Due to a combination of genetic factors and individual life experiences, no one, including twins, shares the same brain anatomy, reveals a study that suggests the use of MRI on fingerprints for personal identification. Lutz Jancke, a professor at the University of Zurich, said: "The combination of genetic and non-genetic influences clearly affects not only how the brain works, but how it works.
Professional musicians, golfers or chess players, for example, have particular characteristics in the brain regions that they use the most for their professional activity.
However, shorter-lived events may also leave traces in the brain: if, for example, the right arm is kept motionless for two weeks, the thickness of the cerebral cortex in the areas responsible for controlling the immobilized arm is red
"We suspected that these brain-effecting experiments interact with the genetic makeup, so that over the years each person develops a completely individual brain anatomy," says Jancke. hypothesis, the team examined the brain of nearly 200 elderly healthy people using magnetic resonance imaging three times over a two-year period.
More than 450 anatomical features of the brain were evaluated, including total brain volume.
The researchers were able to identify an individual combination of specific brain anatomical characteristics for each, so that the accuracy of identification, even for very general brain anatomical characteristics, was over 90 percent. hundred.
"With our study, we were able to confirm that people's brain structure is very individual."
"Thirty years ago, we thought the human brain had little or no individual characteristics.Personal identification through the anatomical features of the brain was unimaginable.Personal identification by the anatomical features of the brain brain was unimaginable, "says Jancke
. However, the replacement of fingerprint sensors by MRI is unlikely, since MRIs are too expensive and time consuming compared to the proven and simple method. takes note of fingerprints,
