Abstract
Audiovisual integration is the way the brain incorporates information from both auditory and visual stimuli. Although this has been studied, a true consensus on where it takes place has not been reached. The objective of this project was to localize the areas where audiovisual integration takes place using a coordinate based Meta-Analysis. This Meta-Analysis was conducted on 33 research articles, which were acquired based on the following eight criteria: the article must not be a review, must be a neuroimaging study, must be on audiovisual integration, must feature healthy participants, participants must be over the age of 18, the statistics had to be reported in MNI or TAL coordinates, the statistics had to be whole brain, and the article must be written in English. The coordinates acquired were put into GingerALE, providing a map of Activation Likelihood throughout the brain. These results identified the bilateral Superior Temporal Gyrus, Inferior Frontal Gyrus/Sulcus, and Fusiform Gyrus, supporting their involvement in audiovisual integration. These results have important implications for the future of audiovisual integration research, as future experiments can focus purely on these regions for more in-depth analyses to understand how and why audiovisual integration takes place.
