EBRAINS 2.0 - New funded Project! - Start: 01.01.2024 / Runtime: 3 years
The EBRAINS 2.0
project was submitted in response to the INFRASERV call (a Horizon Europe's Research Infrastructures actions) and was awarded €38 million to further develop the EBRAINS research infrastructure services, a legacy of the Human Brain Project.
The project involves 59 partner institutions from 16 European countries and officially started in January 2024. As partners, our group together with CompNeuro were granted €1.1 million.
