That work, published in Radiation Research, lays a path for the use of diffusion imaging for the early detection of neurological abnormalities resulting from different types of stress.

Characteristics of the initial symptoms of Alzheimer's disease in young patients

Thu, 10 Jun 2021 10:00:00 GMT

Researchers from BioMaps (SHFJ) and the Department of Memory and Language Neurology (Ste Anne's Hospital) studied the early clinical signs of Alzheimer's disease (AD) reported by young patients (< 62 years old) compared to those reported in classic AD of the elderly (> 65 years old). They show that these signs are misleading and often appear in the professional context.

PET imaging reveals the neuropharmacology of buprenorphine

Wed, 05 May 2021 10:00:00 GMT

Researchers at BioMaps (SHFJ) have succeeded in determining the interaction dynamics of buprenorphine, an opioid drug with a particularly complex pharmacology, with its brain receptors in vivo. To do so, they developed an original PET imaging approach based on the use of the radiolabeled molecule (11C-buprenorphine).

Humans Share an Exceptional Sense of Geometry

Fri, 23 Apr 2021 10:00:00 GMT

Research from CEA, Collège de France, CNRS and Université Paris 8 shows that humans share a universal ability to understand abstract geometric concepts. This human ability does not depend on age, culture or education, but does not exist in the non-human primates tested. PNAS has just published their results.

Brain sulci imaging and genetics: the UK Biobank cohort has spoken.

Mon, 19 Apr 2021 10:00:00 GMT

Researchers from NeuroSpin and CNRGH (Jacob Institute) have studied, on a genome-wide scale, the potential associations of haplotypes (set of variants located side by side on a chromosome) with the opening value of imaged brain sulci, indicator of brain aging, from the UK Biobank neuroimaging-genetics cohort.

Aloïse Mabondzo receives exceptional funding from NIH !

Mon, 29 Mar 2021 10:00:00 GMT

Aloïse Mabondzo, research director, head of the Neurovascular Pharmacology Group of the SPI (DMTS), co-founder and scientific director (CSO) of CERES BRAIN THERAPEUTICS, has just obtained funding of nearly one million US dollars from the prestigious National Institute of Health for his project « Neuroprotective Strategy: Novel Purine Derivatives for Neonatal Hypoxia-ischemia ».

Metabolomics for the clinician and the development of a neuroprotective strategy in acute stroke

Thu, 04 Feb 2021 11:00:00 GMT

The TIRO team (SHFJ), in collaboration with the neurovascular clinicians of the Nice and Marseille University Hospitals, carried out analyses of the metabolome of cerebral clots at the origin of the occlusion of a cerebral artery responsible for a cerebral vascular accident (stroke). A pilot study that improved the understanding of the complex relationship between blood glucose levels and patients' functional prognosis.

Towards a transcranial echography

Tue, 19 Jan 2021 11:00:00 GMT

Jean-Luc Gennisson (BioMaps/SHFJ) coordinated, in partnership with the CEA-List (Sylvain Chatillon), the EchoBrain project (ATTRACT/H2020) aimed at adapting the digital tools developed by the List (CIVA platform) to significantly increase the quality of brain echography images, simple alternative compared to the methods (MRI, X-ray scanner) currently used for the diagnosis of strokes.

Launch of AROMA, a european project to exploit the full potential of NeuroSpin's future 11.7 T scanner.

Wed, 06 Jan 2021 11:00:00 GMT

AROMA, a FET-Open H2020 project, aims to develop the methodology necessary for the optimal operation of the future 11.7 T MRI being installed at NeuroSpin. This 5-year project, coordinated by Nicolas Boulant (NeuroSpin), with an overall budget of 3.6 million euros, involving six partners from five countries representing academia and industry, started on January 1, 2021.

An atypical cerebral organization for language

Wed, 09 Dec 2020 11:00:00 GMT

Researchers from the Neurofunctional Imaging Group (GIN, NeuroSpin, Bordeaux) studied by functional MRI, the organization of the brain network of sentence processing in individuals "atypical" for language, i.e. with a major role of the right hemisphere.
