SNAKE-fMRI: A modular fMRI data simulator from the space-time domain to k-space and back

Autor: Comby, Pierre-Antoine, Vignaud, Alexandre, Ciuciu, Philippe

We propose a new, modular, open-source, Python-based 3D+time fMRI data simulation software, \emph{SNAKE-fMRI}, which stands for \emph{S}imulator from \emph{N}eurovascular coupling to \emph{A}cquisition of \emph{K}-space data for \emph{E}xploration of

Pneumothorax revealing late recurrence of infantile myofibromatosis

Autor: Clemence Yguel, Jean Michel Vignaud, Angelica Tiotiu

Publikováno v: Annals of Thoracic Medicine, Vol 19, Iss 4, Pp 290-292 (2024)

Adult recurrence of infantile myofibromatosis is exceptional. Here, we report the case of a 23-year-old woman with a late recurrence of infantile myofibromatosis revealed by spontaneous pneumothorax. The chest computed tomography scan found both cavi

Evidence for chiral supercurrent in quantum Hall Josephson junctions

Autor: Vignaud, Hadrien, Perconte, David, Yang, Wenmin, Kousar, Bilal, Wagner, Edouard, Gay, Frédéric, Watanabe, Kenji, Taniguchi, Takashi, Courtois, Hervé, Han, Zheng, Sellier, Hermann, Sacépé, Benjamin

Publikováno v: Nature 624, 545 (2023)

Hybridizing superconductivity with the quantum Hall (QH) effects has major potential for designing novel circuits capable of inducing and manipulating non-Abelian states for topological quantum computation. However, despite recent experimental progre

Iron load in the normal aging brain measured with QSM and R2* at 7T: findings of the SENIOR cohort

Autor: Miguel Guevara, Stéphane Roche, Vincent Brochard, Davy Cam, Jacques Badagbon, Yann Leprince, Michel Bottlaender, Yann Cointepas, Jean-François Mangin, Ludovic de Rochefort, Alexandre Vignaud

Publikováno v: Frontiers in Neuroimaging, Vol 3 (2024)

BackgroundIron accumulates in the brain during aging and is the focus of intensive research as an abnormal load, particularly in Deep Gray Matter (DGM), is related to neurodegeneration. Magnetic Resonance Imaging (MRI) metrics such as Quantitative Su

Human brain representations of internally generated outcomes of approximate calculation revealed by ultra-high-field brain imaging

Autor: Sébastien Czajko, Alexandre Vignaud, Evelyn Eger

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-12 (2024)

Abstract Much of human culture’s advanced technology owes its existence to the ability to mentally manipulate quantities. Neuroscience has described the brain regions overall recruited by numerical tasks and the neuronal codes representing individu

When electrons populate a flat band their kinetic energy becomes negligible, forcing them to organize in exotic many-body states to minimize their Coulomb energy. The zeroth Landau level of graphene under magnetic field is a particularly interesting
