A detailed new map by researchers at Washington University School of Medicine in St. Louis lays out the landscape of the cerebral cortex – the outermost layer of the brain and the dominant structure involved in sensory perception and attention, as well as distinctly human functions such as language, tool use and abstract thinking. researchers discovered that our brain’s cortex, or outer mantle, is composed of 180 distinct areas per hemisphere.

  • Scientists Map the Human Brain up to its Minute Details

Scientists have managed to map the human brain up to its minute details. This has been a challenge yet it was accomplished in the end with a little extra effort.

A map is the best simplified representation of reality. Global maps help us in making sense of the world’s byways. Yet a map of the human brain could help neurologists and neurosurgeons gauge its functions.

Recently, the cerebral cortex was mapped. It is the brain’s outermost layer. The folds were divided into 180 regions in accordance with their functions. 

At least 97 of these regions have never been identified before. The novel brain map was published in a journal that goes by the name of Nature. Each area has its own unique structural-functional criteria and connectivity.

These areas have a high degree of contrast with each other in the same manner as countries. It had always been a dream of the scientists to divide up the brain into ever smaller pieces in order to find out more about it.

MRI scans show us the blood flow for various mental objectives. Up until now most maps of the human brain have been limited. They provide an incomplete picture of the contents of the cranium.

The new map of the brain uses MRI scans to offer us a more complete view. Among some of the measurements made are: cortical girth, the workings of the brain, inter-regional connectivity, organization of the cells and amounts of myelin.

Myelin is a fatty substance that speeds up neural signaling. The boundary lines were determined in the brain map. Many peoples’ brains were studied in order to construct this map. This study opens up the way for the exploration of the brain on an extensive basis.  

However, the map still leaves some things to the imagination. After all, the human race has an insatiable thirst for progress. Maybe in the future similar human brain maps will be constructed in the form of holograms.

To get to the triggering biochemical bases of the brain is the ultimate goal of neurology. Just to think that in the future, the brain would be mapped in every possible way like Google Earth tends to divide up the world into discrete units. That would be a miracle and it would lead to the eradication of many diseases and maladies too. 

This study got published on July 20 in the journal Nature.
