Stages
The frequency of waves released by your brain when you are awake and when in REM sleep is high. Making this stage 4 of sleep known as this.
What is paradoxical sleep?
Inability to sleep. Sleep deprivations.
What is insomnia?
Large muscles are paralyzed and immobile during this stage of sleep.
What is REM stage 4 sleep?
Our internal body clock that regulates a 24-hour cycle of sleep and wakefulness. Influenced by environment, stress, diet and physical factors.
What is circadian rhythm?
Biological & Information Processing suggests dreams help the brain consolidate our memories. This model suggests REM helps preserve and develop neural connections.
What is activation-synthesis model?
A state of relaxation as eyes begin to feel heavy and hypnagogic sensations (sense of falling or floating) are characteristic of this stage of sleep. Alpha waves are replaced with theta waves in the brain within this stage
What is NREM stage 1?
Insomnia deprives us of sleep and these important mental processes: Thinking, problem solving, memorization, executive decision making collectively known as this.
What is cognition?
This stage(s) are essential part of sleep for the human body.
What is NREM sleep?
Our bodies wear out hormones, neurotransmitters, and energy which is why this theory suggests sleep restores, repairs and reenergize to support growth (muscle and brain tissue) especially during NREM-3
What is restoration theory?
Sigmund Freud proposed dreams are the road to our unconscious mind. Filled with these 2 contents:
1. What the dream is
2. That which we cannot or will not face in our conscious waking life (meaning behind the dreams)
What are manifest content and latent content?
The brain waves released during NREM stage 2 sleep. Heart rate as well as breathing slow down. Sleep spindles (brief and rapid bursts of brain activity) and K-complexes are associated with these brain waves.
What are theta waves?
Cessation of breathing while sleeping, snoring, never feeling rested or restored even after a full night sleep are characteristic of this sleep disorder.
What is sleep apnea?
Stage of sleep where vivid dreams occur. Believed to restore our mind (cognition, memory, decision-making).
What is REM sleep?
This theory suggests sleep and dreams help the brain integrate and process memories from short-term to long-term, particularly during REM sleep stage 4.
What is memory consolidation theory of sleep?
Brain waves (.5 - 4Hz) released during NREM stage 3 sleep; deepest stage of sleep. In adults, the presence of these brain waves when awake can indicate brain damage, ADHD, or other neurological disorders.
What are delta waves?
Uncontrollable "sleep attacks", constant drowsiness, and muscle paralysis (cataplexy) are characteristic of this sleep disorder. Caused primarily by genetic factors.
What is Narcolepsy?
Essential part of the sleep for the mind.
What is REM sleep?
This theory suggests that dreams allows the brain to make sense and organize random events, images, and interactions with people.
What is activation-synthesis model?
We sleep in cycles. Each cycle has 4 stages which last approximately this amount of time.
What is 90-120 minutes? What is 1 & 1/2 to 2 hours?
These are the 3 different types of apnea. soft tissues of the throat relax, brain fails to send correct signals to breathing muscles, and a combination of the two.
What are obstructive(OSA), central (CSA), and complex apnea?
Stage of sleep in which physical restoration of the body occurs repairing muscle tissue and strengthens immune system. Deepest stage of sleep, difficult to awake
What is NREM stage 3?
Sleep lab research measures any of these 5 things.
What is Muscle tone, Heart rate, Brain waves, Oxygen levels, and temperature?
