What happens in our brains when we read?

Reading is an intriguing activity that uses a variety of brain areas. We all understand that reading is a necessary ability, but did you know that it exercises our minds similarly to weightlifting? The more we read, the stronger our neural connections get and the more proficient we become. But what happens in our brains while we read? This is a question that researchers have been attempting to answer for years, and a recent study has finally provided some clarification.

Oscar Woolnough, a neuroscientist at the University of Texas Health Science Center in Houston, performed a pioneering study that provided fresh insight into how language is processed in our brains. According to the research, reading activates two different brain networks.

In order to examine the brain activity of 36 individuals who had intracranial electrodes implanted as part of their epilepsy therapy, the research team adopted a novel methodology. The researchers were able to study how different areas of the brain cooperated to make sense of words by monitoring the cerebral activity of the participants while they read. The participants were given three different sorts of texts to read: meaningful sentences, lists of words, and “Jabberwocky” sentences, which used proper grammar but contained fictitious words. The outcomes were intriguing.

Their research found that two nearby brain networks work together to interpret what we read. As a person starts to understand the meaning of a sentence, the frontal lobe of the brain sends signals to the temporal lobe, activating the first network. Each word contributes to the overall message in this process, which is like putting together a linguistic jigsaw. Another region of the temporal lobe is used by the second network. It communicates with the frontal lobe once more. It’s interesting to note that words in a list rather than complete sentences were more likely to activate this network. This shows that the second network is essential for improving our comprehension of specific phrases.

“This study helps us better understand how distributed hubs in the brain’s language network work together and interact to allow us to understand complex sentences,” says Woolnough.

This ground-breaking study makes it possible to better understand how our brains handle language. It also paves the door for potential developments in neuroscience, artificial intelligence, and education. We can truly appreciate the incredible strength of our thoughts in making sense of the written word as we understand the intricate workings of our brains.
