That brain cross five ageseach of which is linked to important changes Where connections between neurons they come redesigned. This is how the most complex organ l‘childhood That end around 9 years oldmarks the beginning of a long teenage years That only at the age of 32 years entering adulthood. Another crucial moment they happen in 66 yes 83 many years. This is demonstrated by research led by Alexa Mousley, from the University of Cambridge, published in the journal Nature Communications.
Like all other organs, although in different shapes and ways, too brain And dynamic and it connection structured between neurons they change over time. The transformations analyzed by British researchers used Magnetic Resonance scanning, which made it possible to map the various neural connections made on 3,802 people From aged between zero and ninety.
The data allows us to identify some real data turning pointsome of them very clearthat occurs throughout life.
In the first stage,childhoodthe brain has a sustainable growth gray and white matter, the two main tissues of the central nervous system, and are characterized by a wealth of connections which follows a pattern repeated from birth until about 9 years olda phase in which the brain experiences radical changes in cognitive abilities, as well as an increased risk of mental disorders.
The second age of the brain,adolescencestill looking white matter continue to increases in volume and organization communication network the brain becomes more refined. This is the phase where neural connections they become faster and more efficientchanges associated with improved cognitive performance. It is this transformation that achieves peak average in his early thirtiesi, the strongest turning point of the lifetime, researchers say.
“Around 32 years oldlet’s look at the main ones change of direction In cable and the largest overall trajectory shift, compared to all other turning points,” Mousley said longest erait’s fromadulthoodwhen brain architecture stabilizes compared to previous phases, with no significant turning point for thirty years. The phase corresponds to a “plateau of intelligence and personality,” the researchers said.
However, 2 other turning points let alone markedrecorded on average 66 And 83 years old.
