People often say: "The brain works differently for different people." A team of scientists led by researchers from Carnegie Mellon University recently proved it literally. Researchers have developed a “fingerprinting” method of the human brain using magnetic resonance imaging, finding that the structural brain compounds are so unique in each case that they can be used as an identifying factor for each individual.
According to the article published in the PLOS journal, they used the results of an MRI scan of the brain of 699 volunteers. In each case, the method of diffusion MTP was used. This is when a quantitative measurement of the diffusion of water molecules in biological tissues is carried out and on this basis a contrast three-dimensional image of the brain is created.
After the procedure, the scientists took the results and calculated the distribution of water in individual compounds (called a local connection). The researchers found that each person has a unique local connection, actually performing the function of a kind of fingerprint. It turned out that even connectomy twins are only 12 percent identical to each other. To test their discovery, scientists drove 17,000 identification tests. The result was stunning, showing almost 100 percent accuracy.
Scientists have found out both. It was found that people's life experiences, such as unhealthy lifestyles and diseases, affect the structure of the brain. In other words, scientists based on this information can develop methods to determine how the environment and experience transferred form the brain of people. Whether such a method will be used in the future as an identification of people is still difficult to answer. Now scientists are more interested in the medical potential of their knowledge.
Timothy Versteinen, one of the researchers at Carnegie Mellon University, comments:
“This confirms the fact that we in neuroscience have always just assumed: the connections in your brain are unique and peculiar only to you. This means that, in some way, all the life experience you have had is reflected in these compounds in your brain. From this point on, we can start research and try to figure out how the general experience, such as poverty and hunger, as well as the same pathological diseases, can affect the connections in your brain. This may contribute to the discovery of potentially new biomarkers to reflect certain health problems. ”
