Document Summary
90% of pop is right handed, 10% is left or mixed. Of the pop that is right handed, 99% is left-hand lateralized for speech. Neurons in the left speech region of our brain our more complex the homologous right brain. A disorder of learned, skilled purposeful movement not related to muscles paralysis or comprehension deficits. Ideational inability to evoke the appropriate action representation from long-term memory. Ideomotor inability to translate the appropriate innovatory patterns into action. New form of apraxia as result of her lesion no difficulty with speech/language comprehension, no typical apraxia symptoms. There is a developmental form dyspraxia term used to described clumsy children: believed to arise from a soft deficit in left-hemisphere, difficulty sequencing movements. Wiring in brain is not fully developed and not allowing them to communicate effectively with the brain. Persons with down syndrome perceive speech with their right cerebral hemisphere. Probably not a good think because that hemisphere is not optimized for speech perceptions.
