# Traveling Waves **Domain:** Neuroscience / Electrophysiology / Dynamical Systems **Doc Type:** Technical Concept Node **Maturity:** Established phenomenon; computational interpretation under active study **Related:** [[Analog Computation]], [[Ephaptic Coupling]], [[Effective Connectivity]], [[Electroencephalography]] --- ## Definition **Traveling waves** are organized patterns of neural oscillation whose phase and activity propagate across space in the brain. Unlike a synchronous rhythm treated as occurring everywhere at once, a traveling wave has a spatial trajectory and can therefore coordinate different cortical locations at different moments. ## Corpus Context [[articles/Analog Cognition and the Architecture of Continuity|Analog Cognition and the Architecture of Continuity]] treats traveling waves as a candidate fast-control layer: slower alpha and beta activity can regulate faster gamma activity across changing cortical locations without requiring immediate synaptic rewiring. ## Evidence Boundary Traveling neural waves are experimentally observed. The claim that interference among them constitutes analog computation is a separate, explicitly proposed hypothesis. ## Sources / Provenance - Earl K. Miller, Scott L. Brincat, and Jefferson E.
