Abstract: The seat of literacy Studying the changes that take place in the brain when we learn to read and write is very difficult because literacy is usually achieved during childhood, when many other developmental changes are taking place. An opportunity to use brain imaging to study the process arose when a group of former guerrillas in Colombia, including some who had not been taught to read as children, were being reintegrated into mainstream Colombian society. Comparing brain architecture of these 'late literates' to their illiterate compatriots highlighted a number of brain areas potentially involved in the acquisition of literacy. Interconnections between the left and right angular gyri in the parietal lobe emerge as important for reading irrespective of age of reading acquisition and ability.
