This paper forms part two of a review of the neurobiology of developmental dyslexia (DD) and here the focus is on magnetic resonance imaging (MRI) of the corpus callosum (CC) of dyslexic and non-dyslexic subjects. The CC is a bundle of nerve fibres connecting the left and the right hemisphere of the brain. Due to the role of this structure in inter-hemispheric transfer and integration between the
hemispheres, the CC is significant in the search for the neurobiological basis of DD. (S Afr Optom 2012 71(1) 39-45)
