3
Q

4
Q

- neuroimaging
5
Q
ambidextrous
A
- both-handed
6
Q
Wernicke-Geschwind model
A
- Wernickes for meaning
- gets signal from ears
- Brocas makes words
- executes them via motor cortex
7
Q
Brocas
A
- mainly for grammar and verbs
8
Q
arcualte fasciculus
A
- transfer of meaning from Wernickes to Brocas
9
Q
most common cause for aphasias
A
- stroke / infarct
10
Q
apraxia of speech
A
- no cognitive impairement
- primary motor cortex damage
11
Q
anomic aphasia
A
- problems finding certain words
- which ones depends on brain area
- f.e. inferior temporal = objects,
- Brocas = verbs -> averbia
12
Q
posterior language area
A
words meaning
13
Q

A
- words recognition
14

A
= PWD
