Question

Alpha waves are seen during?

• A. Sleep
• B. REM movements
• C. Relaxed state
• D. Active state

Answer 1

The Correct Option is C

Alpha waves are brain waves that are typically seen when a person is in a relaxed and calm state, usually with closed eyes but not asleep. These waves are a type of neural oscillation in the frequency range of 8–12 Hz. They become more prominent when a person is awake, yet relaxed, and they diminish once the person becomes more involved in visual stimuli or stressful conditions.

Considering the provided options:

• Sleep: During sleep, especially in deep sleep stages, other types of brain waves, such as theta and delta waves, are more prominent.
• REM movements: REM (Rapid Eye Movement) sleep involves different brain activity patterns than alpha waves.
• Relaxed state: This is when alpha waves are most prevalent, as the mind is calm and not actively processing information or engaged in complex thought.
• Active state: In this state, beta waves (13–30 Hz) are more dominant, as they are associated with active thinking, problem solving, and decision making.

Thus, the correct answer is: Relaxed state.
