Which of the following statements is true about NREM and REM sleep?

Question

BlackTom AI · Accepted Answer

Question at hand asks us to identify a true statement about NREM and REM sleep. 
Option 1: 'NREM sleep is divided into two stages, while REM sleep has four stages.' This is inaccurate. In modern sleep staging, NREM consists of two (N1 and N2) or three (N1, N2, N3) stages depending on the classification used, and REM sleep is not described as having four stages. The statement mismatches standard sleep architecture, so it is false. 
Option 2: 'REM sleep is associated with vivid dreaming and muscle paralysis.' This aligns with established knowledge: REM sleep is characterized by vivid dreams and atonia (loss of voluntary muscle tone), which prevents acting out dreams. This makes the option true. 
Option 3: 'NREM sleep includes Stage 4, which is the lightest stage of sleep.' This reflects an older nomenclature where Stage 4 existed as a separate deep sleep stage; in current classifications, Stage 4 is merged into N3 (deep NREM). As written, the claim is outdated and thus incorrect. 
Option 4: 'REM sleep is the deepest and most restorative sleep, helping with physical recovery.' This is a common misconception. REM sleep is important for memory consolidation and emotional processing, and while it serves many restorative functions, deep physical restoration is more associated with deep NREM (N3). Therefore, this statement is not accurate. 
Overall, evaluating each choice shows that only Option 2 accurately reflects true characteristics of REM sleep relative to NREM sleep, while the other statements contain inaccuracies or outdated framing.

24. Stage 3 sleep is characterized by: A. Beta waves B. Delta waves C. Sleep spindles D. Rapid eye movements

16. Stage 1 sleep resembles wakefulness because it shows: A. Delta waves B. Spindles and K-complexes C. Low amplitude, high frequency EEG D. Theta-suppression waves Answer: C. Low amplitude, high frequency EEG

When our brain waves are in the waves activity, one would be in stage one of sleep.

When we enter this stage of sleep, our brain waves change to theta waves.

In this stage of sleep, we are no longer responsive to the outside world and our sensory experiences drop.

Each stage of sleep is characterized by different types of brain wave patterns.
