AbstractManganese enhanced MRI (MEMRI) is capable of detecting layer specific interhemispheric somatosensory connections. In this study, Mn2+ was injected into the right visual cortex for tracing interhemispheric visual connections in normal and monocularly enucleated rats. In consistent with classic histological tracing studies, Mn2+ enhancement in the left hemisphere was concentrated within a narrow bi-laminar stripe. Upon left eye enucleation, which making the right cortex largely deprived of visual stimulation, the Mn2+ transfer dropped by 18.5%. These results for the first time demonstrated that MEMRI is capable of tracing layer-specific transcallosal connectivity of visual cortex and is sensitive to activity modulation. (Abstract by ISMRM)
