What brain activity is generally recognized during a relaxed state of awakeness?

In a relaxed state of wakefulness, the brain is typically characterized by the presence of alpha waves. These brain waves have a frequency range of about 8 to 12 Hz and are most prominent when an individual is awake but in a relaxed state, such as during meditation or when the eyes are closed but one is still awake. Alpha waves indicate a calm, alert state where the individual is not actively engaged in cognitive tasks but is instead in a more reflective or restful mode.

While delta waves are associated with deep sleep and theta waves are linked to light sleep or deep relaxation, gamma waves are related to higher-level cognitive functions such as problem-solving and active thinking. Thus, alpha waves are the correct response for identifying brain activity during relaxed wakefulness, as they reflect a state of restfulness while still being alert and awake.
