Study of single sweep event related brain potentials in dyslexia

Abstract

The study of event-related potentials in dyslexic children requires particular attention in the definition of the clinical and analysis protocols. The clinical protocol here described was studied for the analysis of the different functions involved in the reading process. The analysis procedure is aimed to the reduction of ocular artifact, to the extraction of single sweep responses, to the estimation of parameters for the characterization of the processes involved in the reading function. A group of normal and dyslexic children was studied, and different mechanisms were evidenced during the reading function, through the evaluation of the activation sequence of the involved cortical areas.
