Individual Brain Charting third release, probing brain activity during Movie Watching and Retinotopic Mapping

Abstract

The Individual Brain Charting (IBC) is a multi-task functional Magnetic Resonance Imaging dataset acquired at high spatialresolution, which is intended to facilitate the cognitive mapping of the human brain. It consists in the deep phenotyping of twelve individuals in a fixed environment, covering a broad range of psychological domains that allows, in turn, the investigation of atlasing techniques in functional neuroimaging. Here, we present the inclusion of task data from both naturalistic stimuli and trial-based designs, to uncover core structures of brain activation. We rely on the Fast Shared Response Model (FastSRM): an analytical tool that provides a data-driven solution to model naturalistic stimuli, typically containing many features. We show that data from left-out runs can be reconstructed using FastSRM, thus enabling the extraction of functional networks pertaining to vision, audio and language systems. We also present an in-depth study of the topographic organization of the visual system through a retinotopy task. IBC is open access: source plus derivatives imaging data and meta-data are available in public repositories.
