Question

match each stage of sleep to the brain waves that dominate brain activity at that stage.
stage 1
stage 2
stages 3 and 4
choose
alpha and theta
delta
theta
choose

Explanation:

• Stage 1 sleep is the transition from wakefulness to sleep, where brain activity shifts from wakeful alpha waves to slower theta waves, so both alpha and theta dominate.
• Stage 2 sleep is a deeper light sleep stage where theta waves are the primary dominant brain wave activity.
• Stages 3 and 4 (deep sleep, slow-wave sleep) are characterized by high-amplitude, slow delta waves that dominate brain activity.

Answer:

• Stage 1: alpha and theta
• Stage 2: theta
• Stages 3 and 4: delta
