Webb12 apr. 2024 · This disagreement might be due to the fact that ours is a model of inter-cortical wave propagation, whereas it has been argued that travelling waves in the scalp are mediated by an intra-cortical mechanism . In fact, travelling waves in the cortex are usually observed not at the whole-brain level but localized in smaller regions [5, 75, 76].
