Select one:
a. beta waves.
b. delta waves.
c. alpha waves.
d. theta waves.

Answer 1

During the deepest sleep, the brain produces delta waves, which have low frequency and high amplitude, and are associated with stage 3 NREM sleep.

Step-by-step explanation:

During the deepest sleep, our brain produces delta waves. These are low frequency, high amplitude brain waves that are characteristic of stage 3 non-REM (NREM) sleep, often referred to as deep sleep or slow-wave sleep. Delta waves have the lowest frequency and highest amplitude of our sleep brain wave patterns. This stage of sleep is crucial for restorative processes and it is much more difficult to awaken someone from sleep as they typically will have a decreased rate of respiration and a lowered heart rate during this phase.
