor networks. Advanced functional connectivity analysis clarified brain network recovery, however we need to know how networks participate in adaptive motor performance. We need to verify network changes associated with validated functional measures and spatial-motor performance in spatial neglect, especially in patients with large brain lesions and significant disability.

Meta-analysis of the visuospatial aftereffects of prism adaptation, with two novel experiments.

Cortex 2019 Feb 19;111:256-273. Epub 2018 Nov 19.

Clinical Neuropsychology, Department of Clinical Neurosciences, Western General Hospital, NHS Lothian, Edinburgh, UK.

We present a meta-analysis of the effects of visuomotor adaptation to leftward displacing prisms on visuospatial judgements in healthy people, as assessed by perceptual (landmark) and manual versions of the line bisection task. To supplement previously published datasets, we report two novel experiments: Experiment 1 (n = 12) found null effects of adaptation to 10° leftward prisms on spatial bias in the landmark task, and Experiment 2 (n = 24) found null effects of 12° leftward prisms on spatial bias in a computerised line bisection task. Including these data, we considered 17 experiments for the landmark task (total n = 256), and 12 experiments for line bisection (total n = 172), in which participants were adapted for between 7 and 20 min to prism strengths from 8 to 17°.
