A team from NeuroSpin has recently published 3 papers that address the question of how we perceive time from a cognitive neuroscience perspective, using real-life temporal experiments, laboratory experiments and MEG brainwave measurements indicative of the passage of time, and that shed light on how the brain constructs our experience of lived time.
Researchers at NeuroSpin have recently published 3 articles in Magnetic Resonance in Medicine on their technological and methodological developments that will help meet the challenges of ultra-high field MRI for tomorrow's medical brain imaging.
NeuroSpin researchers map chimpanzee brain structural connectivity for the first time using diffusion MRI data. New image processing enabled them to create two atlases of deep and superficial white matter connectivity. A step towards a better understanding of the evolution of the hominid brain.
In a study published in Nature Communications, researchers from UNICOG and BAOBAB use high-field functional MRI to reveal the brain areas where the representations of quantities generated by a mental arithmetic operation are encoded.
In an article published in Nature Communications, researchers from the I2BC show that applying a fragmentation strategy to the protein partners of assemblies depending on intrinsically disordered regions very significantly improves AlphaFold2's prediction capacity.
Researchers at SIMoS (DMTS) describe the synthesis, engineering and evaluation of the properties of the B subunit of bacterial Shiga toxin (STxB), administered mucosally, as a vaccine tool. Their results confirm the value of using a synthetic STxB in an anti-tumor and anti-infectious vaccination strategy.
SHFJ researchers have validated the use of a new biomarker, the nonlinear shear modulus, to measure the elasticity of biological tissues, by comparing results obtained using echography with those obtained using MRI imaging and digital simulation. This biomarker is of particular interest for the diagnosis of certain breast cancers.
Les dispositifs tels que les lampes et les lunettes stroboscopiques censés faciliter la lecture des personnes dyslexiques n’auarient en fait aucun impact. C’est ce que révèle une étude menée par une équipe d’UNICOG (NeuroSpin) et publiée dans la revue Proceedings Royal Society.
Des chercheurs du SIMoS montrent que la combinaison de deux approches in silico et in vitro permet de sélectionner des anticorps thérapeutiques dont la fonctionnalité est préservée tout en diminuant le risque qu’ils induisent une réponse immunitaire indésirable.
I2BC researchers show that the Rif1 protein restrains the replication program and the recruitment of replication initiation factors during early embryonic divisions in X laevis. A step towards elucidating the molecular mechanisms involved in diseases resulting from Rif1 mutations in humans
In an article published in the journal Nucleic Acids Research, scientists from the I2BC, lPBS and the Institute for Structural and Chemical Biology (University of Leicester, UK) demonstrate how phytic acid, a product of cellular metabolism, stabilises the assembly of a complex enabling the repair of DNA breaks in humans.
In a review article published in Nature Neuroscience, researchers, including Florent Meyniel from UNICOG (NeuroSpin), show that the two dominant approaches to the neural representation of uncertainty are complementary and would benefit from being used synergistically.
In a study conducted by a team from the Marie Lannelongue Hospital, SPI researchers have established a difference between the metabolomic profiles of heart grafts harvested from pigs in a state of encephalic death or dead after controlled circulatory arrest. This work contributes to the exploration and validation of the use of hearts taken from people who have died after controlled circulatory arrest as a new source of grafts.
In an article in the New York Times, Stanislas Dehaene (NeuroSpin director) and Mathias Sablé-Meyer (PhD student) discuss recent results obtained in collaboration with the Collège de France, the CNRS and the University of Paris 8 that show that humans have a universal capacity to understand abstract geometric concepts.
September 2021, the 11.7 Tesla MRI of the Iseult project, the most powerful in the world for human imaging, has just unveiled its first images.
The European Commission once more places its trust on Multiwave company and its partners, Aix-Marseille Université , CEA and Université Catholique de Louvain to revolutionize ultra-high field magnetic resonance imaging of the brain.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
