Research output: Contribution to journalMeeting abstract


The present study aims to further investigate the neural basis of speech perception in children with Autism Spectrum Disorders (ASD). Within ASD, communication is impaired and language functioning varies. Our research uses Magnetoencephalography to measure brain responses to matched speech and nonspeech stimuli. In our pilot study with healthy adults, we used a source localisation technique, known as Event-Related Beamforming and looked at the auditory Mismatch Field (MMF). The MMF provides a neuronal index of speech sound discrimination - crucial for language processing and development. Preliminary data from the pilot study with adults will be discussed. Based on previous research using other techniques, we predict aberrant brain responses in children with ASD, which is related to the child's degree of language impairment in autism.
