Every brain is unique, and scientists now have the means to pin down precisely how unique. Disease, environment, and genetic factors all influence the pattern of connections between neurons, called the local connectome. A new imaging technique quantifies differences between the local connectomes of individual brains, allowing researchers to identify a brain by its connectome “fingerprint.”
The technique uses diffusion MRI to track the movement of water molecules along pathways in the brain’s white matter, creating a fine-scale image of structural connections. The team took repeat MRI scans of a few individuals, and found that they could tell whether two local connectome fingerprints came from the same individual with 100 percent accuracy over the 17,398 identification tests they ran. The team’s findings were reported this ...
