Good readers have different brains, says research

The number of people who read for fun appears to be steadily dropping. Fifty percent of UK adults say they don’t read regularly (up from 42% in 2015) and almost one in four young people aged 16-24 say they’ve never been readers, according to research by The Reading Agency.

But what are the implications? Will people’s preference for video over text affect our brains or our evolution as a species? What kind of brain structure do good readers actually have? My new study, published in Neuroimage, has found out.

I analysed open-source data from more than 1,000 participants to discover that readers of varying abilities had distinct traits in brain anatomy.

The structure of two regions in the left hemisphere, which are crucial for language, were different in people who were good at reading.

One was the anterior part of the temporal lobe. The left temporal pole helps associate and categorise different types of meaningful information. To assemble the meaning of a word such as leg, this brain region associates the visual, sensory and motor information conveying how legs look, feel and move.

The other was Heschl’s gyrus, a fold on the upper temporal lobe which hosts the auditory cortex (the cortex is the outermost layer of the brain). Better reading ability was linked to...
