Document Summary
What has been found: category-specific deficits: some people cannot recall names of tools, animals, etc, w-g model doesn"t account for all the structures responsible for producing language. If i had a stroke that damaged the articulate fasiculus, what language deficit would i have and why: broca"s aphasia, since the articulate fasiculus. *can insert foxp2 gene into mice to see if they perform better in language comprehension tasks (ex. maze running), and it works! Development of prenatal brain: starts as flat tissue of ectoderm, center of tissue folds in and creates a valley, walls of valley fold over, join at top, central underground river develops underneath, neural tube forms. Brain development: the corpus callosum is medial to the cerebral hemisphere. T: the cns/bone both develop from endoderm (middle layer). F: cns/skin develop from ectoderm (top layer, during development stem cells all over the brain divide and migrate to their appropriate location before differentiating.
