Synopsis

Keywords: Brain Connectivity, fMRI (task based)Multisensory integration is necessary for the animal to survive in the real world. Multiple studies with conventional methods established the multisensory integration process in multiple brain areas. This study aimed to investigate interactions between visual and somatosensory networks in a whole brain scale using 15.2T BOLD fMRI with the assistance of cortical silencing by optogenetic stimulation.Keywords: ultrahigh field fMRI, optogenetics, multimodal integration.
