The study suggests that OSA itself is sufficient to cause these deficits, rather than being solely attributed to co-morbidities.
A study found that bilingual readers process Latin and Chinese characters in different ways due to the formation of specialized cortical areas within the Visual Word Form Area (VWFA). In English-Chinese bilinguals, areas were only stimulated by recognition of Chinese logograms, while English-French bilinguals showed equal activation fo...
