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.

Where the brain retains memories

For the first time in the history of research, scientists were able to identify what they think are the places where memories are formed and stored our. Briefly, neurons working with information about who we are and about the things you've done or I've lived in the past.

"Because we were able to highlight these places in laboratory mice brains, hopefully we can get to know more about how memories are formed in our brains," said the researchers behind this study

Queensland Brain Institute - University of Queensland

A team from the Institute of Neurobiology in France have made this discovery by using a fluorescent protein in neurons of four mice. This protein illuminate the cells containing calcium ions, in this case showing that the existence of the respective neuron functions.

Laboratory mice were tested so as they ran on a running wheel. During the "race" their neurons were lit, which means that in their minds already formed memories that helped them remember the distance traveled. When the animals were resting, light only appear in certain parts of the brain representing that there is stocaseră information that helped the rats to remember different parts of "race" covered.

"We managed to outline how memories are formed," explained Rosa Cossart, study leader.

Of course, the study was questioned by other researchers who claim that you can not know for sure if these neurons are indeed those responsible for storing memories. They argue that there is no reason why that experience for the running wheel mice on them to be stored in memory and divide into distinct cell blocks. However, these studies represent an interest for them, only to be taken further, detailed and analyzed in other ways.


Currently scientists clear a few aspects regarding how the storage of memories in the brain, such as that in the hippocampus there are cells that help the rats to remember the surrounding world, but they could not explain at this time how and why illuminate these neurons and that this process has traveled to the brain.
