Learning disabilities (LD) is experienced by 10% of the school aged children and are important causes of school evasion. Modern techniques of brain imaging allow neuroscientist a better comprehension of human cognition and to study neurocognitive development. The most popular among these techniques is fMRI, but it requires special facilities and is unfriendly to the children. The development of the microcomputers turned EEG recording very portable and allows it to be used at the school associated with very friendly computer games (CG) specially designed to study children neurocognitive development. Here, we describe an EEG brain mapping technique developed for such a purpose. The study of the brain activity during word and phrase reading by normal and learning disabled children is presented as an example of its application. The developed CGs were very effective in distinguishing children with a normal school development from those experiencing difficulties in reading.
