25
Postsynaptic Neuron
neuron that receives the charge
26
Postsynaptic Potential
when a charge is being transferred
27
Excitatory PSP
tells next neuron to fire
28
Inhibitory PSP
tells next neuron not to fire
29
Neural Impulses
brain's language
30
Vesicles
small bubbles that carry neurotransmitters
31
Receptor Site
specific place in neurons for certain neurotransmitters to bind
32
Binding
when a neurotransmitter finds a site to attach to
33
Reuptake
after binding a neurotransmitter will be re absorbed by the presynaptic neuron
34
Serotonin
Sleep, feel good, low levels are correlated with depression
35
Dopamine
"feel good" too little = schizophrenia too much = parkinson's
36
Acetylcholine
helps aid in movement
37
Norepinephrine
"no friend"= depression
38
Endorphins
released with exercise
39
GABA
related to anxiety, low GABA = high anxiety
40
CT Scan
brain structure, cheap ok picture
41
MRI
brain structure, expensive clear picture
42
PET
brain function, what part is being used
43
fMRI
brain structure and function
44
EEG
brain waves
45
Height
aka amplitude
46
Wave Length
aka frequency
47
Beta Waves
type of waves when awake and alert
48
Delta Waves
type of waves when in deep, dreamless sleep
49
Agonist
acts like/mimics a neurotransmitter
50
Antagonist
blocks a neurotransmitter by blocking a receptor site
51
System
brain or body parts work together to complete a function
52
Localization of Function
individual brain/body parts work alone to compete a function
53
Cerebrum
higher thinking, judgement, planning ect.
54
Thalamus
all sensory info passes through (except smell)
55
Hypothalamus
4 F's feeding, fighting, fleeing, mating, autonomic nervous system, and endocrine system
56
Endocrine System
includes hormones and glands
57
Hormones
chemicals in the body that permanently change appearance ot temparaly change mood
58
Glands
parts of the body that secrete hormones
59
Pituitary Gland
"master gland" located in the brain
60
Corpus Callosum
connects and allows the two hemispheres to communicate
61
Cerebellum
controls balance
62
Hippocampus
in charge of memory
63
Amygdala
controls emotions especially anger and fear
64
Pons
sleep
65
Medulla
breathing
66
Reticular Formation
pain perception muscle reflexes breathing sleep
67
Limbic System
hippocampus amygdala thalamus hypothalamus
68
Parietal Lobe
touch, on top
69
Frontal Lobe
movement
70
Occipital Lobe
back, sight
71
Temporal Lobe
hearing,side
72
Broca's Area
left frontal, important in speaking
73
Wernicke's Area
left temporal, important in understanding language
