Dataset for the single case described in the paper  CORTEX-D-23-00454R1 "Obrenovic M, Mouthon M, Chavan C, Saj A, Dieguez S, Aellen J, Chabwine JN. Acute right opercular stroke-associated polyopic heautoscopy and hallucinations caused by disconnexion to the inferior parietal lobule through the superior longitudinal fasciculus III: a single case study. Cortex"It contains two separate folder for this case: 1. behavour: Folder which contains the details clinical and investigation report (in French and English) as well as the Neuropsychological test answer of the patient.2. MRI: Folder which contains the MRI images. You will find brain anatomical scans (T1w, T1w with contrast agent, T2w, FLAIR and dwi images) as well as the diffusion imagery (Diffusion tensor tractography). Here you can find the abstract of the paper:Illusory neuropsychiatric symptoms such as hallucinations or the feeling of a presence (FOP) can occur in diffuse brain lesion or dysfunction, in psychiatric diseases as well as in healthy individuals. Their occurrence due to focal brain lesions is rare, most probably due to underreporting, which limits progress in understanding their underlying mechanisms and anatomical determinants.In this single case study, an 86-year-old patient experienced, in the context of an acute right central opercular ischemic stroke, visual hallucinatory symptoms (including palinopsia), differently lateralized auditory hallucinations and FOP. This unusual clinical constellation could be precisely documented and illustrated while still present, allowing a realistic and immersive visual experience validated by the patient. The acute stroke appeared to be their most plausible cause (after exclusion of other etiologies). Furthermore, accurate analysis of tractographic data suggested that disruption in the posterior bundle of the superior longitudinal fasciculus connecting the stroke lesion to the inferior parietal lobule was the anatomical substrate explaining all illusory symptoms, in coherence with existing literature. We could finally elaborate on symptoms taxonomy and phenomenology (e.g. polyopic heautoscopy, hallucinatory FOP, etc), and on patient’s remarkable distancing from them (with some therapeutic implications supported by plausibly engaged mechanisms).This case not only authentically enriched the description of such rare combination of heterogenous illusory symptoms through this novel visualization-based reporting approach, but disclosed an unrevealed anatomo-clinical link relating all of them to the acute stroke lesion through an association fiber, thereby contributing to the understanding of these intriguing symptoms and their determinants.

Theories of embodied cognition postulate that language processing activates similar sensory-motor structures as
when interacting with the environment. Only little is known about the neural substrate of embodiment in a
foreign language (L2) as compared to the mother tongue (L1). In this fMRI study, we investigated embodiment of
motor and non-motor action verbs in L1 and L2 including 31 late bilinguals. Half had German as L1 and French as
L2, and the other half vice-versa. We collapsed across languages to avoid the confound between language and
order of language acquisition. Region of interest analyses showed stronger activation in motor regions during L2
than during L1 processing, independently of the motor-relatedness of the verbs. Moreover, a stronger involvement
of motor regions for motor-related as compared to non-motor-related verbs, similarly for L1 and L2, was
found. Overall, the similarity between L1 and L2 embodiment seems to depend on individual and contextual
factors.

fMRI dataset of 91 participants during a linguistic task about language stress perception in a foreign language. Participants listened to pairs of words in a foreign language (Spanish) and had to indicate if the words were the same or different. The different pairs differed either by the stress pattern, or by the final vowel. This dataset was divided into two groups: 51 participants with French as native language and 40 with Swiss-German as native language. None of the participants had knowledge of Spanish. This repository respects the BIDS standard (https://bids.neuroimaging.io/), including all the raw data (func, fmap, anat) and metadata in order to reproduce the processing. These data have been used in two papers: S. Schwab, M. Mouthon, L.B. Jost, J. Salvadori, I. Yakoub, E. Ferreira da Silva, N. Giroud, B. Perriard and J.M. Annoni, Neural correlates of lexical stress processing in a foreign free-stress language; Brain and Behavior (2023) L. Rogenmoser, M. Mouthon, F. Etter, J. Kamber, J.M. Annoni and S. Schwab; The processing of stress in a foreign language modulates functional antagonism between default mode and attention network regions, (submitted)
