Subliminal galvanic-vestibular stimulation recalibrates the distorted visual and tactile subjective vertical in right-sided stroke
In conclusion, we found that GVS rapidly influences poststroke verticality deficits in the visual and tactile modality, thus highlighting the importance of the vestibular system in the multimodal elaboration of the subjective vertical.

A predictive model for diagnosing stroke-related apraxia of speech
Publication date: Available online 19 December 2015 Source:Neuropsychologia Author(s): Kirrie J. Ballard, Lamiae Azizi, Joseph R. Duffy, Malcolm R. McNeil, Mark Halaki, Nicholas O’Dwyer, Claire Layfield, Dominique I. Scholl, Adam P. Vogel, Donald A. Robin Diagnosis of the speech motor planning/programming disorder, apraxia of speech (AOS), has proven challenging, largely due to its common co-occurrence with the language-based impairment of aphasia. Currently, diagnosis is based on perceptually identifying and rating the severity of several speech features. It is not known whether all, or a subset of the featu...

Visual Attention in Posterior Stroke and Relations to Alexia
In conclusion, visual span may be affected bilaterally by unilateral PCA-lesions. Reductions in visual span may also be confined to one hemifield, and may be affected in spite of preserved visual processing speed. Furthermore, reduced span in the right visual field seems to be related to reading impairment in this group, regardless of lesion lateralization.

The Effects of Motivational Reward on the Pathological Attentional Blink following Right Hemisphere Stroke
Publication date: Available online 6 April 2016 Source:Neuropsychologia Author(s): Korina Li, Charlotte Russell, Nikita Balaji, Youssuf Saleh, David Soto, Paresh A. Malhotra Recent work has shown that attentional deficits following stroke can be modulated by motivational stimulation, particularly anticipated monetary reward. Here we examined the effects of anticipated reward on the pathological attentional blink (AB), an index of temporal selective attention, which is prolonged in patients with right hemisphere damage and a history of left neglect. We specifically compared the effects of reward versus feedback-with...

Selective associative phonagnosia after right anterior temporal stroke
We report the case of a 48 year old men who developed a selective impairment in famous voice recognition after ischemic stroke in right subcortical structures (lenticular nucleus and head of the caudate) and right anterior temporal lobe. He underwent fibrinolytic treatment. During the following days he progressively recovered and was discharged without neurological focal sign. Patent foramen ovale was found. When he got back to his house he noticed that he was unable to recognize the voice of his favoured singers and needed to ask who was the singer to his relatives. Neuropsychological examination revealed a selective impa...

Does it fit? – Impaired affordance perception after stroke
Publication date: 8 January 2018 Source:Neuropsychologia, Volume 108 Author(s): Jennifer Randerath, Lisa Finkel, Cheryl Shigaki, Joe Burris, Ashish Nanda, Peter Hwang, Scott H. Frey Affordance perception comprises the evaluation of whether our given bodily capabilities and properties of the environment allow particular actions. Typical impairments after left brain damage in motor cognition as well as after right brain damage in visuo-spatial abilities may affect the evaluation of whether interactions with objects are possible. Further it is unclear whether deficient motor function is accounted for when deciding upon actio...

Neural correlates of visuospatial bias in patients with left hemisphere stroke: a causal functional contribution analysis based on game theory
Publication date: 1 July 2018Source: Neuropsychologia, Volume 115Author(s): C. Malherbe, R.M. Umarova, M. Zavaglia, C.P. Kaller, L. Beume, G. Thomalla, C. Weiller, C.C. HilgetagAbstractStroke patients frequently display spatial neglect, an inability to report, or respond to, relevant stimuli in the contralesional space. Although this syndrome is widely considered to result from the dysfunction of a large-scale attention network, the individual contributions of damaged grey and white matter regions to neglect are still being disputed. Moreover, while the neuroanatomy of neglect in right hemispheric lesions is well studied, ...

Cerebellar contribution to vocal emotion decoding: Insights from stroke and neuroimaging
Publication date: Available online 12 July 2019Source: NeuropsychologiaAuthor(s): Marine Thomasson, Arnaud Saj, Damien Benis, Didier Grandjean, Frédéric Assal, Julie PéronAbstractWhile the role of the cerebellum in emotion recognition has been explored with facial expressions, its involvement in the auditory modality (i.e., emotional prosody) remains to be demonstrated. The present study investigated the recognition of emotional prosody in 15 patients with chronic cerebellar ischaemic stroke and 15 matched healthy controls, using a validated task, as well as clinical, motor, neuropsychological, and psychiatric assessmen...

Concepts within reach: Action performance predicts action language processing in stroke
Publication date: Available online 6 April 2015 Source:Neuropsychologia Author(s): Rutvik H. Desai , Troy Herter , Nicholas Riccardi , Chris Rorden , Julius Fridriksson The relationship between the brain's conceptual or semantic and sensory-motor systems remains controversial. Here, we tested manual and conceptual abilities of 41 chronic stroke patients in order to examine their relationship. Manual abilities were assed through a reaching task using an exoskeleton robot. Semantic abilities were assessed with implicit as well as explicit semantic tasks, for both verbs and nouns. The results show that that the degree of se...

The role of the right hemisphere in semantic control: A case-series comparison of right and left hemisphere stroke
Publication date: Available online 2 March 2016 Source:Neuropsychologia Author(s): Hannah E. Thompson, Lauren Henshall, Elizabeth Jefferies Semantic control processes guide conceptual retrieval so that we are able to focus on non-dominant associations and features when these are required for the task or context, yet the neural basis of semantic control is not fully understood. Neuroimaging studies have emphasised the role of left inferior frontal gyrus (IFG) in controlled retrieval, while neuropsychological investigations of semantic control deficits have almost exclusively focussed on patients with left-sided damage ...

Multi-tasking uncovers right spatial neglect and extinction in chronic left-hemisphere stroke patients
Publication date: Available online 3 March 2016 Source:Neuropsychologia Author(s): Elvio Blini, Zaira Romeo, Chiara Spironelli, Marco Pitteri, Francesca Meneghello, Mario Bonato, Marco Zorzi Unilateral Spatial Neglect, the most dramatic manifestation of contralesional space unawareness, is a highly heterogeneous syndrome. The presence of neglect is related to core spatially lateralized deficits, but its severity is also modulated by several domain-general factors (such as alertness or sustained attention) and by task demands. We previously showed that a computer-based dual-task paradigm exploiting both lateralized...

Investigating the Extent of Neuroplasticity: Writing in Children with Perinatal Stroke
Publication date: Available online 8 June 2016 Source:Neuropsychologia Author(s): Darin Woolpert, Judy S. Reilly The developing brain is remarkably plastic, as evidenced by language studies of children with perinatal stroke (PS). Despite initial delays and in contrast to adults with comparable lesions, children with PS perform comparably to their age-matched peers in free conversation by school age. Recent studies of spoken language in older children with PS have indicated limits to neural plasticity. Writing, a cognitively demanding and language dependent domain, is understudied in children with PS. Investigating writ...

Assessing the temporal aspects of attention and its correlates in aging and chronic stroke patients
Publication date: Available online 2 August 2016 Source:Neuropsychologia Author(s): Nir Shalev, Glyn Humphreys, Nele Demeyere Temporal dynamics of attention have been in the spotlight of research since the earliest days of cognitive psychology. Typically, researchers describe two different aspects of the temporal fluctuations of attention: one is in intervals of milliseconds (phasic alertness), and the other over minutes or even hours (tonic alertness or sustained attention). In order to evaluate individual capacities for sustained attention and phasic alertness, most studies rely on variations of the Continuous Performan...
