Study Notes
States of Consciousness
- Consciousness is awareness of internal and external stimuli
- Biological rhythms: Internal patterns of biological activity, like the menstrual cycle, which reoccur
- Circadian rhythm: A 24-hour biological cycle, linked to the light-dark cycle (sleep-wake cycle, heart rate, blood pressure, blood sugar, body temperature)
- Homeostasis: Maintaining balance within a biological system
- Suprachiasmatic Nucleus (SCN): Brain's internal clock, located in the hypothalamus; receives light information from the retina to synchronize with the outside world
Disruptions of Normal Sleep
- Jet lag: Symptoms from mismatch of internal circadian rhythms and environment
- Rotating shift work: Work schedules changing from early to late.
- Sleep debt: Insufficient chronic sleep
Sleep
- Sleep rebound: Shorter time to fall asleep after sleep deprivation
- Evolutionary psychology: Studies how universal patterns of behavior and cognitive processes have evolved over time
- Stages of sleep: NREM and REM
- Stage 1: Transitional between wakefulness and sleep
- Stage 2: Deeper relaxation (Theta waves, sleep spindles, K-complexes)
- Stages 3 & 4 (NREM): Deep/slow-wave sleep (Delta waves), crucial for physical recovery, learning, and memory.
- REM: Similar brain waves to wakefulness, characterized by rapid eye movements, muscle paralysis, and dreaming
Sleep Problems and Disorders
- Insomnia: Difficulty falling/staying asleep, or waking up too early
- How to Diagnose Insomnia: Symptoms must be present for at least 3 nights a week for at least a month.
- Causes of Insomnia: Stress, irregular sleep schedule, diet, medications, anxiety or depression, medical conditions, nicotine and caffeine, alcohol.
- How to Prevent Insomnia: Consistent bedtime and wake times, regular exercise, medication review, avoiding caffeine and alcohol/nicotine before bed time.
- Parasomnias: Disruptive sleep disorders during arousals from REM or NREM sleep, including:
- REM parasomnias: Acting out dreams (nightmares, sleep paralysis, REM sleep behavior disorder)
- Non-REM parasomnias: Arousal disorders (sleep terrors/night terrors, sleepwalking, confusional arousals).
- Sleep Apnea: Breathing stops and starts during sleep
- Obstructive Sleep Apnea: Airway blockage
- Central Sleep Apnea: Brain's signals to control breathing are disrupted
- Sudden Infant Death Syndrome (SIDS): Infant stops breathing during sleep, and dies, often unexplained
Altering States of Consciousness
- Narcolepsy: Excessive sleepiness
- Caffeine: Stimulant, increased alertness and arousal
- Nicotine: Highly addictive, increased heart disease risk, stroke
- Opioids: Analgesic (pain-relieving) properties; includes heroin, morphine, methadone, codeine
- Hallucinogens: Altered sensory and perceptual experiences
- Medical Marijuana: Legal in some states for limited quantities, with implications for recreational use.
- Hypnosis: Extreme self-focus, minimal attention to external stimuli.
