For a long time the scientists imagined that the brain was made up of a mass of tangled wires. However, new images captured by a powerful scanner show that its fibers are configured like a chessboard, displaying orderly cross-angles.
The study that came to this new conclusion was led by Van Wedeen, a researcher at Massachusetts General Hospital in the United States. “This grid structure is continuous and consistent across scales and can be found in humans and other primate species,” he said.
For Thomas Insel, director of the National Institute of Mental Health, the images obtained by the researcher represent a milestone in the history of human neuroanatomy. “This new technology may reveal individual differences in brain connections that may aid in the diagnosis and treatment of brain disorders.”
The team’s goal was an early dream of researchers, as the human cortex develops many folds, nooks and crannies, making the structure of the connections difficult to visualize.
If we compare the technology currently exists with the new images obtained, it is possible to affirm that before we knew only 25% of the brain and from now on we can increase that number up to 75%.
