Topic: multi-task representations

Hierarchical cortical organization unifies the brain’s structural and functional organization, yet its relationship to task-evoked cognitive processes remains unclear. How might intrinsic hierarchical properties shape and constrain the cognitive processes required to perform the wide variety of tasks encountered in daily life? By analyzing a human functional magnetic resonance imaging (fMRI) data set with 26 unique cognitive tasks collected per participant, we characterized the geometry and topography of multi-task representations across the cortical hierarchy using representational similarity
