Functional Connectivity Of The Inferior Frontal Gyrus In Autism Spectrum Disorders, Emma Miller

Honors Theses

ABSTRACT

The American Speech-Language-Hearing Association defines Autism Spectrum Disorder (ASD) as a “neurodevelopmental disorder characterized by deficits in social communication and social interaction” which is heavily impacts language abilities. There is an abundance of research on the neurological aspects of the disorder, which appear to have major differences of activation and functionality when compared to typically developing peers. Specifically, in the left inferior frontal gyrus (IFG), a key language region of the brain, functional connectivity levels tend to be significantly less in ASD groups. This study recognizes these trends and aims to expand the research by locating specific functional connections …

The Functional Connectivity Of The Auditory Cortex In Autism Spectrum Disorder, Katherine Wilson

Honors Theses

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, …
