Document Summary

Examine the anatomy- select 1 or 2 sections from the handout. Aphasia: that was the beginning of cognitive neuroscience, it was not called that till about the 1990s- but it is really human cognition and the brain. Wernicke- lesions in the posterior temporal region in the left hemisphere caused severe language disorders. These are characterized by comprehension problems, not production problems. Very soon afterwards, people started to think of language production in a holistic manner- something called the wernicke geshwind model- the first to propose it, and then in the 1970s- geshwind reactivated his model. Defining areas=impossible questions to answer, but we will try. The model- in the left hemisphere, typical right-handed person with language dominance in the left hemisphere, there is a production area in the ventralalateral frontal region. Central sulcus- everything infront is the frontal lobe- ventral part of the lateral hemisphere and we can divide it into the dorsal- dorsal means above and ventral means above.
