This research article investigates the functional organization of the human brain by identifying shared connectivity patterns across the isocortex, cerebellum, and hippocampus. Using advanced gradient mapping on large neuroimaging datasets, the authors discovered that these seemingly distinct structures operate under a common systems-level framework. They identified two primary functional gradients that correspond across all three regions, suggesting a highly coordinated architecture for processing information. The study proposes that this structural alignment supports predictive processing, a computational theory where the brain constantly generates and updates internal models of the world. By demonstrating these robust, replicable links, the authors provide a new integrative foundation for understanding how different brain parts work together to regulate the body and mind.
