Yale study: Brain activity as unique as fingerprints

The phrases “as unique as fingerprints” and “as individual as snowflakes” might soon be joined by the saying “as different as brain activity” in the wake of a new study led by researchers from the Yale School of Medicine. The study, published Oct. 12 in the journal Nature Neuroscience, showed that researchers were able to identify people solely by looking at his or brain “connectivity profile.” These scans can be used to predict someone’s intelligence, and one day might help doctors predict or even treat neuropsychiatric illnesses, said Emily Finn, a Yale Ph.D. student in neuroscience and a co-first author of the paper. The researchers compiled functional magnetic resonance imaging — or fMRI — data from 126 subjects who underwent six scan sessions over two days. Subjects performed different cognitive…
