Neuropsych - Language: Production, Comprehension, Aphasia

Exner's Area (BA 6), contributes to grammatic (graphomorphology) aspects of language (being able to write letters?)

Note that these are reciprocal pathways

-hearing loss (deaf in that ear)

Cortical deafness
-hearing loss/deaf

Arcuate fasciculus connects wernickes and brocca's-transduction aphasia (where you can't repeat what you hear) = understanding language but problems repeating.
-can't integrate what they are hearing with what they're articulating
-Understandable language
-repetition difficulties (phonemic paraphasias, eg saying things like uncle instead of brother, girlfriend instead of boyfriend)

-Non fluent,
-Language production problems

-receptive language problems

Hearing loss/deaf

-compiling a system of sounds and gestures in order to communicate.
-expressive, but also receptive-means of communication with expressive and receptive aspects-guided by rules, temporal organization (sequencing regulated by left hemisphere - regulated patterns), eg syntax (eg white house vs casa blanca)
-requires not just auditory pathways, but is rather very comprehensive. almost whole brain involved. so there is no consensus on a definition of language

Able to attach a category to everything we experience, every noun, eg like tagging it with a membership

Creates networks of schemes around concepts

-levels: eg pronouncing letters in order, and words have to be in oreder

-eg American sign language requires sequence of motion

-kids like at looking at lips movement, and how voice articulatessound (opposed to just listening to random sounds-at early stages we have level of language that is pretty standard, then start to specialize. Explains why adults who learn language have more of an accent than those who learn earlier

Smallest units of sound
