Embodied semantics in a second language: critical review and clinical implications

Monaco, Elisa ; Jost, Lea B. ; Gygax, Pascal M. ; Annoni, Jean-Marie

In: Frontiers in Human Neuroscience, 2019, vol. 13, p. -

The role of the sensorimotor system in second language (L2) semantic processing as well as its clinical implications for bilingual patients has hitherto been neglected. We offer an overview of the issues at stake in this under-investigated field, presenting the theoretical and clinical relevance of studying L2 embodiment and reviewing the few studies on this topic. We highlight that (a) the...

Auditory time perception in Huntington’s disease

Vez, S. ; Köhli, J. ; Frey, B. ; Magezi, David A. ; Annoni, Jean-Marie ; Burgunder, J.-M.

In: Neuropsychologia, 2018, vol. 119, p. 247–252

Huntington's disease (HD) is characterized by early involvement of the striatum. It affects the pace of repetitive motor activity, as motor timing depends on basal ganglia activity. However, data are lacking on the impact of this process on auditory time perception in motor non-affected gene carriers.Objective: This work aims to test the performance in time perception of a group of mutation...

Investigating post-stroke fatigue: An individual participant data meta-analysis

B.Cumming, Toby ; Yeo, Ai Beng ; Marquez, Jodie ; Churilov, Leonid ; Annoni, Jean-Marie ; Badaru, Umaru ; Ghotbi, Nastaran ; Harbison, Joe ; Kwakkel, Gert ; Lerdal, Anners ; Mills, Roger ; Naess, Halvor ; Nyland, Harald ; Schmid, Arlene ; Tang, Wai Kwong ; Tseng, Benjamin ; Port, Ingridvan de ; Mead, Gillian ; English, Coralie

In: Journal of Psychosomatic Research, 2018, vol. 113, p. 107–112

The prevalence of post-stroke fatigue differs widely across studies, and reasons for such divergence are unclear. We aimed to collate individual data on post-stroke fatigue from multiple studies to facilitate high-powered meta-analysis, thus increasing our understanding of this complex phenomenon.Methods: We conducted an Individual Participant Data (IPD) meta-analysis on post-stroke fatigue...

Multimodal communication in aphasia: perception and production of co-speech gestures during face-to-face conversation

Preisig, Basil C. ; Eggenberger, Noëmi ; Cazzoli, Dario ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Meichtry, Jurka R. ; Nef, Tobias ; Müri, René M.

In: Frontiers in Human Neuroscience, 2018, vol. 12, p. -

The role of nonverbal communication in patients with post-stroke language impairment (aphasia) is not yet fully understood. This study investigated how aphasic patients perceive and produce co-speech gestures during face-to-face interaction, and whether distinct brain lesions would predict the frequency of spontaneous co-speech gesturing. For this purpose, we recorded samples of conversations...

Dorsolateral prefrontal transcranial direct current stimulation modulates language processing but does not facilitate overt second language word production

Radman, Narges ; Britz, Juliane ; Buetler, Karin ; Weekes, Brendan S. ; Spierer, Lucas ; Annoni, Jean-Marie

In: Frontiers in Neuroscience, 2018, vol. 12, p. -

Word retrieval in bilingual speakers partly depends on executive-control systems in the left prefrontal cortex - including dorsolateral prefrontal cortex (DLPFC). We tested the hypothesis that DLPFC modulates word production of words specifically in a second language (L2) by measuring the effects of anodal transcranial direct current stimulation (anodal-tDCS) over the DLPFC on picture naming...

Age-related differences in cortical and subcortical activities during observation and motor imagery of dynamic postural tasks: an FMRI study

Mouthon, Audrey ; Ruffieux, Jan ; Mouthon, Michael ; Hoogewoud, Henri-Marcel ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Neural Plasticity, 2018, p. -

Age-related changes in brain activation other than in the primary motor cortex are not well known with respect to dynamic balance control. Therefore, the current study aimed to explore age-related differences in the control of static and dynamic postural tasks using fMRI during mental simulation of balance tasks. For this purpose, 16 elderly (72 ± 5 years) and 16 young adults...

Decision-making in multiple sclerosis patients: a systematic review

Neuhaus, Mireille ; Calabrese, Pasquale ; Annoni, Jean-Marie

In: Multiple Sclerosis International, 2018, p. -

Background. Multiple sclerosis (MS) is frequently associated with cognitive and behavioural deficits. A growing number of studies suggest an impact of MS on decision-making abilities. The aim of this systematic review was to assess if (1) performance of MS patients in decision-making tasks was consistently different from controls and (2) whether this modification was associated with cognitive...

Behavioral and electrophysiological signatures of word translation processes

Jost, Lea B. ; Radman, Narges ; A.Buetler, Karin ; Annoni, Jean-Marie

In: Neuropsychologia, 2018, vol. 109, p. 245–254

Translation is a demanding process during which a message is analyzed, translated and communicated from one language to another. Despite numerous studies on translation mechanisms, the electrophysiological processes underlying translation with overt production remain largely unexplored. Here, we investigated how behavioral response patterns and spatial-temporal brain dynamics differ in a...

Balance training reduces brain activity during motor simulation of a challenging balance task in older adults: an fMRI study

Ruffieux, Jan ; Mouthon, Audrey ; Keller, Martin ; Mouthon, Michaël ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Frontiers in Behavioral Neuroscience, 2018, vol. 12, p. -

Aging is associated with a shift from an automatic to a more cortical postural control strategy, which goes along with deteriorations in postural stability. Although balance training has been shown to effectively counteract these behavioral deteriorations, little is known about the effect of balance training on brain activity during postural tasks in older adults. We, therefore, assessed...
