Unconsciousness: we are unaware of Hypnosis: a social interaction in which one person (the subject) response to another person’s (the hypnotist) suggestions that certain perceptions, feeling, thoughts or behaviors will spontaneously occur. BBC Supernatural Science Open to Suggestion 51 minutes https://www.youtube.com/watch?v=C5AhnLsogpU Frequently Asked Questions about Hypnosis Can anyone experience hypnosis? We are all open to suggestion. Can hypnosis enhance recall of forgotten events? No Can hypnosis force people to act against their will? It can’t make you do something you don’t want to Can hypnosis be therapeutic? Post hypnotic suggestions help alleviate headaches, asthma and stress related skin disorders. Can hypnosis relieve pain? Yes Circadian Rhythm is our 24 hour biological clock. Our body temperature and awareness changes throughout the day. Annual Cycles: seasonal variations (bears hibernation, seasonal affective disorder) 28 day cycles: menstrual cycle. 24 hour cycle: our circadian rhythm or 25 hours? 90 minute cycle: sleep cycles. Pick number 13 http://www.learner.org/resources/series142.ht ml?pop=yes&pid=1581 Many of our behaviors display rhythmic variation. Circadian rhythms One cycle lasts about 24 hours (e.g. sleep-waking cycle). Light is an external cue that can set the circadian rhythm. Some circadian rhythms are endogenous suggesting the existence of an internal (biological) clock. Environmental cues When darkness falls, the eyes indirectly inform the pineal gland (responsible for the body’s natural cycles and registering light and darkness). The pineal gland secretes the hormone melatonin in response to darkness, making us drowsy. This affects the brain cells which produce Serotonin, a sleep-related transmitter substance. The serotonin is concentrated in the Raphe Nuclei (near the pons), which secrete a substance that acts to induce light sleep. http://educationportal.com/academy/lesson/pineal-gland-functionsmelatonin-circadian-rhythm.html#lesson 1. Sleep Protects 2. 2. Sleep helps us recuperate. 3. Sleep helps restore and rebuild our fading memories of the day’s experiences. 4. Sleep feeds creative thinking. 5. Sleep supports growth. 90 minute sleep cycles. Found this out because Eugene needed to test an EEG out that he repaired that day so he put it on his son Armond. Watched the machine go wild, Discovered REM sleep (rapid eye movement) Sleep spindles: bursts of rapid, rhythmic brain-wave activity. Your brain’s motor cortex is active during REM sleep but your brainstem blocks its messages. This leaves your muscles relaxed, so much so that, except for an occasional finger, toe, or facial twitch, you are essentially paralyzed. Sometimes this last even when you wake up producing sleep paralysis. Alpha waves: slow brain waves of a relaxed, awake state. Think about brainwaves as the gears on a bicycle. When you get into a stressful situation, such as going up a big hill, you need to be able to switch to a smaller gear so that you are able to pedal at a steady rate. However, since you are in a smaller gear each foot push doesn’t get you quite as far as other gears. So the first few gears on a bike would be like Beta brainwaves, they move fast and are excellent to get you through stressful situations. As you move onto flat terrain you want to switch to a mid-level gear that allows you to pedal at a steady speed that is not too much work on your thighs. These gears are like Alpha waves. But as the grade starts to turn to slightly downhill, you can easily slip into a higher gear and still not work that hard. That slightly higher gear, like Theta waves, the chain on the bike makes fewer revolutions but continues to turn the wheels at the same rate. Finally, when you head down a huge hill, you shift into the highest gear to be able to keep moving your feet or if you’re like me, you just quit pedaling and let gravity take you away. Delta brainwaves equate to this gear. When you are in deep sleep, your brain is only slightly or not at all active, thus not in full control just like when your zooming down a big hill. Stage 1: Alpha and theta waves produced in light sleep Hypnic Jerk: Reflex muscle twitch throughout body that may occur Stage 2: Deeper sleep; sleep spindles (distinctive brainwave activity of half second or longer) Stage 3: Deeper sleep; Delta waves appear (very large and slow), breathing regular, BP falls. Stage 4: Deepest level of normal sleep; almost purely Delta waves (50%) – less blood flow to the brain REM: Rapid Eye Movement This is a very active stage of sleep. Composes 20-25 % of a normal nights sleep. Breathing, heart rate and brain wave activity quicken. Vivid Dreams can occur. From REM, you go back to Stage 2 How does sleep loss affect us, and what are the major sleep disorders? Sleep takes up 1/3 of our lives, 25 years on average. Most adults will sleep at least 9 hours. How do you feel when you don’t get enough sleep? Drained, tired and it can make you fatter. Deprivation increases ghrelin, a hunger-arousing hormone and decreases its hunger-suppressing partner, leptin., immunity, reaction times : Occurs in NREM sleep during Stages 3 and 4 Total panic and hallucinations may occur (mostly children) Seldom recall anything. Interrupted breathing during sleep; cause of very loud snoring persistent problems in falling or staying asleep. Sudden attacks of uncontrollable sleep attacks. Psychoanalytic: Dreams represent disguised symbols of repressed desires and anxieties. Manifest versus latent content Biological: Dreams represent random activation of brain cells during sleep. To develop and preserve neural pathways. Perhaps providing the brain with periodic stimulation. OR Dreams are the brain’s attempt to make sense of random neural activity. Cognitive: ( Information-processing)Dreams help to sift and sort the events of the day. © 2004 John Wiley & Sons, Inc.

Causes precancerous changes in lung cells. Can suppress immune system, perhaps increasing risk of disease. Activity levels in the cerebellum are lower than normal in pot users. Pot may damage some of the brain’s memory centers.
