1

receptive language

brain derives meaning from auditory speech or visual language input

-comprehension

2

expressive language

brain produces spoken or written language output to communicate meaning

-production

3

anomia

difficulty finding words

-difficulty generating the words used to label things in the world.

4

dysarthria

difficulty controlling the muscles used in speech

-difficulty saying words

5

apraxia

impairment of motor planning of speech articulation

-difficulty pronouncing words

6

aphasia

deficit in language comprehension or production

7

historically Broca's area has been associated with speech production...what new information do we have on this topic

-Broca’s area does not participate in production of individual words, but coordinates the transformation of information processing across large-scale cortical networks involved in spoken word production, prior to articulation.”

- Connects representations of words in temporal cortex to motor areas for articulation

8

Wernicke's area is associated with speech comprehension deficits ...how has this view recently changed

there isn’t a completely clear association with lesions in Wernicke’s Area and Wernicke’s Aphasia – also involves surrounding tissue

9

mental lexicon.

the collective store of information about the semantics, syntax, orthography, and phonology of words

10

what is the neural correlated of the mental lexicon

-inferior and medial temporal cortex
-left temporal lobe

11

process of spoken word comprehension and neural correlates

-PMTG :posterior middle temporal gyrus
-MTG: middle temporal gyrus

-ITG: inferir temporal gyrus

-PCC: posterior cingulate cortex

12

process of written language comprehension and neural correlates

-left occipitotemporal cortex

13

language production ...neural correlates

-inferior temporal
-left frontal operculum (Brocas)
-motor cortex
-supplementary motor area
-insula
-basal ganglia
-cerebellum
-thalamus

14

language is in left or right hemisphere

left

15

which brain area connects words to motor

Broca's area

16

which area connects auditory input to words

Wernicke's area

17

which area links words to meaning

supra marginal gyrus

18

which area links visual words to meaning

angular gyrus

19

area responsible for auditory processing

STG (superior temporal gurus)

20

mental lexicon brain area

temporal lobe

21

mental lexicon... how it is organized semantically

-morpheme : cup, cake ,s
-frequency: accessed more quickly

-semantic relationships

-lexical neighborhood: bat, cat, sat
