Surprisingly Complex Waves Reveal the Brain’s Inner Workings

The brain operates using electrical activity to perform everyday tasks like navigation, memory, and decision-making.

About half of the brain's energy is spent maintaining electrochemical gradients in neurons, allowing them to fire rapidly when needed.

This electrical activity creates waves that travel across brain regions, similar to waves in a stadium where spectators raise their arms in sequence.

Traditionally, these waves were thought to be simple oscillations, like the sound of an engine running, but new research shows they are far more complex and play a central role in brain function.

Miller, a cognitive neuroscientist at MIT, notes that recent work is shifting the understanding of these waves from being mere background noise to being a fundamental way the brain processes information.
