All Flashcards
Compare the Activation-Synthesis Theory and the Consolidation Theory of dreams.
Activation-Synthesis: Dreams are random neural firings. Consolidation: Dreams help process memories.
Compare NREM sleep and REM sleep.
NREM: Stages 1-3, decreasing brain activity. REM: Brain activity similar to wakefulness, rapid eye movements, muscle atonia.
Compare insomnia and narcolepsy.
Insomnia: Difficulty falling/staying asleep. Narcolepsy: Excessive daytime sleepiness and sudden sleep attacks.
Compare sleep apnea and somnambulism.
Sleep apnea: Breathing stops and starts during sleep. Somnambulism: Performing complex actions during deep sleep.
Compare Stage 2 and Stage 3 NREM sleep.
Stage 2: Sleep spindles and K-complexes. Stage 3: Delta waves, deep sleep.
What are the stages of sleep?
NREM Stage 1, NREM Stage 2, NREM Stage 3, REM sleep.
Describe the process of memory consolidation during sleep.
Brain replays and reinforces neural connections, moving them from short-term to long-term memory, especially during slow-wave and REM sleep.
Describe the progression of NREM stages during the night.
Stage 3 is longest in the first cycle and gets shorter later on.
Describe how REM sleep changes throughout the night.
REM sleep gets longer as the night goes on, with the longest periods in the second half of the night.
How does jet lag affect the circadian rhythm?
Traveling across time zones throws your rhythm off, causing a mismatch between your internal clock and the external environment.
How does shift work affect the circadian rhythm?
Working nights or rotating shifts messes with your natural sleep schedule, disrupting the SCN's regulation.
How can treating sleep disorders improve daytime functioning?
Treating sleep disorders and keeping a regular sleep schedule can improve your attention, reaction time, decision-making, and emotional regulation.
How can a regular sleep schedule improve overall well-being?
It helps maintain a healthy circadian rhythm, leading to better physical and mental health.
