Show Answer

Correct Answer � B
Explanation
|
|
Ans: B. NREM
- EEG in “B” shows high amplitude, low-frequency waves as compared to waves A and C and EOG and EMG are nearly flat when compared to A. In C also they are flat.
- In NREM stage-4 delta waves are seen. So high amplitude, low frequency (delta waves) is seen in NREM.
- In quiet wakefulness and awake state, alpha waves (high frequency, low amplitude) are seen. In REM sleep, beta waves (high frequency, low amplitude) are seen.
