| 8164009353 | consciousness | our awareness of ourselves and our environment, a part of the mind from which we can potentially retrieve a fact, an idea, an emotion, or a memory and combine it with critical thinking. | 0 | |
| 8165355098 | 3 main functions of conciousness | restricts our attention (selective attention); where sensation combines with memory, emotions, and motives; allows us to create a mental model of the world that we can manipulate (only HUMANS can do this!) | 1 | |
| 8164184963 | states of conciousness | spontaneous states: daydreaming, drowsiness, dreaming physiologically enduced states: hallucinations, orgasms, food or oxygen starvation psychologically enduced states: sensory deprivation, hypnosis, meditation | 2 | |
| 8164011682 | chronobiology | a field of biology that examines organisms and their adaptation to solar- and lunar-related rhythms. These cycles are known as biological rhythms. | 3 | |

| 8164013867 | cortisol | hormone that keeps you awake, may be associated with insomnia | 5 | |
| 8164017812 | melatonin | hormone that induces sleep, controlled by the pineal gland, connected to the wake-sleep cycles that builds up while we sleep. | 6 | |
| 8164019930 | circadian rhythms | the "body clock", 24-hour cycle that rules us all. This internal body clock is affected by external forces, such as sun rise and time zones. Ex: as we approach night time, our body temperatures begin to drop. | 7 | |

| 8164061809 | sleep apnea | sleep disorder where a person stops breathing during their sleep (stop breathing 300-500 times a night). Wake up momentarily, gasps for air, then falls back asleep. Common in overweight males, can be helped by a CPAP macheine. | 34 | |

| 8164082609 | hypnosis | a social interaction in which one person (subject) responds to another person's (the hypnotist) suggestions that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur, can be therapeutic and can alleviate pain by blocking our attention to painful stimuli (does not block sensory input to pain) | 46 | |
| 8164264482 | limits to hypnosis | hypnosis doesn't enhance the ability to recall forgotten events, may even evoke false memories; a hypnotist can't force people to act against their will, they may perform unlikely acts, but not any more than a not-hypnotized person. | 47 | |

| 8164376294 | social influence theory | belief that hypnosis is not an altered state of concious, but rather a power of social influence that causes subjects to behave like "good hypnotic subjects" the more they like and trust a hypnotist, and the more they believe they are hypnotised. | 51 | |
| 8164414873 | divided consciousness theory | belief that hypnosis is more than a person playing the role of a "good subject" and believe that hypnosis evokes a separate state of consciousness (dissociation) Ex: ice water experiment | 52 | |
| 8164091656 | dissociation | a split between levels of consciousness which allows some thoughts and behaviors to occur simultaneously as others. Used in hypnosis to alleviate pain by separating the physical stimulus of pain from the emotional suffering that defines our experience of pain | 53 | |
| 8164094496 | psychoactive drug | a chemical substance that alters perceptions and moods, small enough to pass through the blood-brain barrier, (Alcohol, Marijuana, and Cocaine, etc.) | 54 | |

| 8180193457 | amphetamines | Drugs that stimulate neural activity, causing sped-up body functions and associated energy and mood changes, increases the levels of dopamine and norepinephrine, results in short-term energy and euphoria, but eventually reduces baseline dopamine level, leaving user permanently depressed, Ex: Cocaine | 63 | |
| 8164105887 | hallucinogens | Psychedelic (mind-manifesting) drugs that distort perceptions and evoke sensory images in the absence of sensory input, Ex: LSD | 64 | |
| 8164109302 | barbiturates | Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment (tranquilizers), Nembutal, Seconal, and Amytal are sometimes prescribed for sleep or to reduce anxiety. | 65 | |
| 8164109303 | opiates | Opium and its derivatives (morphine and heroin) depress neural activity, temporarily lessening pain and anxiety. | 66 | |
| 8164114897 | ecstasy | (also called MDMA) is a synthetic stimulant and mild hallucinogen, short-term health risks and long-term effects that include: high blood pressure, harm to serotonin-producing neurons, death, and it affects mood and cognition. | 67 | |

| 8164117525 | THC | the major ingredient in marijuana; triggers a variety of effects including mild hallucinations. | 69 | |
| 8164117526 | cocaine | a powerful and addictive stimulant, derived from the coca plant, producing temporarily increased alertness and euphoria, traps dopamine in synaptic gap and dopamine particles bind to receptor sites over and over and overstimulate the cell. | 70 | |
| 8164120832 | methamphetamine | a powerfully addictive drug that stimulates the CNS with speeded-up body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels, works by entering the dopamine vesicles and pushing dopamine neurotransmitters out of the cell and into the synapse where they can connect to the receptor sites | 71 | |
| 8164124908 | near-death experience | an altered state of consciousness reported after almost dying (such as by cardiac arrest) often similar to drug-induced hallucinations which might be caused by the brain being under stress such as oxygen deprivation. | 72 | |
| 8164138197 | Allan Hobson & Robert McCarley | psychiatrists and neurophysiologists at Harvard's medical school who believed that dreams are nothing more than your attempt to interpret random electrical impulses produced by your brain in REM sleep. | 73 | |
| 8164143587 | Eugene Aserinsky | discovered REM sleep, and found that dreams occur in REM sleep | 74 | |
| 8164145512 | Nathaniel Kleitman | 75 | ||
| 8164148586 | William Dement | studied what would happen if a person was deprived of dreaming and REM sleep. He discovered that as a person is deprived of REM sleep, they try to spend more and more time in REM which is known as REM rebound, this shows the importance of REM sleep and dreaming. | 76 | |
| 8164148587 | Sigmund Freud | theorized that dreams are the expression of un-conscious wishes that we are unable to have while awake. He also believed that dreams have a manifest content (surface meaning) and a latent content (true, underlying meaning) | 77 | |
| 8164152273 | Ernest Hilgard | believed hypnosis involves not only social influence but also a special dual processing state of dissociation (Divided-conciousness theory). He viewed hypnotic dissociation as a vivid form of everyday mind splits (dual processing) | 78 | |
| 8164152274 | Martin Orne & Frederick Evans | showed that both hypnotized and unhypnotized subjects who were told to throw acid in a researcher's face followed through on the request, which shows that hypnotized people don't do anything that unhypnotized people can't also be convinced to do. | 79 |
