Question: 1 / 400

What brain wave is primarily associated with relaxed wakefulness?

Delta waves

Alpha waves

The brain wave primarily associated with relaxed wakefulness is Alpha waves. These waves typically occur when a person is awake but in a state of relaxation, such as during meditation, daydreaming, or when one is peacefully resting with their eyes closed. Alpha waves have a frequency range of approximately 8 to 12 Hz and are indicative of a calm, alert state of mind.

This state contrasts with other types of brain waves: Delta waves are associated with deep sleep and have a low frequency (1 to 4 Hz), Theta waves are often linked to light sleep, deep relaxation, or creativity (4 to 8 Hz), and Gamma waves are associated with high-level information processing, problem-solving, or intense concentration (above 30 Hz). Thus, Alpha waves uniquely reflect the specific state of relaxed wakefulness, making them the correct answer in recognizing different brain wave states.
