2 States of Consciousness Levels of Consciousness Sleep and Dreaming Sleep Disorders Hypnosis Meditation

3 What is the difference between Conscious, Unconscious and Subconscious ? Many states of consciousness Daydreaming, dozing, deep sleep, awareness – all different aspects of consciousness Unconscious – physically unable to awaken Subconscious – inner thoughts and feelings you are not totally aware of

4 What is Unconsciousness? Physical loss of responsiveness to the environment Causes: disease, trauma, anesthesia Consciousness can be altered by: sleep, hypnosis, meditation and drugs Physical loss of responsiveness to the environment Causes: disease, trauma, anesthesia Consciousness can be altered by: sleep, hypnosis, meditation and drugs

5 What is a Coma? A Coma is a profound state of unconsciousness. A comatose person cannot be awakened, fails to respond normally to pain, light or sound, does not have sleep/wake cycles and does not take voluntary actions. The underlying cause of coma is bilateral damage to the Reticular Activating System in the midbrain which is important in regulating sleep Coma can result from: stroke, trauma, intoxication, hypoxia or induced as a form of preserving higher brain function during healing process

6 Glasgow Coma Scale Generally, brain injury is classified as: Severe, with GCS ≤ 8 Moderate, GCS 9 - 12 Minor, GCS ≥ 13.

7 What exactly happens during sleep? Consciousne ss Awareness Responsiven ess Physiological awakening Sleep is a complex combination of states of consciousness, each with its own level Sleep is a heightened energy state, accentuating the growth and rejuvenation of the immune, nervous, skeletal and muscular systems. It is observed in all mammals, all birds, and many reptiles, amphibians, and fish

8 How does our body know when to sleep? Regulates temperature, blood pressure, pulse, blood sugar, throughout the day Your free running biological clock is 25 hours long Hypothalamus Your natural biological clock – during light/dark turns into 24 Cycles all day and night Circadian rhythms RAS (Reticular Activating System) – changes in wakefulness, arousal, attention, mood, energy level Night shift work, jetlag disrupt circadian rhythms Reticular Formation

10 First 4 Sleep Stages – NREM (Non Rem) Twilight Sleep: sensation of falling, peaceful, hazy, Melatonin triggered Fail to immediately respond to outside stimuli Stage 1: Sudden twitches and hynic jerks (myoclonus reactions) Lose most conscious awareness of the external environment. Stage 2: sleep spindles (bursts), lose all awareness of environment Stage 3: Slow wave sleep – sleep walking, bedwetting can be issues Stage 4: Heart beat drops, BP low, H.G.H secreted

11 You go backwards! Passing back through stages 3,2, and 1 – but THEN something else happens…. You begin REM Sleep (Rapid Eye Movement) Every 90 minutes after falling asleep your eyes jerk back and forth in various directions Your limbs become paralyzed B.P., heart rate increases What happens after stages 1-4? Through the night you cycle through stages with REM increasing in length –then decreasing towards awakening.

12 REM SLEEP

13 Sleep Deprivation makes you drowsy Unable to concentrate, impairs memory and concentration Impacts Immune System Sleep time seems to decrease from about 16 to 18 hours for a newborn to 7 or 8 for an adult What is Sleep Deprivation

14 What are some Sleep Disorders Insomnia: inability to fall/maintain sleep Narcolepsy : a sleep disorder that causes excessive sleepiness and frequent daytime sleep attacks Cataplexy: rare sleep disorder that causes immediate REM sleep when excited or emotional Restless Leg Syndrome is a disorder in which there is an urge or need to move the legs to stop unpleasant sensation Insomnia: inability to fall/maintain sleep Narcolepsy : a sleep disorder that causes excessive sleepiness and frequent daytime sleep attacks Cataplexy: rare sleep disorder that causes immediate REM sleep when excited or emotional Restless Leg Syndrome is a disorder in which there is an urge or need to move the legs to stop unpleasant sensation Sleep apnea is a condition in which a person has episodes of blocked breathing during sleep

15 Living with Cataplexy

16 When do you have nightmares? Occur during REM Sleep – most dreams occur during this phase Dreams remembered from other stages are less emotional and sensible Lucid Dreaming: training to be aware of and direct one’s dreams to help cure people of nightmares. Incubus: Night Terrors – wake during REM – happens to young children often after disruption of sleep cycle, (holidays, guests, vacations, etc.) Occur during REM Sleep – most dreams occur during this phase Dreams remembered from other stages are less emotional and sensible Lucid Dreaming: training to be aware of and direct one’s dreams to help cure people of nightmares.

20 What do dreams mean? Some popular theories Freud: “Royal road to the unconscious” “Manifest Content” – remembered parts “Latent Content” - underlying meaning McCarley and Hobson: Activation Synthesis Theory: during dreams the pons generates bursts of action potentials to the brain Freud: “Royal road to the unconscious” “Manifest Content” – remembered parts “Latent Content” - underlying meaning McCarley and Hobson: Activation Synthesis Theory: during dreams the pons generates bursts of action potentials to the brain You try to create a story line out of it (synthesize) Origins of dreams are either psychological or physiological depending on what theory you follow Most of your dreams happen between 4 and 7 am.

22 What is your most memorable dream? DO NOW

23 What do I need to know about sleep? There are different phases of sleep from just being drowsy to awakening 4 phases in non rem (NREM) and 4 in REM (rapid eye movement) REM is a very active period in your brain, but you are physically paralyzed. Teens need 9 plus hours a night for optimum health – but often don’t get it Adults need less as they age Dreams – most occur between 4-7 am Theories: repressed desires, spindle bursts in brain, reorganization of thoughts Disorders: Isomnia, Narcolepsy, Night Terrors, Apnea, Restless Leg Syndrome.
