Researchers from the Max Planck Institute for Cognitive and Brain Sciences have found that reading aloud and “to yourself” engages different brain regions related to movement, hearing and information processing. The findings are published in the journal Neuroscience & Biobehavioral Reviews (NBR).
Scientists analyzed data from more than 150 studies in which participants read letters, words, pseudowords (sets of letters without meaning), sentences and texts in different languages. The brain activity of the volunteers was monitored using fMRI.
It turned out that reading letters activates mainly one area in the left occipital cortex, while words and whole sentences activate wider areas, including the left temporo-occipital and inferior frontal gyrus. These areas respond differently to words and pseudowords, indicating their specialized functions in processing written information.
In addition, the scientists found significant differences between overt (aloud) and covert (to oneself) reading. The first variant activates brain areas associated with movement and hearing, while the second is associated with coordination between different cognitive systems.
The researchers paid particular attention to how the brain distinguishes between explicit and implicit reading. For example, areas of the left orbitofrontal cortex, cerebellum, and temporal cortex were activated during silent reading of words and pseudowords. At the same time, lexical decisions - determining whether a set of letters is a word - engaged both inferior frontal and insular areas.
The authors emphasize that the results help to better understand the neurobiological basis of reading and may be useful in developing methods for diagnosing and treating speech and cognitive disorders.
