‘Brain fingerprint’ is as unique as those on our hands

A new study from Yale University has concluded that brain activity is as unique as a fingerprint. The researchers see much potential in the technology, while others fear the onset of a brave new world, RT Reported.

“The patterns were different enough that we were able to pick people out of a crowd regardless of what people were doing,” study co-author and neuroscience doctorate student Emily Finn told NBC News.

Finn’s team enlisted the help of 126 patients previously documented in the Human Connectome Project (HCP), an ongoing project to collect brain-imaging, behavioral, and other information on healthy people. The patients were scanned six times each by an fMRI, a procedure that measures brain function and blood flow.

Two of the scans were of the mind at rest or adrift. The next four took snapshots of the brain during mental tests, from simple memory tests to more complex problem solving in order to judge “fluid intelligence.”

By the end of the scans, each patient had a “functional connectivity profile” recorded, and none were alike.

The hope from this is that future studies will be conducted on sick people to understand disease, or on young people to understand their best learning environment. Could a “functional connectivity profile” also predict tendencies toward addiction or violence?

Others fear learning too much about the brain or applying those lessons haphazardly. If indeed brain activity is driven by rare or exclusive factors present early in life, could people be discriminated against or “neurodiscriminated” against for employment, insurance, education, or in some other way have their lives predetermined?
