7
Circadian Cycles
  • Adaptation to 24 hour solar cycle of light and
    dark
  • Info obtained by neurons from the eye
  • Neurotransmitters released to control
    temperature, metabolism, blood pressure,
    hormones, hunger

Functions of Dreams
  • Unconscious wishes (Freud)
  • Motives guiding behavior (ones you arent aware
    of)
  • Free of moral controls
  • Obvious/manifest content
  • Saying goodbye to someone
  • Hidden/latent content
  • Killing that someone

10
Functions of Dreams
  • Information processing
  • Reprocess info obtained during the day
  • Scan new info to decide how to incorporate with
    existing memories
  • Decide what information to store and toss
  • Where info should be stored in the brain
  • Strengthens memories
  • Cleans neural pathways
  • Emotional processing
  • Work through problems in dreams
  • Healthy part of processing difficult emotions
  • Resulting from divorce, grief, crisis

11
Sleep
  • Sleep losing awareness and failing to respond to
    something that you would if awake
  • Restorative function for mind and body
  • Boosts immune system
  • Better problem solving abilities
  • Conserve/restore energy

12
Sleep Cycles - NREM
  • Twilight Irregular, low-voltage brain waves
  • Relaxed wakefulness like lying on a beach
  • Falling sensation waking you up
  • Stage 1 Brain waves are tight and very low
    similar to when you are excited but rest of body
    is in a state of rest
  • Lasts only a few moments
  • Might not know you were asleep if awaken

13
Sleep Cycles - NREM
  • Stage 23 Continuing to fall into a deeper state
    of rest
  • Harder to awaken
  • Heart rate, blood pressure, temperature continue
    to drop
  • Stage 3 Delta waves begin to appear
  • Stage 4 Delta waves (very slow)
  • Lowest point of rest
  • 15-20 min segments

14
Sleep Cycles
  • At this point, you begin to ascend (from stage 4
    to 3, 2, and 1)
  • Takes about 40 minutes
  • REM resemble awake signs but muscles most
    relaxed
  • Hard to awaken in this state
  • Eyes move rapidly
  • Voluntary movement of muscles are paralyzed
  • Many dreams occur during this stage

15
Sleep Cycles
  • Stage 1 to 4 and then back again
  • First REM occurs when you first return to Stage 1
  • First REM is about 10 minutes
  • Entire sleep cycle (Stage 1 to 4 and then back to
    Stage 1-REM) takes about 90 minutes
  • 4-5 full sleep cycles per night
  • Early sleep, more time in Stages 34
  • Shifts to more time in Stage 1-REM with each
    cycle
  • REM sleep time decreases with age

16
How Much Sleep?
  • Infants 13-16 hours in first year
  • 50 time is REM
  • Adult 6-8 hours
  • 1-2 hours is REM (20-25)
  • Elderly 4-6 hours

  • Is it common for you to fall asleep after large
    meals or while relaxing after dinner?

    during boring lectures, tedious activities, or in
