IBC (Individual Brain Charting)

The Individual Brain Charting (IBC) project aims at providing a new generation of functional-brain atlases. To map cognitive mechanisms in a fine scale, task-fMRI data at high-spatial-resolution are being acquired on a fixed cohort of 12 participants, while performing many different tasks. These data—free from both inter-subject and inter-site variability—are publicly available as means to support the investigation of functional segregation and connectivity as well as individual variability with a view to establishing a better link between brain systems and behavior.

** What’s special about the IBC dataset?**

• Taskwise dataset: spanning the cognitive spectrum within subject
• Fixed cohort over a 10-year span to minimize inter-subject variability
• Fixed experimental setting to minimize inter-site variability
• Multimodal: fMRI (task-based and resting state), DWI, structural

** Main characteristics **

• 12 healthy participants (aged 27-40 at the time of recruitment)
• Spatial resolution: 1.5mm (isotropic); Temporal resolution: 2s
• Scanner: Siemens 3T Magnetom Prisma; Coil: 64-channel
• 50 acquisitions per participant upon completion of the dataset in 2022
