Surprisingly Complex Waves Reveal the Brain's Inner Workings

Recent research reveals that brain waves are far more complex than previously understood, exhibiting diverse patterns including source waves, sink waves, and spiral vortexes rather than simple oscillations. These traveling waves across the cortex appear to play a central role in brain function, potentially reorganizing neural activity in real-time to meet behavioral demands within seconds. Different tasks are associated with distinct wave patterns, suggesting these waves are a major mechanism through which the cortex processes information.
