Q

depressants

A

inhibit central neural system functions
- ex: alcohol
- GABA agonist deactivates glutamate (drug mimics GABA and causes a slowing of the CNS because glutamate usually speeds up CNS but drug agonist would deactivate that)
- activates opiod receptors that release endorphins

Q

Stimulants

A
  • speed up CNS
  • dopamine, and serotonin inhibitor
  • block reuptake increases affect of nt that is being blocked, so serotonin increases
  • amps people up and has positive effects
    ex: cocaine

16
Q

narcotics

A
  • slow/stop breathing (brain stem)
  • can inhibit pain signals (in spinal cord because it has opioid receptors)
  • used medically for pain
17
Q

Opiates vs opioids

A

opiates are natural (morphine, heroin and codeine)
and opioids are natural and synthetic (fentanyl, methadone)

18
Q

circadian rhythm

A

cyclical changes in our biological processes that occur roughly in a 24 hour basis
- has relationship with light

19
Q

suprachiasmatic nucleus

A

releases melatonin

20
Q

pathway linking light to melatonin

A

light entering eye that is detected by retinohypothalamic tract, then it reaches suprachiasmatic nucleus and the amount of light that enters determines the release of melatonin

21
Q

disruptions to circadian rhythm

A

-daytime: more light, less melatonin
- night time
- night shift: low natural light
- jet lag
- daylight saving time: shifts when we see light

22
Q

awake

A

beta waves (14-30Hz)

23
Q

calm wakefulness

A

alpha waves (8-12Hz)

24
Q

stage 1

A

theta waves (4-7 Hz)

25
Q

myoclonic

A

feeling of falling or rapid movement that occurs in stage 1 of sleep

26
Q

stage 2

A
  • k complex: organizes memories, brain inhibition and info processing
  • sleep spindles: consolidates/stabilizes memory
  • 65% of sleep is in stage 2
27
Q

stage 3 and 4

A

delta waves (2-4 Hz)
- deep sleep
- physical healing and growth

28
Q

rapid eye movement (REM)

A
  • paradoxical and short
    fast brain activty but still asleep
  • beta waves (14-30)
  • 10-30 minutes
  • eyes moving rapidly
  • most likely to have weird dreams in rem
29
Q

full sleep cycle

A
  • full sleep cycle is about 90 minutes
  • spend less time in stages 3 and 4 in later hours of sleep
  • length of time in rem increases as time goes on
30
Q

activation-synthesis theory

A
  • pons: activation
  • spontaneous activation across whole brain at night
  • pons sends signals for things that are not really there
  • cerebral cortex: synthesis
  • inteprets/synthesizes activity to try to make sense of it all
31
Q

hypnosis

A

hightened suggestibility
- more likely to do what others say
- mesmer was the first user
