Neurosciences unlock the secret of the first abstract engravings
Long before Lascaux paintings, humans engraved abstract motifs on stones, shells or egg shells. the earliest are 540,000 years old. For the archaeologists who discovered these objects, the question is whether they are the result of unpurposive behaviour, the simple Lire plus …

In search of the genetic basis of the cerebral lateralization of language through an innovative alliance between functional imaging and full genome sequencing
For the vast majority of human beings, it is the left hemisphere of the brain that is dominant for various aspects of language processing. Only less than 1% of the adult population has an atypical inverted dominance of their right Lire plus …
Rather left brain or right brain?
A study conducted by Slava Karolis, Maurizio Corbetta and Michel Thiebaut de Schotten at the National centre for scientific research (CNRS) in France and the University of Padova in Italy was recently published in the journal Nature Communication. The authors Lire plus …
Nathalie Tzourio-Mazoyer among the women scientists of a photographic exhibition in the Basque Country
Worker Science is a project created by Teknahi to show realistically and closely working women in the world of science. The exhibition is a pilot sample of this international project, fruit of the collaboration between Teknahi and the Okendo Cultural Centre, which offers the public the possibility of getting closer to the day-to-day life of working women who do science in our society.
It is a proposal accessible to all audiences, thanks to the opposing visions of photographers Elba Martínez and Javier Domínguez, along with audiovisuals, infographics, texts and thematic showcases that will help us understand and enjoy the world of science, so present, so distant, and women who with their effort and knowledge improve our world every day, trying to make it less ignorant, less superstitious and less dark.
SENSAAS, a new atlas of the brain’s language areas
The GIN has just developed a new brain atlas of cortical areas of language integration. It will be particularly useful for cohort studies looking for the genetic bases of language regions or on the neuroanatomical changes associated with language pathology. Lire plus …
How to study structure-function relationships in the cerebral cortex? The development of new neuroimaging markers is a promising solution.
The Planum Temporale (PT) is a region of the temporal lobe involved in processing language sounds that has a larger surface area in the left cerebral hemisphere than in the right. Geschwind, who discovered this asymmetry in 1968, had proposed Lire plus …
Michel Thiebaut de Schotten, winner of a prestigious European Research Council Fellowship, will join GIN-IMN on September 1st, 2019
CNRS Bronze medalist for 2018, Michel Thiebaut de Schotten is Director of Research in neuropsychology and brain connectivity neuroimaging. His arrival at GIN-IMN, long-time planed, is scheduled for September 1st, 2019. Winner of the prestigious European Research Council Fellowship « Lire plus …

Is the planum temporale surface area a marker of hemispheric or regional language lateralization?
In 1968, Geschwind discovered that the planum temporale (PT), a temporal lobe region involved in language sounds processing, had a larger surface area in the left hemisphere than in the right. Because language is hosted by the left hemisphere in Lire plus …
The reliability of anatomical connectivity data of the human brain challenged by 20 international teams of research in diffusion imaging and tractography
Diffusion magnetic resonance imaging (dMRI) is used to reveal in vivo the white matter bundles of the human brain by measuring the diffusion of water molecules, especially along axons. It is then possible by tractography to reconstitute step by step the Lire plus …
Nathalie Tzourio-Mazoyer participated in the forum “Science, Recherche et Société”
Sciences & Avenir and La Recherche organized for two days in September 2017 the Forum “Science, Recherche et Société” in the Cité des Sciences et de l’Industrie in Paris. On the agenda: four plenary lectures, eight round tables, and some Lire plus …
Using supervised learning to predict hemispheric dominance for language production
A Support Vector Machine (SVM) classifier predict patterns of hemispheric language dominance We used a Support Vector Machine (SVM) classifier to assess hemispheric pattern of language dominance of 47 individuals categorized as non-typical for language from their hemispheric functional laterality Lire plus …
The GIN-IMN presents its recent results at NeuroFrance 2017
The NeuroFrance 2017 Congress took place from Wednesday 17 to Friday 19 May at the Palais des Congrès in Bordeaux. The GIN-IMN featured scientific posters during the 3-days event. You will find these posters below. Wednesday 17th May Reliability of Lire plus …
Travel of Iseult, the largest and most powerful MRI magnet in the world
On Thursday, May 4, a giant magnet weighing 130 metric tons will leave the assembly plants in Belfort on its journey to the NeuroSpin research facility at the CEA’s Paris-Saclay Center (Essonne). The cutting-edge magnet, which will generate a magnetic Lire plus …
Variations of planum temporale asymmetries with Heschl’s Gyri duplications and association with cognitive abilities
In healthy individuals, as in dyslexics, the left asymmetry of a temporal area involved in the processing of language sounds is associated with better verbal performances. This finding was made possible by taking account of individual anatomical variability in a Lire plus …
When spatial attention is associated with hemispheric lateralization
The objective of this study was to validate a line bisection judgement (LBJ) task for use in investigating the lateralized cerebral bases of spatial attention in a sample of 51 right-handed healthy participants. Using functional magnetic resonance imaging (fMRI), the Lire plus …
Right hand or left hand ?
Asymmetries of the motor cortex during the lateral judgment in fMRI In front of a photograph of hand, how do you decide that it depicts a right hand or a left hand? It is admitted that this judgment of laterality Lire plus …
AAL: a human brain atlas ranked second in the “top 100 cited” CEA publication
