Flashcards in chapter 1 info neuropsych Deck (54):
1

frontal lobe

organization, direction, inhibition

2

parietal lobe

touch and proprioception (know where body is in space), synthesis

3

occipital lobe

visual

4

cerebellum

monitors and regulars motor behavior, learning and attention

5

brain stem

maintains homeostasis, controls autonomic functions (breathing, heart rate, blood pressure)

6

limbic system

instinct and mood, controls emotions and drives

7

corpus callosum

bundles of fibers that connect the left and right brain

8

temporal lobe

hearing, face/object recognition, emotional reactions

9

language in

left brain

10

logic in

left brain

11

calculations in

left brain

12

L/R orientation in

left brain

13

finger naming in

left brain

14

speech (motor movement)

left brain (brocas area)

15

right hemibody, hemispace

left brain

16

arousal in

right brain

17

spatial (neglect) in

right brain

18

visuomotor in

right brain

19

emotion in

right brain

20

awareness in

right brain

21

prosody (tone of voice)

right brain

22

left hemibody and hemispace in

right brain

23

neuropsychology is

the scientific study of the relationship between behavior and brain

24

the brain is

an old english word for tissue around skull, 2 symmetrical hemispheres connected by commissures

25

gyri

folds of cortex

26

sulci

creases between folds, fissures

27

forebrain

cerebral cortex, performs higher function like thinking, perception and planning

28

brainstem

underlying tube, performs regulatory and movement producing functions

29

spinal cord

connected to brainstem and descends down back, performs regulatory and movement functions

30

central nervous system (CNS)

brain and spinal cord, tissue doesn't regenerate after damage

31

peripheral nervous system (PNS)

somatic and autonomic, fibers that carry info to and from CNS, tissue can regenerate after damage

32

Aristotle's theory of the mind

psyche-nonmaterial, responsible for human thoughts perceptions and emotions, mentalism (idea that mind is responsible for behavior)

33

Descartes: mind-body problem

body is material and performs like a machine, while the mind is nonmaterial and decides what movements the machine should make. How can nonmaterial mind produce movement in material body

34

dualism

position that the mind and body are separate but interact

35

darwin and materialism

materialism is rational behavior can be fully explained by the workings of the nervous system

36

localization of function

idea that different parts of the brain perform different functions

37

Franz Josef Gali and Johann Casper Spurzheim studied depressions and bumps in skill

called phrenology-laid foundation for modern localization of function. cranioscopy is the method used to measure bumps and depressions for personality assessments

38

broca's aphasia

left hemisphere, problem producing speech

39

Wernicke's aphasia

left hemisphere, back of brain, understanding speech

40

wernicke produced

first model for organization of language. wernickes area connected to brocas aread via arcuate fasciculus-conduction aphasia. geschwind updated in 1960s

41

Flourens removed areas of cortex of animal brains and studied resulting changes in behavior

found no specialization for areas of cortex, specialization of brainstem, refuted localiztion of function

42

hierarchial organization

each successively higher level of the neurons system controls more complex aspects of behavior, after damage to higher level behavior becomes more simple

43

HM

amnesia, but could learn procedural memory, proves no 1 localization in brain for memory

44

ventral stream

"what" stream, mediates actions controlled by conscious visual perception

45

dorsal stream

"where" stream, vision for action without conscious awareness

46

neuron hypothesis

neurons: are discrete, send electrical signal, communicate with each other via chemical signal(neurotransmitter) across synapse

47

glia

nervous system cell, holds neurons together, carry out supportive functions

48

neurons

nervous system cell, acquire process and act on info, cell body, dendrites and axons

49

electrical activity

stimulates brain to induce movement, transcranial magnetic stimulation

50

Donald Hebb-Hebb or plastic synapses

when cells activated at same time, establish or strengthen the synapse, brain is plastic and constantly changing

51

brain imagine

produces 2&3 dimensional images of the brain using computers

52

computerized tomography (CT)

passage of xrays through head, quick and cheap

53

positron emission tomography (PET)

injection of radioactive substances into the blood, substance gives off photons as it decays, computers detect photon origins and construct image of brain

54

magnetic resonance imaging (MRI)

identifies location of moving molecules by detecting electrical charge generated by movement, high resolution
