PSYC 311:
Week 2 Lecture 6: neuroanatomy of language
Announcement and review:
- Coursepack is reserved in the library
- Introduce the basic symbols which essentially is the beginning of our field
- Schematic diagram of the brain draw on board
- Damage in different parts can cause different cognitive problems
- Broa’s area: Area , , ae 7/:
o Broca is a physician and anatomists
o Specific lesion in a specific part of the brain
o Responsible for language production
o It makes sense that the language production is in front of motor area
- Wernicke:
o Patients who have damage in superior temporal gyrus has comprehension
problem:
▪ Inability to speak and comprehend problem
o Wernicke’s area: Critial area of oprehesio of laguage
o If you open up sylvian fissure, you can see the primary auditory cortex, makes
sense comprehension is located at superior temporal gyrus
- Problem with Wernicke’s area ad Broa’s area:
o The damage is quite broad, a relatively cross area
- How are these areas connected?
o Probably by a pathway underneath the insula.
▪ Failed to find the pathway from the lateral temporal to inferior frontal
gyrus
▪ The field said there is a pathway from the posterior part of the temporal
lobe and arches around the Sylvia fissure: Arcuate fasciculus
- Right next to superior temporal gyrus, sits another gyrus: the middle temporal gyrus:
o It has long connection goes to the parietal gyrus:
▪ Parietal gyrus: Critical for reading and writing, and there is a lot of
communication. An area where multiple sources of information come
together
- Disease: make a messy lesion.
- Conduction aphasia:
o Destroy the arcuate fasciculus
o Comprehension and production area of the language are disconnected
o Patients seem to talk fine, they make a lot of paraphasia: spook or spoon
▪ Knife when they meant spoon
- Warrington:
o When there is a disease, you not only cut arcuate fasciculus, but also destroy
Supramarginal gyrus.
▪ It could be the damage of arcuate fasciculus, or it could be that you
destroy supramarginal gyrus.

Document Summary
Introduce the basic symbols which essentially is the beginning of our field. Schematic diagram of the brain draw on board. Damage in different parts can cause different cognitive problems. Bro(cid:272)a"s area: area (cid:1008)(cid:1008), (cid:1008)(cid:1009), (cid:373)a(cid:455)(cid:271)e (cid:1008)7/(cid:1005)(cid:1006): broca is a physician and anatomists, specific lesion in a specific part of the brain, responsible for language production. It makes sense that the language production is in front of motor area.
