Instant Genius is a bite-sized masterclass in podcast form. And in this episode, we're exploring dyslexia.

About 1 in 10 people in the UK have dyslexia, which is a neurological difference that can result in difficulties learning to read and write. But what exactly causes it? Scientists aren’t in full agreement, but our guest this episode – Professor Usha Goswami, a leading neuroscientist at the University of Cambridge – poses one intriguing theory.

Her work so far suggests that dyslexia is not a visual disorder, but rather a difference in how sound and rhythm are processed in the brain. She joins us to explain all.
