A theory published September 1, 2026 in The Journal of Neuroscience by three scientists at MIT's Picower Institute for Learning and Memory proposes that traveling waves of rhythmic neural activity coordinate networks of neurons and support analog computations. Senior author Earl K. Miller argues that physically connected circuits and synapses are fundamental but incomplete as an explanation, because the brain needs a faster control system to use stored knowledge in rapidly changing sensory contexts. The authors frame brain waves as performing that coordinating role, citing years of experimental evidence from Miller's lab and others.

The paper argues that waves of different frequencies organize neural ensembles: slower alpha and beta waves, representing memories and goals, regulate faster gamma waves carrying sensory information. It cites evidence that waves can influence neural spiking rapidly through electric fields, a process called ephaptic coupling, and can act both locally and as traveling patterns across the cortex. Consciousness, the authors propose, emerges when these wave patterns bring the cortex into an organized, globally integrated state; they point to anesthesia studies in which different drugs similarly disrupted wave dynamics.

Miller describes the work as a theory, saying the lab aims to test it by looking for signatures of analog computation in brain wave patterns. The authors also suggest wave dynamics could be relevant to clinical treatment, noting waves can be manipulated non-invasively. The paper is a proposed explanation, not an established proof or consensus.
