brainwaves

Brainwaves are electrical impulses created by the brain’s activity, reflecting different states of consciousness such as alertness, relaxation, or sleep. These impulses produce rhythmic patterns called frequency bands, categorized as Delta (deep sleep), Theta (light sleep or relaxation), Alpha (calm alertness), Beta (active thinking), and Gamma (high-level processing). Each type indicates specific mental states and activities, and their balance influences mood, focus, and overall brain health. Measuring brainwaves through EEG helps understand brain function, diagnose conditions, or guide practices like meditation and neurofeedback.
