Document Summary

Following a stroke after the first few weeks usually leads to apraxia (either short term or long term) Stroke to right parietal lobe, patient could preform tasks flawlessly. Persons with down"s syndrome perceive speech with their right cerebral hemisphere speech perception. Probably not a good thing because that hemisphere is not optimized for. 90% of the population are right hand dominate. Of the 90%, 99% are left hemisphere dominate for speech and language. 90% of left hand dominate have speech and language lateralized to the left hemisphere as well. 50% of people with down syndrome are left handed fmri activates broca"s area (left hemisphere) in the general population fmri of people with down syndrome activate right hemisphere for the perception of speech. Model of reverse cerebral specialization: people with down syndrome have everything lateralized to the opposite side. Just like in the general population, speech production in people with down. Syndrome are also lateralized to the left hemisphere.
