IRM fonctionnelle

2023
La mesure de l’activité et de la connectivité cérébrale est désormais rendue possible par l’IRM fonctionnelle (IRMf) dont les principes sont résumés dans ce chapitre. Par contraste BOLD, basé sur des mécanismes neurovasculaires, ou par diffusion, reflétant les changements induits au niveau même du neuropile, l’IRMf permet une exploration des processus ...
