IBC (Individual Brain Charting)
Introduced by Bazeille et al. in An empirical evaluation of functional alignment using inter-subject decoding
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
