brain waves
EEG's detection target
Brain waves are rhythmic electrical impulses produced by the brain, detectable by electroencephalography.
Different frequencies indicate different mental states—delta waves during deep sleep, beta waves during alert concentration.
Figuratively, brain waves are sudden ideas or inspirations: I had a brain wave and figured out how to fix it.
