POL SCI 2 Lecture Notes - Lecture 9: Local Field Potential, Multielectrode Array, Speech-Language Pathology
Document Summary
The study of the function of separate parts of the brain began with observation of cases of speech pathology: These findings lead to active searches for facts which would show disturbances of higher cortical functions in circumscribed brain damage have local significance -> local diagnostics of brain damage. Hughlings jackson, broca"s opponent, proclaimed the idea that a disturbance of higher cortical functions should be regareded as a regression of functional organization on a lower level rather than lesions in local parts of the brain. Narrow localization approach: elementary + higher mental functions can be localized to limited parts of the brain. Loss of specific function damage in limited area of brain. Antilocalization approach: elementary functions are linked to limited brain parts, higher mental functions are related to the whole brain. Loss of higher mental functions damage of the whole brain, general brain symptom.
