Surprising new discovery: The brain continues to mature until the age of 30 years

The human brain does not fully mature until the age of 30 years. The new discovery raises questions regarding punishment of criminals under 30 years.

For the most sophisticated processes such as attention, perception, decision-making and risk-taking, the brain begins reaching maturity until the fourth decade. Both in the UK and the USA ,, maturity '' a person is a key factor regarding the investigation of a person.

Stages of brain development before birth ResearchGate

In a report by the House of Common Select Committee has recommended that young adults aged between 18 and 25 to be treated differently from older criminals in May. The report suggests that most young people involved in crime stop at the age of 25 years.

One of the greatest difficulties to establish when the brain is mature is the discovery of a man whose brain has matured. The key change that occurs in adolescence until age 20 and 30 years is thinning gray matter and white matter thickening.

Increased white matter is to increase connectivity between different brain regions. The brain that continues to develop is the prefrontal cortex. This area of ​​the brain located in the front of the head is involved in the activation of important factors such as attention, planning, decision making, control, logical thinking, personality development and short-term memory.

The discovery that changes everything about the human brain "Cartographers of the Brain"

Updated: 28/04/2020

The new map will help scientists better understand the new unknown areas of the human brain.

A team of researchers created the most detailed map of the human brain, skull radiographs using more than 100 people, to identify nearly 100 new regions of the cerebral cortex.

The new map defines 180 cortical areas, which helps scientists to understand better how we think, talk or feel, giving them new information about conditions such as autism, schizophrenia and dementia.

,, The brain is like a computer that can support any operating system and can run any software, "said neurologist David Van Essen, the University School of Medicine, St. Louis, Washington.

,, In fact, the operation mode is related to the structure of the brain. If you want to know what the brain can do, you should know as organized and connected, '' added the American scientist.

To build the map, the researchers used information from the Human Connectome project, a study was conducted long-term and consisted in the creation of over 1,200 radiographs of young adults with a custom MRI.

Information in this group, the researchers examined radiographs of 210 people, men and women. The radiographs were recorded measurements of the participants' cerebral cortex, the area that controls memory, thinking, speaking and consciousness.

Volunteers brain was scanned at rest and when the participant carry light loads, to be able to measure brain activity effectively.

By using an algorithm specially developed by researchers at Oxford University in Britain, scientists were able to identify distinct parts of the brain.

To ensure that the results are correct, scientists compared them with those obtained from investigations made on another group of 210 people.

Over 180 new regions were discovered in each of the two hemispheres of the brain. 83 have been identified in previous research, and other 97 new zones have been identified in the new study.

,, There is a clear distinction between new parts discovered. In fact, the transition is gradual, indicating a mixture  and coordination between different sensory modalities and cognitive domains, "said the scientists.

Some regions are more understandable than others. One of the regions 55b is activated when we hear a story being related to language. Other researchers, however, are new and hard to understand, because some areas are related to many functions of the brain, which mean it takes a long time until specialists can understand the whole map of the brain.
