In this abstract, we use high resolution 3D T1-weighted MRI at 7 Tesla to image cortical organization in four female common marmoset monkeys (Callithrix jacchus) based on patterns of myelin density. Using surface rendering techniques, we present 3D and flattened annotated maps of the cortex based on images from a representative marmoset. We also characterize major cortical features including the primary visual, somatosensory, auditory, and motor areas based on their surface areas measured over the four animals.
