Why Reading Brains Are Different – And Why It Matters for Humanity

Tuesday, January 21, 2025.

Have you ever wondered how reading reshapes your brain?

In a world dominated by scrolling and streaming, reading books might feel like a lost art.

But recent research reveals something fascinating: good readers actually have distinct brain structures.

This insight is more than just a fun fact—it carries profound implications for our individual lives and society.

The Decline of Reading in a Digital Age

Reading for pleasure is increasingly rare.

According to The Reading Agency, 50% of UK adults don’t read regularly, up from 42% in 2015. Among young people aged 16-24, nearly one in four has never been a reader. As screens take over our attention, what are we losing?

This cultural shift may be more than a preference for videos over text. It could be changing our brains in ways we don’t fully understand. New research published in Neuroimage explores how good readers' brains differ from the rest of us.

Reading and the Brain: What Makes a Good Reader?

Using open-source data from over 1,000 participants, scientists have pinpointed two critical areas in the left hemisphere of the brain that set good readers apart: the anterior temporal lobe and Heschl’s gyrus.

• The Anterior Temporal Lobe: This area helps link and categorize information, playing a key role in understanding language.

  For example, when you think of the word “leg,” this region connects its appearance, feel, and movement into a unified concept. Larger anterior temporal lobes correlate with stronger reading comprehension.

• Heschl’s Gyrus: Nestled in the upper temporal lobe, Heschl’s gyrus houses the auditory cortex, a hub for processing sounds. Reading may seem like a visual skill, but phonological awareness—matching letters to sounds—is foundational. The auditory cortex supports this skill, and its structure directly influences reading ability.

What Makes a Reader’s Brain Different?

The study found that good readers tend to have larger anterior temporal lobes, which help process meaning. They also exhibit thicker left Heschl’s gyri, supporting more advanced phonological skills.

Interestingly, this variation isn’t limited to those diagnosed with dyslexia, a condition often associated with a thinner left Heschl’s gyrus.

Instead, it spans the entire population, suggesting that reading ability exists on a spectrum shaped by brain structure.

Size Isn’t Everything: Why Brain Shape Matters

When it comes to brain structure, bigger isn’t always better. The “balloon model” of cortical growth explains that areas with more myelin—a fatty substance insulating nerve fibers—become flatter and more extended.

In the left hemisphere, where language processing occurs, this results in thinner but larger cortical areas capable of rapid, precise communication.

For complex tasks like reading and phonology, a thicker cortex in certain areas, like near the left Heschl’s gyrus, may enhance integration of sensory inputs into coherent speech sounds. In short, the brain’s adaptability and specialization are key to reading success.

Can Reading Change Your Brain?

Yes, and the evidence is compelling.

The brain is highly plastic, meaning it can change and adapt based on what we do. Studies show that intensive language learning increases cortical thickness in language-related areas. Similarly, regular reading can reshape brain regions like the anterior temporal lobe and left Heschl’s gyrus.

For example:

• A study in Journal of Neuroscience (2021) found that adults who practiced reading unfamiliar scripts, like Braille or foreign alphabets, showed increased activity in their temporal lobes.

• Research published in Developmental Cognitive Neuroscience (2022) revealed that children who engage in daily reading develop stronger connections between auditory and visual processing centers.

This means it’s never too late to benefit from reading. Your brain continues to evolve, shaping neural pathways that influence how you think, communicate, and process the world.

The Broader Implications of Reading

If reading becomes less of a priority in society, the consequences could be far-reaching.

Reading fosters empathy, critical thinking, and the ability to interpret the world around us. Without these skills, we risk losing a fundamental aspect of what makes us human.

In fact, a study published in Psychological Science (2020) showed that reading fiction enhances empathy by helping readers understand others’ emotions and perspectives.

Another study from Frontiers in Psychology (2021) found that frequent readers are better equipped to navigate complex social situations, thanks to their ability to process and interpret nuanced information.

Why You Should Pick Up a Book

Reading is more than a pastime—it’s an investment in your brain and your humanity.

By reading regularly, you’re nurturing the neural architecture that supports literacy, empathy, and communication. You’re also contributing to a culture that values depth, connection, and understanding in an increasingly superficial world.

So, the next time you choose a novel over Netflix, remember: you’re doing more than enjoying a good story. You’re strengthening your brain, fostering empathy, and playing a small but vital role in preserving humanity’s ability to connect and understand.

The science is clear: reading reshapes your brain for the better. It enhances your ability to comprehend, connect, and thrive in an increasingly complex world. So grab a book, settle into your favorite chair, and let the pages work their magic—not just on your mind but on humanity’s future.

Be Well, Stay Kind, and Godspeed.
