Anatomical investigations have suggested some form of abnormality in the cortex of dyslexic brains (Galaburda et al., 1985), yet other areas of the brain may play a part. The thalamus is almost certainly implicated in some aspect of language functions (Crosson, 1985) and has been shown to be under-activated in dyslexic adults in comparison with controls in some PET and fMRI studies (see Roush, 1995). Indeed, particular parts of the thalamus, the lateral and medial geniculate nuclei, have been said to be abnormal in dyslexia. To appreciate the significance of the findings, it is first necessary to consider the organization of the visual system.
