Coarse and Fine N1 Tuning for Print in Younger and Older Chinese Children: Orthography, Phonology, or Semantics Driven?
This study aimed to investigate whether two groups of Chinese children could discriminate characters/character-like stimuli from visual controls (i.e., coarse N1 tuning) and distinguish characters from character-like stimuli (i.e., fine N1 tuning). We also explored the cognitive-linguistic correlates of N1 tuning. Seventeen children in the younger group (M = 7.7 years) and 13 in the older group (M = 9.4 years) were all required to finish a character decision task with character, pseudocharacter, noncharacter, and stroke combination conditions using ERP testing. Both the pseudocharacters and noncharacters were unpronounceab...

Artificial grammar learning in vascular and progressive non-fluent aphasias
Publication date: Available online 24 August 2017 Source:Neuropsychologia Author(s): Thomas E. Cope, Benjamin Wilson, Holly Robson, Rebecca Drinkall, Lauren Dean, Manon Grube, P. Simon Jones, Karalyn Patterson, Timothy D. Griffiths, James B. Rowe, Christopher I. Petkov Patients with non-fluent aphasias display impairments of expressive and receptive grammar. This has been attributed to deficits in processing configurational and hierarchical sequencing relationships. This hypothesis had not been formally tested. It was also controversial whether impairments are specific to language, or reflect domain general deficits in pr...

Voxel-based Lesion Analysis of Brain Regions Underlying Reading and Writing
Publication date: Available online 20 March 2018 Source:Neuropsychologia Author(s): Juliana V. Baldo, Natalie Kacinik, Carl Ludy, Selvi Paulraj, Amber Moncrief, Vitória Piai, Brian Curran, And Turken, Tim Herron, Nina F. Dronkers The neural basis of reading and writing has been a source of inquiry as well as controversy in the neuroscience literature. Reading has been associated with both left posterior ventral temporal zones (termed the “visual word form area”) as well as more dorsal zones, primarily in left parietal cortex. Writing has also been associated with left parietal cortex, as well as left sensorimotor cor...

Silent pauses in aphasia
Publication date: Available online 7 April 2018 Source:Neuropsychologia Author(s): Georgia Angelopoulou, Dimitrios Kasselimis, George Makrydakis, Maria Varkanitsa, Petros Roussos, Dionysis Goutsos, Ioannis Evdokimidis, Constantin Potagas Pauses may be studied as an aspect of the temporal organization of speech, as well as an index of internal cognitive processes, such as word access, selection and retrieval, monitoring, articulatory planning, and memory. Several studies have demonstrated specific distributional patterns of pauses in typical speech. However, evidence from patients with language impairment is sparse and res...

Is VLSM a valid tool for determining the functional anatomy of the brain? Usefulness of additional Bayesian network analysis
ConclusionsConventional VLSM analyses are sensitive but weakened by a type I error due to the combined effects of multicollinearity and lesion frequency. We demonstrate that the addition of a Bayesian network analysis, and to a lesser extent of logistic regression, controlled for this type I error and constituted a reliable means of defining the functional anatomy of the motor system in stroke patients.

Grey and white matter substrates of action naming
Publication date: Available online 23 May 2019Source: NeuropsychologiaAuthor(s): Yu Akinina, O.V. Dragoy, M.V. Ivanova, E.V. Iskra, O.A. Soloukhina, A.G. Petryshevsky, O.N. Fedinа, A. Turken, V.M. Shklovsky, N.F. DronkersAbstractDespite a persistent interest in verb processing, data on the neural underpinnings of verb retrieval are fragmentary. The present study is the first to analyze the contributions of both grey and white matter damage affecting verb retrieval through action naming in stroke. We used voxel-based lesion-symptom mapping (VLSM) with an action naming task in 40 left-hemisphere stroke patients. Within the ...

Re-learning and remembering in the lesioned brain
We report on two studies that examine whether or not these principles also apply in language re-learning and retention for individuals with acquired deficits in written language production. Study 1 compared distributed vs. clustered training schedules, while Study 2 examined—for the first time in the context of re-learning—the relationship between the spacing of training trials and retention period. This investigation revealed that, despite significant cognitive deficits and brain lesions, remarkably similar principles govern re-learning and retention in the lesioned brain as have been found to apply in neurologically ...

Disownership of body parts as revealed by a visual scale evaluation. An observational study
Publication date: Available online 7 January 2020Source: NeuropsychologiaAuthor(s): Roberta Ronchi, Michela Bassolino, Dragana Viceic, Anne Bellmann, Philippe Vuadens, Olaf Blanke, Giuseppe VallarAbstractThe disownership of body parts, that most frequently occurs on the left side of the body, contralateral to right-hemispheric lesions, is an infrequent disorder, as usually assessed by interviews asking for dichotomic “yes/no” responses. This observational study in right-brain-damaged stroke patients investigated the efficacy of a continuous Visual Analog Scale (VAS) to detect body disownership after right brain damage,...

Behavioral deficits in left hemispatial neglect are related to a reduction of spontaneous neuronal activity in the right superior parietal lobule
Publication date: Available online 20 January 2020Source: NeuropsychologiaAuthor(s): Björn Machner, Janina von der Gablentz, Martin Göttlich, Wolfgang Heide, Christoph Helmchen, Andreas Sprenger, Thomas F. MünteAbstractFocal brain lesions may induce dysfunctions in distant brain regions leading to behavioral impairments. Based on this concept of ‘diaschisis’, spatial neglect following stroke has been related to structural damage of the right-lateralized ventral attention network (VAN) and disrupted inter-hemispheric functional connectivity (FC) in the bilateral dorsal attention network (DAN). We questioned whether n...

Left frontal aslant tract and lexical selection: Evidence from frontal lobe lesions
Publication date: Available online 10 February 2020Source: NeuropsychologiaAuthor(s): Andrey Zyryanov, Svetlana Malyutina, Olga DragoyAbstractThe frontal aslant tract (FAT) is a white-matter tract connecting the inferior frontal gyrus (IFG) and the supplementary motor complex (SMC). Damage to either component of the network causes spontaneous speech dysfluency, indicating its critical role in language production. However, spontaneous speech dysfluency may stem from various lower-level linguistic deficits, precluding inferences about the nature of linguistic processing subserved by the IFG-SMC network. Since the IFG and the...

Preserved mid-fusiform activation for visual words in a patient with a visual word recognition impairment
Publication date: December 2014 Source:Neuropsychologia, Volume 65 Author(s): Suzanne E. Welcome , Adrian Pasquarella , Xi Chen , David R. Olson , Marc F. Joanisse Previous functional imaging studies have highlighted the role of left ventral temporal cortex in processing written word forms. We explored activation and anatomical connectivity of this region in HE, a professional writer with alexia as a result of stroke affecting primarily white matter in the left inferior temporal lobe. We used a one-back visual recognition task and functional Magnetic Resonance Imaging to elicit automatic activation to various orthographi...

The role of prestimulus activity in visual extinction
Publication date: July 2013 Source:Neuropsychologia, Volume 51, Issue 8 Author(s): Maren Urner , Margarita Sarri , Jessica Grahn , Tom Manly , Geraint Rees , Karl Friston Patients with visual extinction following right-hemisphere damage sometimes see and sometimes miss stimuli in the left visual field, particularly when stimuli are presented simultaneously to both visual fields. Awareness of left visual field stimuli is associated with increased activity in bilateral parietal and frontal cortex. However, it is unknown why patients see or miss these stimuli. Previous neuroimaging studies in healthy adults show that presti...
