For baby connectome study, we propose a “developing triple network” model based on our findings from precious longitudinal infant resting-state fMRI data, which extends previous “triple network model” to 0-2 years old, a pivotal period which we have little knowledge on. Our developmental model provides future study with key information on early functional connectivity. We found medial prefrontal area is growing apart and its long-range FC is growing together at different speeds in the first 2 years. We, for the first time, found a novel early developmental pattern with both local and long-range FC increases at 6-9 months but decreases afterwards, indicating pivotal neural pruning mechanism from system neuroscience view point.
