La alteración de los ritmos cerebrales en la dislexiaUna prueba diagnóstica

Resumen

Investigations into the neuroanatomical bases of language processing have provided new insights to understand neurotypical speech perception and production and also the abnormal patterns underlying some pathologies, as developmental dyslexia. We assess here the contributions of new models, e.g. the Asymmetric Sampling in Time Theory (Poeppel, 2003) and the Multi-Time Resolution Model (Poeppel et al. 2008, Giraud and Poeppel 2012), together with their explanation of the difficulties found in dyslexic children in the Temporal Sampling Framework (Goswami 2011). Among these difficulties, apart from the well-known problems in reading and spelling, rhythm inaccuracies in production and perception have been noted long ago (Wood y Terrell 1998, among others). Nevertheless most of the experimental studies have been conducted in English, a language rhythmically very different from Spanish. Our goal is to propose a diagnostic test that considers the anomalies in the oscillatory response of the dyslexic population for an early detection of dyslexia in Spanish.
