How does our sleep cycle work? O Do Now: have you ever taken a nap and felt more rested than you did when you slept a full night? Why do you think this is?

Circadian Rhythm O During a 24-hour period, our metabolic and thought processes follow a certain pattern. O Part of this rhythm is our sleep cycle. O Researchers use EEG to record how active our brains are during sleep and identify and describe the different stages of sleep. How does our sleep cycle work?

The Sleep Cycle How does our sleep cycle work?

The Sleep Cycle How does our sleep cycle work?

The Sleep Cycle O Sleep onset: the period when you are falling asleep. O REM: Rapid Eye Movement: this stage is also called paradoxical sleep. In this stage, our brain waves are as active as when awake, but we are sleeping. O Dreams usually occur in REM sleep. O REM sleep deprivation interferes with our memory. O The more stress during the day, the longer our REM sleep will last. O What does this imply about REM sleep? How does our sleep cycle work?

Summary O Babies spend more time in REM sleep. Explain why this is. How does our sleep cycle work?

How do sleep disorders impact an individual? O Do Now: think of a night you slept very little. What affect did the lack of sleep have on you the following day? Throughout this lesson, you will see questions in orange. On a separate sheet of paper, answer these questions.

What is a sleep disorder? O Sleep disorders are identifiable and diagnosable. O Insomnia O Sleep apnea O Narcolepsy O Night terrors O Somnambulism O Throughout this lesson, there will be questions in orange. You are to answer these questions on a separate sheet of paper to be collected at the end of the period. How do sleep disorders impact an individual?

Insomnia O Insomnia is the most common sleep disorder. O A person with insomnia has a difficult time falling asleep or staying asleep. O This disorder is persistent, not sporadic. O 1. Based on what you know about the sleep cycle, how does this disorder impact an individual? How do sleep disorders impact an individual?

How is insomnia treated? O Insomnia is treated by having the patient adjust their daily habits. O Reduce the intake of caffeine and other stimulants. O Exercise patterns may be adjusted (exercise in the morning, not right before bed time). O Maintaining a consistent sleep pattern. O 2. How might maintaining a consistent sleep pattern help? O As a last resort, sleeping pills may be prescribed. How do sleep disorders impact an individual?

Sleep Apnea O Sleep apnea is also fairly common. O Sleep apnea is considered by some researchers more dangerous that insomnia. O Apnea causes a person to stop breathing for short periods of time during sleep. O The body causes the individual to wake up, gasp for air, and then fall back asleep. O 3. According to what you know about the sleep cycle, how may this impact an individual? How do sleep disorders impact an individual?

Narcolepsy O Narcolepsy is rare. O Individuals with narcolepsy suffer from periods of intense sleepiness and may fall asleep at unpredictable and inappropriate times. O Narcolepsy is treated with medication and changing sleeping patterns. O Changing sleeping patterns usually involve periodic naps throughout the day. How do sleep disorders impact an individual?

Night Terrors Night Terrors and Somnambulism O Night terrors usually affect children. O Most individuals do not remember the episode when they wake up. O The exact cause of night terrors is unknown, but researchers believe they are most likely related to somnambulism. O Somnambulism is sleep walking.

Do our dreams have meaning? O Do Now: pick one dream from your dream journal and explain the meaning you think it has.

The meaning of dreams O Today we will discuss theories of the meaning of dreams. O These theories are hard to validate, since it is difficult to access one’s dreams. O Your dream journal may hold some insight to the meaning of your own dreams, but proving these meanings in near impossible. Do our dreams have meaning?

Sigmund Freud O Freud found dreams to be an important tool in his therapy (psychoanalysis). O Freud believed that dreams were a window into our unconscious mind. O Freud emphasized two levels of dream content: O Manifest Content O Latent Content Do our dreams have meaning?

Manifest Content O Manifest content is the literal content of our dreams. Do our dreams have meaning?

Latent Content O Latent content is the meaning of the manifest content. O Freud’s therapy focused on the latent content of dreams. O Protected Sleep: Freud believed our ego was protecting us from our real desires, and this is why they manifested themselves in the form of symbols in our dreams. O Our superego is what causes us to forget our dreams. O Just as with Freud’s theory of the conscious mind, we can not prove this theory, so many question it validity. Do our dreams have meaning?

Activation-Synthesis Theory O The activation-synthesis theory examines the biological process of sleep. O Brain imaging proves our brain is very active during the REM stage of sleep. O This theory states that our dreams are just the brain’s interpretation of the physiological activity of REM sleep. O Dreams may be a product of the literary part of our mind. O According to this theory, do our dreams have meaning? Do our dreams have meaning?

Information-Processing Theory O The information-processing theory is somewhere in the middle of Freud’s theory and the activation-synthesis theory. O This theory points out that the level of stress during the day and the frequency and intensity of dreams at night are related. O Perhaps this is how the brain is coping with stress by forcing the individual into REM sleep. Do our dreams have meaning?

Summary O What theory do you agree with most and why? O Use examples from your dream journal where applicable. Do our dreams have meaning?

How do drugs affect our consciousness? O Do Now: why do you think people use recreational drugs?

Psychoactive Drugs O Psychoactive drugs are chemicals that change the chemistry of the brain and induce an altered state of consciousness. O The blood-brain barrier is the protective layer of the blood vessels of the brain. It’s purpose is to protect the brain from chemicals. O The molecules of psychoactive drugs are small enough to pass through the blood- brain barrier. How do drugs affect our consciousness?

How do Psychoactive Drugs work? O Psychoactive drugs work by either mimicking or blocking normal neurotransmission. O Agonists: mimic neurotransmitters. O Antagonists: block neurotransmitters. How do drugs affect our consciousness?

Tolerance and Withdrawal O Tolerance is when an individual becomes used to the effects of a psychoactive drug. O Why is this dangerous? O Withdrawal is characterized by the reactions an individual has when they stop using a psychoactive drug. How do drugs affect our consciousness?

What are the 4 Categories of Psychoactive Drugs? O Stimulants O Depressants O Hallucinogens O Opiates How do drugs affect our consciousness?

Stimulants O Examples include: caffeine, cocaine, amphetamines and nicotine. O Stimulants speed up body processes. O This increase is usually accompanied by a feeling of euphoria. O Side effects include: disturbed sleep, reduced appetite, increased anxiety, and heart problems. How do drugs affect our consciousness?

Caffeine’s Effect on the Body How do drugs affect our consciousness?

Depressants O Examples include: alcohol, barbiturates (sleeping pills), and anxiolytics (like Valium). O Depressants slow down body processes and reactions and impair our judgment. How do drugs affect our consciousness?

Hallucinogens O Also called psychedelics O Examples include LSD, peyote, psilocybin mushrooms and marijuana. O Hallucinogens cause changes in perceptions of reality, including sensory hallucinations, loss of identity and vivid fantasies. O Effects are not predictable. O Hallucinogens stay in an individuals systems for extended periods of time and when a new dose is taken, it may cause greater effects. O This is called reverse tolerance because even though the second dose may be less, it produces greater effects. How do drugs affect our consciousness?

LSD and the Brain How do drugs affect our consciousness?

Opiates O Examples include: morphine, heroin, methadone and codeine. O Opiates act as agonists for endorphins, so they are powerful painkillers and mood elevators. O Opiates cause drowsiness and euphoria. O Opiates are the most physically addictive drugs because they rapidly change brain chemistry. How do drugs affect our consciousness?

Group Project O You will work in groups to create a presentation in which you will discuss several drugs within your groups category. O You will discuss whether the drug is an agonist or antagonist, the parts of the brain in which the drug can damage/effect, the neurotransmitters affected and any other pertinent information which will help you and your peers be successful on the AP Psychology exam. O Be sure to reference the 425 Terms handout! How do drugs affect our consciousness?
