LINA02H3 Final: Linguistics A02 Notes for Final Part 2
Document Summary
Split-brain patient cannot name objects presented in their left visual field because there is no way for the visual signal to be sent to the left hemisphere & access linguistic knowledge. Results from dichotic listening and split brain studies also support the idea that language is left lateralized. While informative, the vast majority of this research relies on investigating the damaged brain. In last 30 years, significant technological advances have allowed us to image the healthy brain in real time. Use sophisticated techniques to probe questions of linguistic and psycholinguistic relevance. Measured through non-invasive recording from human brain (functional brain imaging: hemodynamic techniques. Positron emission tomography (pet) die injected into patient, its progression through body is traced. Functional magnetic resonance imaging (fmri): measurement of blood- oxygenation flow from outside usually time-locked to some event (word, speech sound, picture, etc: electro-magnetic techniques. Other levels of linguistic representation: n400 as an index of semantics. He spread the warm bread with butter.
