LLMs: Impulses, Not Hierarchy, Explain Human Intelligence

There is a review, Hierarchy in the Organization of Brain Networks where the authors stated that hierarchy "is an intuitive and popular idea that the brain, and in particular the cerebral cortex, is organized into modular networks across many scales, from cellular circuits, cortical columns via nuclei or cortical areas to large-scale units such as the entire visual or sensory-motor cortex. At each level, nodes are more densely wired within than between the modules. While empirical data confirm this modular organization at some scales, for instance, for mesoscopic cortical connections, the detailed organization of brain networks across all scales is not yet experimentally accessible.
