Possibility to more accurately analyze parts and features of the human brain by new brain mapping

ByDigitalRalph

"Brain map" which expresses the connection and work of the parts by dividing the brain by each part has been made for more than 100 years ago. Neuroscientists at St. Louis - Washington University Medical School create new brain maps that divide the brain into 180 parts based on hundreds of human brain data, and more accurately determine the shape and function of each part of the brain You can grasp it.

You can see the movie you can see well about the newly created brain map from the following.

The explorer has made a map every time he finds out a new world and has revealed the shape of the world.


Likewise, neuroscientists also are trying to draw the brain structure as a map by clarifying the connection and work of parts of the brain.


However, it is easy to say "to make a brain map" with words, but it is difficult to actually create.


In order to make the brain map base, it is easy to describe the characteristics and shape of a part of the brain, the connection with other parts, and the cell shape of each part.


In 1909, an early brain map created by German neuroscientist Corvinian Broadman was "Broadman's brain mapIt is also known as a modern neuroscientist. On Broadman's brain map, the shape of the cells is depicted in different parts of the brain.



However, the brain map to be completed differs considerably depending on what characteristics of the brain are focused on. Among neuroscientists, opinions are divided on the total number of parts of the brain and the function of each part.


This time, the team of David Van Essen and others of St. Louis - Washington University Medical Graduate School have succeeded in making the most accurate brain maps so far. In this brain map, we divide the brain into 180 parts.


It also depicts 97 new parts of the brain that have been used by hundreds of brains and have not been clarified so far.


One of them is "Area 55b". On the research team, we speculate that Area 55b is the area responsible for language.


This is because the area 55 b moves actively when the brain processes languages.


The figure showing the connection between the area 55 b and other parts is as follows.


However, it is not yet clear how much isolated neurons in area 55b are isolated.


Therefore, it is important to integrate all data and study. By creating a new brain map, neuroscientists may finally be able to clearly define the boundaries and areas of parts of the brain.


The data that became the source of the brain map is summarized in "Human Connectome Project".
