BIL 268 Lecture Notes - Lecture 21: Korbinian Brodmann, Primary Motor Cortex, Auditory Cortex
Document Summary
Gene: foxp2 -looking at the genes of ancestors between primates and chimpanzees, and humans. Comparing genetics, humans only have two different genome sequences compared to chimpanzees. Left cerebral cortex dominant role broca"s area (frontal lobe) close to motor cortex and probably has to do with motor processing, speech. Wernicke"s area: temporal lobe near the primary auditory cortex. The discovery of specialized language areas in the brain. Wada procedure: used to determine hemisphere dominant for speech. Left side and right side are supplied by different blood vessels. If you inject cns suppressants, and carried out the left side of the hemisphere and then compared language processing. If the patient has damage to one of the language areas, they will have aphasia, lack of language communication due to illness or physical trauma. Wernicke aphasia- fluent aphasia- the patient can talk- sensory aphasia- problem is comprehension- they don"t understand the question.
