Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Here the structures are organized into a hierarchy that corresponds to the classical nervous system hierarchy of NeuroNames ( Bowden-1995 and ‘About BrainInfo’ in the sidebar). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta).
