Human Brain has a Unique Fingerprint
A research team led by Carnegie Mellon University used diffusion MRI to measure the local connectome of 699 brains from five data sets. The local connectome is the point-by-point connections along all of the white matter pathways in the brain, as opposed to the connections between brain regions. To create a fingerprint, they took the data from the diffusion MRI and reconstructed it to calculate the distribution of water diffusion along the cerebral white matter's fibers.

  • Scientists Fingerprint Brain for the First Time
 

Apparently, scientists have found a method of creating a fingerprint profile of the human brain in all its complexity.

Via a novel imaging method, a map of the brain has been made that corresponds to the individual in the same manner as a fingerprint profile. MRI was employed to gauge the brain’s structural interconnections.

These were found to be unique and singular to each individual. Termed a brain fingerprint, this ID technique had 100% accuracy. Published in a research journal, the results showed that the special quality of the brain was such that it also got transformed over time. 

Such factors as disease, the environment and experiences form the brain’s structure and also count among the many influences that this fingerprinting method can lay out in the open.

It is a novel, benign, diffusion MRI method that catches a picture of the brain’s connections. The scale at which this imagery is taken is very up, close and personal (so to say).

The picture has been captured down to the level of a single brain cell. The biological bases and wired circuitry of the brain have been mapped down to the microlevel thanks to this methodology. 

The technique can be applied to both existent information and new data depending on the context. Both genetic and environmental factors can thus be tabulated in conjunction with the element of choice which lies open to the brain.

Whether the brain is able to cope with stress and function or unable to deal with stress and become dysfunctional, it all depends on many variables.

Diffusion MRI was used to measure the local connectome of 699 brains. The point to point connections count in the mix. The fingerprinting of the brain was accomplished through a complex and intricate process.  

A local connectome is unique to an individual. It is a good marker of a person’s identity. Over 17,000 ID tests were carried out. The differentiation of connectomes was accomplished after a lot of sifting of the wheat from the chaff.

Even identical twins only share 12% of the original connectivity patterns. These too undergo changeover every 100 days down to 13% of the stuff they are made of. The connectivity patterns are unique to the individual down to the microscopic level.

This research, published in PLOS Computational Biology, points the way to shared experiences and their imprints on the brains of various people. Such markers as poverty or epidemiology can be judged better via this methodology. It carries great scope for the future.
