A novel 15-network parcellation from fMRI data in 15 intensively sampled participants

DU15NET-Prior: The 15-network group prior used in the MS-HBM model is made available as the DU15NET-Prior atlas. For many purposes this atlas can function and be utilized in group-based studies as an update to the prior “Yeo2011” atlases with refinements that reflect our current understanding of human cerebral network organization. The DU15NET-Prior utilizes the HCP data processed via their standard processing pipelines, and thus also has the benefit of being derived from data collected and registered with a commonly used set of pipelines.

DU15NET-Consensus: A consensus map represents the assignment at each vertex to the most common network among the 15 individuals collected here. No vertex is left unassigned. The DU15NET-Consensus atlas differs from the DU15NET-Prior in that it reflects the idiosyncratic features and spatial registrations of the data from the present participants, including small regions that are absent in the group-averaged estimates. For example, there is a clear representation of the SAL / PMN network in medial prefrontal cortex.

DU15NET-Agree53per: This agreement map is thresholded to leave only vertices with agreement across participants of n ≥ 8 (53%). The agreement atlases may be most useful when the goal is to construct regions-of-interest that have a high probability of being in one network and not another, in situations where it is appropriate to have regions that cover a portion of the cerebral cortex not the cortex in its entirety.

DU15NET-Agree80per: This agreement map is thresholded to leave only vertices with agreement across participants of n ≥ 12 (80%).

DU15NET-AgreeProb: The final provided atlas represents the probability at each vertex that, within the present 15 participant sample, the same network is assigned across individuals.
