MIA: An open-source toolbox for Multi-patient Intracranial EEG Analysis

Intracranial EEG (iEEG) performed during the pre-surgical evaluation of refractory epilepsy provides a great opportunity to investigate the neurophysiology of human cognitive functions with exceptional spatial and temporal precisions. A difficulty of the iEEG approach for cognitive neuroscience, however, is the potential variability across patients in the anatomical location of implantations and in the functional […]

Cross-linguistic gender effects in novice L2 learners

French speakers learned a limited vocabulary in Brazilian Portuguese via computerized games. Learned nouns either shared gender across languages or not. Pre-training, no ERP differences were found in a cross-modal match-mismatch task for match vs. mismatch trials. Post-training, an N400 effect was found for mismatch trials, but only when the grammatical gender of the learned […]

Hippocampal and auditory contributions to speech segmentation

We used frequency-tagging analysis to quantify the neuronal synchronization between the hippocampus and auditory regions, on the one hand, and the temporal structure of words and syllables of an artificial speech stream, on the other hand (A). Intracranial recordings in the hippocampus and auditory cortex (B) show that auditory regions are highly responsive to syllable […]

Temporally resolved neural dynamics underlying handwriting

    EEG time-courses were co-registered with handwriting movements produced on a tablet (top). When participants write words to dictation, a structured and reliable pattern of neural activation is associated with each writing stroke (bottom). The rhythm of handwriting is synchronised to the phase of theta brain oscillations, with a stronger synchronisation when participants write […]

MaSCoPin

  The students of the Master 1 in Cognitive Sciences have a friendly Christmas tree they call “MaSCoPin”. It is characterized by a mixture of vegetable and cortical elements and by the brilliance of its classic language areas. Thanks for the good mood and thanks for sharing!     L’amical sapin de Noël des étudiant·e·s […]

Linguistic et neuro-physiological comparison of human-human and human-robot conversations

A body of natural conversations helped develop lexical alignment between participants and two types of interlocutors: a human and a robot. fMRI data indicates a negative correlation of this alignment with cingulate cortex activity, suggesting a reduction in internal resource use when the participant’s lexicon is aligned to that of the speaker Hallart, C., Maes, […]
