Flashcards in ch.3 Deck (50):
1

neruon

information processing in the brain

2

neurons (3):

(dendrite, cell body, axon). Protein synthesis, energy production, metabolism

3

cell body (function)

keeps cell alive, (coordinates information processing tasks.)

4

multiple sclerosis caused by:

myelin sheath deteriorates

5

sensory neurons:

convey info from spinal cord to brain. (sight, touch, taste, hearing, smell)

6

motor neurons:

carry signals from spinal cord to muscles to produce movement.

7

interneurons (3 types):

neurons that connect all neurons (motor, sensory, interneurons)

8

resting potential

difference in electric charge between the inside and outside of neurons cell membrane.

9

synaptic transimission

underlies thoughts, emotions and behavior

10

Acetylcholine

voluntary motor control

11

Dopamine

feel good, regulates motor behaviour, pleasure, motivation

12

Glutamate

info transmission throughout the brain

13

Norepinephrine

influences mood and arousal

14

serotnin

sleep/wakefulness, eating and aggressive behaviour

15

endorphins

pain pathways and emotion centers

16

agonists

increase action of neurotransmitter

17

antagonists

block the neurotransmitter

18

sympathetic nervous system

prepares body for action in threatening situations (ejaculation)

19

parasympathetic nervous system

helps body return to normal resting state (erection)

20

spinal cord/ brain

moving your muscles, walk, responding to pain, breathing

21

hindbrain

(medulla, cerebellum, pons) info coming into and out of spinal cord

22

medulla

heart rate, circulation, and respiration

23

reticular formation

sleep, wakefulness, levels of arousal

24

pons

relays info from cerebellum to the rest of the brain.

25

midrbain

(tectum, tegmentum) arousal, mood, motivation.

26

tectum

orientation

27

tegmentum

movement and arousal

28

forebrain

(cerebral cortex, subcortical structures)

29

cerebral cortex

outermost layer of brain. perception, emotion, movement, thought

30

subcortical structures

centre of brain

31

thalamus

transmits info to the cerebral cortex

32

hypthalamus

regulates body temp, hunger, thirst, sexual behaviour.

33

pituitary gland

releases hormones

34

hippocampus

new memories

35

amygdala

emotional memories

36

basal ganglia

directs intentional movements.

37

occipital lobe

process visual info

38

parietal lobe

process info about touch.

39

temporal lobe

hearing and language

40

frontal lobe

movement, planning, memory

41

purkinje

info from cerebellum to brain and spinal cord

42

pyramidal

cerebral cortex

43

granule

info from mossy fibres

44

refractory period

dead time between one action potential and another

45

brocas

language production

46

wernickies

language comprehension

47

left/ right hemispheres

left (verbal) / right (spatial) or orientation of room

48

ventral

what/ temporal

49

dorsal

where/ parietal

50

transduction

encoded neural signals
