21
Q

Why do you usually have left neglect rather than right neglect?

A

because the right hemisphere will cover both the right and left hemisphere so if you knock out the left hemisphere your right hemisphere will have you covered, but if you knock out your right hemisphere you will only be able to see the right side of the world (cuz thats all the left hemisphere gives you)

25
Q

What is this:

an inability to recognize the faces of familiar people, typically as a result of damage to the brain.

A

prosopagnosia

26
Q

How can you get prospagnosia?

A

lesion of right temporal lobe

27
Q

(blank) is a partial object agnosia in which the failure is in the ability to identify individual members of a category or set while retaining the ability to identify the category

A

Prosopagnosia

28
Q

What happens if you have a right frontal lesion?

A

aprosodias
“missing the point”
motor program deficits

29
Q

(blank) is a neurological condition characterized by the inability of a person to properly convey or interpret emotional prosody. Prosody in language refers to the ranges of rhythm, pitch, stress, intonation, etc.

A

aprosodias

30
Q

What happens if you have a lesion to the left frontal lobe?

A 
expressive aphasias (can use words with emotions like swear words but other words come out with great effort)
motor program deficits (typically dyspraxia i.e no language deficit just problem making speech)
31
Q

How can you tell if someone has dyspraxia versus aphasia?

A

they cant write if they have aphasia

32
Q

Do women or men recover better from strokes?

A

women

33
Q

(blank) is a form of aphasia in which the patient is unable to recall the names of everyday objects.

A

anomia

34
Q

When can you get anomia?

A

if you have a left temporal lesion

35
Q

What happens if you have a left parietal lesion?

A

receptive aphasia (temporal-parietal border)
acalculia
right-left confusion

36
Q

Left parietal zone is specialized for (blank)

A

lanugage

37
Q

Wernickes aphasia is what kind of aphasia?

A

receptive aphasia (cant understand what people are saying)

38
Q

What happens when you get damage to your frontal lobe?

A

loss of ability to form or follow plans (thus overreactive to immediate stimuli)
defects in the impulse to act (too much or too little)
dysexecutive syndrome
apparent loss of motivation
disinhibition

39
Q

What can huffing cause?

A

Damage to frontal lobe :(

40
Q

What happened to the guy that had the bar through his frontal lobe?

A

he lost inhibition and control, i.e. his personality changed, but his functionality was fine

41
Q

Why were frontal lobotomies (leukotomy) popular?

A

made people docile

42
Q

(blank) involves the compromise of essential language (symbolic) functions while leaving sensory and motor components of verbal (and written) communication intact

A

Aphasia

43
Q

What is expressive aphasia?

A

broca’s aphasia (understand but cant express speech)

44
Q

What is receptive aphasia?

A

wernickes aphasia (speech is fluent, dont make sense, dont understand)

45
Q

What is a rare diconnection aphasia?

A

conduction aphasia

46
Q

What is this:
An acquired language disorder, it is characterized by intact auditory comprehension, fluent (yet paraphasic) speech production, but poor speech repetition)

A

conduction aphasia

47
Q

Where is brocas area?

A

frontal lobe

48
Q

Where is wernickes area?

A

temporal/parietal border

49
Q 
What are these:
Post mortem studies
Commissurectomies (split brain studies) 
Sodium amytal
Electrical stimulation of surgical patients
Structural imaging 
Functional imaging
A note with regard to false color
A

ways to establish lateralization

50
Q

Whats worrisome about false color? How does it work?

A

you can distort data and use it for abuse :(

gives a certain density a color

51
Q

What hemisphere does this:

analysis of right visual field

A

left hemisphere function

52
Q

What hemisphere does this:

sterogenosis (right hand)?

A

left hemisphere function

53
Q

What hemisphere does this:

lexical and synatic language

A

left hemisphere function

54
Q

What hemisphere does this:

writing, speech?

A

left hemisphere function

55
Q

What hemisphere does this:
analysis of left visual field
stereogenesis (left hand)

A

right hemisphere

56
Q

What hemisphere does this:

emotional coloring of language

A

right hemisphere

57
Q

What hemisphere does this:
spatial abilities
rudimentary speech

A

right hemisphere

58
Q

In split brain indiviuals, when you put an item in their right visual field they were (not able/ able) to say what they saw.

A

Able! because their left hemisphere does speech (however if you put an object on your left visual field they couldnt say it but may be able to draw it)

59
Q

How can normal people see something in their left visual field and still be able to say whay they saw?

A

because the corpus collusum allows for communcation between hemispheres

60
Q

Where do you find asymmetry in thre brain that is found near the wernicks area, it allows hetermodul info to converge here?
What does it do exactly?

A

planum temporal
(there is also a smaller one near brocas area)
we dont know!!!!

61
Q

Left handedness is associated with greater (blank) as opposed to superiority or inferiority of a given talent, skill, or disability

A

variability
