Document Summary
Neuroscience 101 exam i review part ii. L-handed individuals may have reversal of hemisphere dominance altogether. Brain regions are specialized for categories of word meaning and for specific functions. Ex: wernicke"s (speech comprehension) and broca"s (speech production) Ex: motion words activate motor regions, visual words activate visual regions: words are not exclusively processed by language regions of the brain. Different languages may be placed differently in the brain, and native vs. second languages may be represented differently. First/native language is typically tightly organized in terms of neural circuits in the l hemisphere. Bilingualism is neurologically beneficial: improves attentional ability (managing 2 languages may help brain sharpen and retain ability to focus while ignoring irrelevant info, protects against onset of alzheimer"s. A child"s language system is not just immature versions of an adult"s brain language system. Imaging proves word recognition at 13mo recruits both l and r hemispheres, but by. 20mo, it"s mostly condensed to the l hemisphere.
