Question

Large, slow brain waves called Delta waves are most associated with which stage of sleep?

Answer 1

Stage 4 for A P E X test

Step-by-step explanation:

Answer 2

Deep stage 3 of NREM

Step-by-step explanation:

• Delta waves are a type of waves that are recorded in an EEG and has a frequency of 0.5 to 4 Hertz.
• These waves are known detected during the deep stage 3 of NREM and hence this stage is also known as slow wave sleep.
• Out of all the brain waves that are detected during an EEG, these waves are the ones with the highest amplitude and the slowest in nature .
• These waves are detected first at stage 3 and then dominates the stage 4 of the sleep.
• Since it is in the stage 3 that these waves are detected, the sleep during this stage is also known as delta sleep.
