Q

Genetic foundation for language?

A

FOX P2 gene demonstrates deficits in sequencing articulatory patterns (ex: problems with pronunciation, syntax, and grammar)

Differences in gross anatomical structures between those who were affected and those who weren’t by the gene.

Q

Wernicke’s aphasia?

A

Difficulties in language comprehension
May not understand, so they put out meaningless sentences even though it is intact

Q

What is conduction aphasia?

A

Poor speech repetition.

The result of the damage between Broca’s area and wernicke’s area.

IMPORTANT for the consideration of connectivity

16
Q

What are the 2 ventral pathways?

A

Post TL -> ant TL/IFG
- Word comprehension

17
Q

What are the 2 dorsal pathways?

A

Post TL — IFG
- preparation for production
BA44 —> post STG
-syntax processing

18
Q

What is the ventral pathways responsible for?

A

Sound to meaning: sounds to objects (words, grammar)

19
Q

What is the dorsal pathways responsible for?

A

Sensory to motor; sounds to actions (phonemes, production); syntax (rules of sentence structure)
