What is Sleep?

processing and storing memories and learning.

Sleep Deprivation

A high school student in Sand Diego, Randy Gardner, set a world record for sleep deprivation in 1964. He went for 264.4 hours (11 days) without sleep.

Eventually, he became psychotic. He had problems with concentration and short-term memory, paranoia, and hallucinations. At one point, he believed he was the running back for the San Diego Chargers.

Sleep

• EEG records are used to study the sleep process. The sleep wave patterns are characterized by their frequencies (cycles per second) –beta waves, 14 to 30 cycles per second – alpha waves, 8 to 13 cycles per second – theta waves, 4 to 7 cycles per second –delta waves, under 4 cycles per second

The stages of sleep

Stage 1 sleep–Relaxed wakefulness–Alpha waves– Less desynchronised brain activity– Easy to awaken• Many people may experience a sensation of

falling during stage 1, this may cause a sudden muscle contraction. This jerk is called a hypnic myoclonia

Page 24: Sleep Unit 2 Body and Mind. Do Now Fill out your sleep logs!

The stages of sleep• Stage 2 sleep– Deep, slow brain waves, Delta Waves start. This is

the transitional period between light sleep & a very deep

– Heart & breathing rate continue to fall– Difficult to awaken.

The stages of sleep

• REM sleep after about 90 minutes EEG shows SHIFT into fast, desynchronised brain activity (rapid eye movement) – Eyes may be moving– Dreams happen in REM– Temporary sleep paralysis (to keep you from acting out

your dreams)– EEGS show REM brain waves are similar to those of

wakefulness

REM sleep

The stages of sleep

• Once REM sleep is over, we usually return to stage 2 sleep.

• Sleep cycles through these stages four or five times a night.

• Each REM cycle becomes longer, so we actually dream more toward morning.

Why do we dream?

• According to the Cognitive Problem Solving Model dreams are a type of thinking. – We have no constraints on our thoughts during

sleep and so we are free to work out problems while we are sleeping

Page 30: Sleep Unit 2 Body and Mind. Do Now Fill out your sleep logs!

Why do we dream?• According to the Activation Synthesis

Model, dreams are the byproducts of surges of neural activity in the brain.

Our brains receive random neural impulses and tries to make sense of them in random dreams.

Page 31: Sleep Unit 2 Body and Mind. Do Now Fill out your sleep logs!

Why do we dream?• According to Freud and the Psychoanalytic

Theory, our dreams are a result of our subconscious and the information it holds.

What we cannot process consciously, or speak about in public, we dream about.

The ID drives our dreams!

Why do we dream?Other Theories of Dreams:

• Our brains trying to interpret external stimuli during sleep– For example, the sound of the radio may be

incorporated into the content of a dream

• Dreams serve to ‘clean up’ clutter from the mind, much like clean-up operations in a computer, our brains de-frag

• Our dreams function as a form of psychotherapy. In dreams we are able to make connections between different thoughts & emotions in a safe environment .
