Which brainwaves are associated with a relaxed wakefulness transitioning into sleep?

The correct answer is associated with alpha waves, which play a significant role during the transition from relaxed wakefulness into sleep. Alpha waves are typically present when a person is awake but relaxed, often occurring when someone is resting quietly while their eyes are closed, but not yet asleep. These waves have a frequency range of 8-12 Hz and are indicative of a state of calm alertness.

As an individual begins to transition into sleep, alpha wave activity may diminish, giving way to theta waves, which are more characteristic of early sleep stages. This distinction highlights the significance of alpha waves in indicating a particular state where the mind is at ease—essentially a bridge between wakefulness and sleep.

Understanding these brainwave patterns is essential in grasping the sleep cycle, as each wave type corresponds to different states of consciousness, with alpha waves marking the onset of sleep.
