Brain networks important for reading and language comprehension

In a series of projects, we are studying how different parts of the brain work together in a network while we read or understand speech. We want to know what brain network dynamics can tell us about individual differences in children’s reading and language skills.

Think about what your brain is doing as you read the word on this page.

Most likely it is activating the parts of your brain that allow you to recognize the way letters and words look, sound and how they form meaningful words and ideas. Most previous studies of reading development have focused on each of these processes separately (“functional specialization”). Here we are using new advances in computational neuroscience to study how these processes coordinate their activity throughout a network (‘functional connectivity”). We find that brain network dynamics during reading and language comprehension tasks show strong correlations with children’s reading and vocabulary skills.

Being about to efficiently integrate the way letter combinations look with how they sound is the hallmark of skilled reading. We think studying this integration directly with EEG could provide a sensitive measure of the neural plasticity associated with learning to read.
