Connectivity-Based Segmentation of the Precuneus in Individual Adolescent Rhesus Macaque DTI Data.

Connectivity-based segmentation of the precuneus, an important connectome hub, is performed on DTI data of young rhesus monkeys. We observe how the proportion of connections from the precuneus to functionally different brain regions (limbic, somatosensory, and visual) shifts with increasing age. This gives us valuable information for creating models of brain development.
