You probably never think about what is happening in your brain when reading a text, your favorite book, or even an email. The brain plays an extremely important part in the reading process and it is essential to have a reading-ready brain. Thanks to advancements in neuroscience and technology we are now able to target key learning centers in the brain to identify areas and neural pathways that are employed while reading.

The Reading Brain At-a-Glance:
Research has discovered that brain activation patterns in poor readers differs from that of good readers
Brain is made up of two hemispheres (left/right); each hemisphere is divided into 4 lobes/sections (frontal, parietal, temporal, and occipital)
Left hemisphere is associated with speech, language processing, and reading
Left Hemisphere of the brain controls
Speech
Language Processing
Reading
Frontal Lobe controls
Speech
Reasoning
Planning
Regulating Emotions
Consciousness
Parietal Lobe controls
Sensory Perceptions
Links spoken and written language to memory
Temporal Lobe controls
Verbal Memory
Occipital Lobe controls
Identification of Letters
Within these lobes there are additional areas that provide crucial support for skilled reading:
Broca's Area > organization, production, manipulation of language and speech
Parieto-Temporal Area > analyzes words by pulling them apart and linking the letters to their sounds (decoding)
Occipito-Temporal Area > identifies words rapidly and automatically on sight (doesn't analyze by sound)
This video provides a brief explanation, and introduction, to the Reading Brain.
When we read, our brains transform the shapes of letters and characters on a page into the sounds of spoken language. But how does the brain do this? That’s what cognitive neuroscientist Stanislas Dehaene is trying to find out.
According to Dr. Carolyn Strom, the Clinical Assistant Professor of Early Childhood Literacy at NYU Steinhardt says, "We are not connected to the Orthographic form (written), we actually need to create a circuit called the Phonological Route. Then eventually we create the Lexile Route, which is when words are retrieved faster and stored in memory." (Beyond the Buzzwords: Using the Science of Reading for Impact, Amplify Virtual Symposium 2021)
When Dr. Strom discusses the reading brain with educators and families she has found it better to utilize game graphics and refer to the areas as 'neighborhoods' to keep the conversation from getting "mired with technical jargon."
These 'neighborhoods' are broken down into:
Sound City (phonological)
Mountains of Meaning (semantic)
Vision Villages (orthographic: objects and faces)
There is no village for recognizing words
