Answers and explanations

  1. Question: Which sleep stage is most strongly associated with vivid dreaming?
    Answer: REM sleep
    Explanation: REM sleep features rapid eye movements and high brain activity similar to wakefulness, producing the most vivid dreams; non-REM dreams are usually less narrative-driven.
  2. Question: What neurotransmitter system is suppressed during REM, facilitating dream occurrence?
    Answer: Noradrenergic
    Explanation: Reduced norepinephrine activity during REM permits the brain's vivid, unconstrained imagery; dopamine or serotonin reductions alone don't explain REM dreaming.
  3. Question: Which brain structure is crucial for forming the emotional content often seen in dreams?
    Answer: Amygdala
    Explanation: The amygdala drives emotional intensity in dreams and is highly active in REM; the hippocampus handles memory context, not primary emotion.
  4. Question: What term describes the phenomenon of acting out dreams due to loss of muscle atonia?
    Answer: REM behavior disorder
    Explanation: REM behavior disorder causes people to physically enact dreams because REM paralysis fails; it's distinct from sleepwalking which occurs in non-REM.
  5. Question: Which therapeutic technique uses dream recall and modification to reduce nightmare frequency?
    Answer: Imagery rehearsal
    Explanation: Imagery rehearsal therapy has patients rehearse a changed, nonthreatening ending to nightmares, effectively reducing occurrences; it's different from exposure therapy.
  6. Question: What phenomenon involves becoming aware within a dream and sometimes controlling it?
    Answer: Lucid dreaming
    Explanation: Lucid dreaming is conscious awareness during a dream and can include control; false memories or wakeful imagination are not the same.
  7. Question: Which theory proposes dreams help consolidate emotional memories by reprocessing them?
    Answer: Emotion consolidation
    Explanation: Emotion consolidation theory suggests dreaming integrates and downregulates emotional memories during sleep, unlike activation-synthesis which focuses on random neural firing.
