Brain activity as unique as fingerprints

Brain activity as unique as fingerprints

People already accept the fact that every human being is an individual with his or her own personality and idiosyncrasies; even twins or multiple children born from the same womb differ and are totally unique. Although fingerprints have long been used as identifiers, a new study has proof that even our brain activity has the capacity to showing unique patterns.

Yale University recently published a research paper based on that very principle. They found unique patterns in the brain activity identified by scans using a functional magnetic resonance imaging (fMRI). The brain scan produced a cognitive fingerprint of the brain and, to an extent, can now supposedly be used to diagnose the intelligence level of each human being.

The experiment was done using brain scans of participants as they performed an activity and again while they rested. Scientist studied more than 268 parts of the brain, more than 6 times each. When the researchers made identifications of the participants using the fMRI scans of active participants, they were 99% accurate. However, that accuracy level dropped to 80% when they compared the scans while the participants rested or did another activity which wasn’t as intense at the first activity.

Other than identifying the profile of a person, brain activity can also provide a glimpse of the intelligence level that a person can achieve in an intelligence test.

This new revelation comes with a caveat that this could be misused or worse, taken for granted if such scans were to be administered for a job interview or when applying for college. However, it is exciting to see how the brain activity will help doctors use it for therapeutic purposes.
