Synopsis
Despite its essential use as a model for neurological disorders in humans, the rhesus macaque lacks a comprehensive MRI-histology-based segmentation of subcortical regions. Here, we mapped the subcortical regions in the macaque monkey using MAP-MRI, and postmortem histology of the same brain. Our results demonstrate that, at high spatial resolution, MAP-MRI can distinguish a large number of gray and white matter structures in deep brain areas. The ability to delineate and validate these in a given subject is useful for neurosurgical planning and navigation of implantable devices to potential targets for deep brain stimulation in the macaque model of neurological or psychiatric disorders.
