A major meta-analysis from researchers at the Max Planck Institute has produced the most detailed map yet of how the brain engages with reading. By synthesizing findings from 163 prior studies, the review clarifies that reading recruits a broad neural network—primarily in the left hemisphere—rather than a single “reading center.” The study, published in Neuroscience & Biobehavioral Reviews, offers insights that can influence classroom practices and interventions for reading difficulties in Thailand and beyond. Data from leading research institutes shows that reading involves complex coordination from letters to full texts.
Reading remains a foundational skill for education, employment, and social life. In Thailand, where reforms emphasize literacy across regions and populations, understanding the brain basis of reading has practical implications for teachers, students, and policy makers. The researchers emphasize that reading relies on a distributed network rather than a single area, with the cerebellum and traditional left-hemisphere language regions playing key roles across tasks from decoding letters to comprehending sentences.
Across more than 150 functional neuroimaging studies in alphabetic reading tasks, the analysis identifies distinct brain patterns corresponding to different levels of reading complexity. Letter recognition activates a small cluster in the left occipital cortex, while reading words, sentences, or longer passages engages additional regions, including the left inferior frontal gyrus and the left temporo-occipital areas. The brain’s flexibility in handling real words, pronounceable non-words, and full sentences underscores how learning to read adapts to language demands.
The study’s lead authors stress the enduring importance of left-hemispheric language areas and the cerebellum for reading. The cerebellum, often associated with movement, emerges as a steady contributor to literacy, underscoring literacy as a physical and cognitive process. These findings reinforce the idea that reading is an embodied activity involving coordinated brain systems.
A key distinction arises between overt reading (reading aloud) and covert reading (silent). Reading aloud more strongly engages auditory and motor regions tied to speaking and hearing. Silent reading, by contrast, relies more on cognitive control and working memory. This distinction helps explain differences in instructional approaches for diverse learners in Thai classrooms, including strategies for early readers and bilingual contexts. Explicit silent-reading tasks activate left orbito-frontal, cerebellar, and temporal regions, while implicit tasks involve broader frontal and insular networks.
Educators emphasize the broader implications for teaching. Literacy is linked to social connection, education, and well-being. For Thai schools, understanding the neural basis of reading can inform targeted methods, including tailored reading strategies, bilingual programs, and interventions for dyslexia and related learning difficulties. Such insights support Thailand’s move toward inclusive, equity-focused education and a knowledge-based economy.
In Thailand, disparities in reading achievement persist alongside regional and socioeconomic differences. Integrating neural-informed approaches into curricula—acknowledging cognitive and neural diversity—can help close gaps and improve outcomes as the country advances literacy goals. The Thai education system, with its rich linguistic landscape, can adapt by combining letter-level, word-level, and sentence-level activities, both in Thai and in second languages, to stimulate multiple brain networks.
Thai readers bring a unique cultural tapestry to literacy. From traditional scripts to modern graphic novels and digital media, reading in Thailand blends heritage with innovation. While the current review centers on alphabetic reading, its overarching message—that reading engages dynamic, distributed brain networks—offers relevance for syllabic and logographic scripts as well, particularly for ethnic languages and multilingual contexts in the kingdom.
Looking ahead, researchers suggest that distinguishing brain processes behind different reading tasks may improve diagnosis and intervention for reading disorders. For Thailand, this could translate into more precise supports for students who struggle with literacy, helping to narrow the learning gap and promote inclusive education.
Practically, Thai educators are encouraged to mix reading activities—letter by letter, word by word, and sentence-level comprehension, in both spoken and silent modes—to activate varied neural pathways and deepen literacy. Parents can support children through shared reading experiences, alternating aloud and silent reading, and exploring diverse texts across languages and genres.
As neuroscience advances, the path to expanding literacy opportunities in Thailand feels increasingly grounded in evidence. For all Thais pursuing personal and national development, strengthening literacy remains a cornerstone of social progress and lifelong learning.
