La microscopie de localisation ultrasonore pour voir la circulation sanguine comme jamais dans le cerveau

Les techniques d’imagerie qui permettent de voir différents aspects du cerveau humain, tant anatomiques que physiologiques, chez des sujets vivants sont autant d’exploits technologiques que d’inventivité scientifique. On en a un nouvel exemple avec la microscopie de localisation ultrasonore qui vient d’être utilisée pour la première fois pour visualiser la circulation sanguine cérébrale de façon dynamique à l’échelle du capillaire sanguin.
