ABSTRACT
We used functional magnetic resonance imaging (fMRI) to map the neural systems involved in reading Chinese in 125 participants 6-74 years old to examine two theoretical issues how brain structure and function are related in the context of the lifetime neural development of human cognition and whether the neural network for reading is universal or different across languages. Our findings showed that a common network of left frontal and occipital regions typically involved in reading Chinese was recruited across all participants. Crucially, activation in left mid-inferior frontal regions, fusiform and striate-extrastriate sites, premotor cortex, right inferior frontal gyrus, bilateral insula, and supplementary motor area all showed linearly decreasing changes with age. These findings differ from previous findings on alphabetic reading development and suggest that early readers at age 6-7 are already using the same cortical network to process printed words as adults, though the connections among these regions are modulated by reading proficiency, and cortical regions for reading are tuned by experience toward reduced and more focused activation. This fMRI study has demonstrated, for the first time, the neurodevelopment of reading across the lifespan and suggests that learning experience, instead of pre-existing brain structures, determines reading acquisition.
