Regional Cerebral Blood Flow Miranda, Sarah, Tabea, Kirsten
Overview • Intro • Mainpart - Aim - Techniques • Conclusion - Results
Introduction • cerebral activation • deaf and hearing subjects • with deaf parents • deaf group depended more on spatial components
Mainparts • Aim: compare sign language lateralization and localization between hearing and deaf children of deaf parents • Techniques: high resolution rCBF system with 254 stationary detectors and 133 xenon inhalation used to measure
Conclusion • Results: deafness is the factor that explains differences in cortical activation • The enhanced right hemisphere parieto-occipital activation is an effect of a lack of auditory stimulation and of early learning of a visual-spatial language • This combination creates a different organization of language systems in the brain
