Which EEG frequency is associated with alert wakefulness?

Explanation:
In EEG, different frequency bands reflect different brain states, with higher frequencies linked to more alert processing. The fast, higher-range activity characteristic of alert wakefulness is Beta, typically about 13 to 30 Hz, and it’s associated with active thinking, concentration, and arousal. In contrast, Alpha (roughly 8–12 Hz) appears in relaxed wakefulness (often with eyes closed), Theta (4–7 Hz) during drowsiness or light sleep, and Delta (0.5–4 Hz) during deep sleep. So, Beta is the frequency most closely tied to being alert and actively engaged.
