Disturbance of the auditory cortex in Autism Spectrum Disorder (ASD) is well known as well as its influence on hearing. Functional connectivity within the brain is also known to be affected by ASD. However, functional connectivity of the auditory cortex in ASD has yet to be studied. In this study, using resting-state functional magnetic resonance imaging data from the Autism Brain Imaging Data Exchange (ABIDE), functional connectivity of the auditory cortex was examined by comparing 68 individuals with ASD and 75 individuals with ASD. Four brain regions showed smaller functional connectivity to and from the auditory cortex; the occipital cortex, motor cortex, insular cortex, and Wernicke’s area. All these regions have been previously shown to be influenced by ASD. Smaller function connectivity to these regions may partly explain deficits in verbal communication of ASD.
