Topic: Laplacian dynamics

Sensory, cognitive, and motor functions rely on transmission/integration of signals across multiple spatiotemporal scales which are fundamentally constrained by neuroanatomy. Uncovering connectivity patterns that shape signal propagation is thus of central importance to understanding brain computations. An organizational principle of the brain is anatomical/functional hierarchy, often conceptualized as signals propagating up from sensory areas to cognitive areas and down to motor areas. However, to determine if such a hierarchy is a sequential (e.g., MLP) or parallel (e.g., U-net) architecture
