Abstract

Abstract Functional imaging studies have established cortical networks forreading alphabetic, syllabic and logographic scripts. There is little information aboutthe different cortical areas that participate in reading an alphasyllabary. We usefunctional brain imaging to study the reading network for Devanagari, an alpha-syllabary. Similar to syllabic scripts, the basic phonological unit that corresponds toa grapheme in Devanagari, called an akshara, is a syllable but the componentconsonant and vowel within akshara can always be visually analyzed giving it theappearance of an alphabetic system. Unlike an alphabetic system whereinarrangement of consonants and vowels is linear, in Devanagari, vowels can also beplaced linearly in a sequential manner or non-linearly, above or below, making itvisuospatially complex. In this study we used functional neuroimaging to ascertainthe cortical reading network when 10 native speakers of Hindi, read linear words inDevanagari. Akin to other word reading studies, we find activation in the mid-fusiform gyrus (visual word form area, BA 37). Region of interest analysis showsinvolvement of left superior temporal gyrus (BA 41), inferior (BA 40) and superiorparietal (BA 7) lobules. These findings suggest that the reading network forDevanagari, an alphasyllabary encompasses cortical areas involved in reading bothalphabetic and syllabic writing systems
