Sorry Guys, But Women’s Brains Mature Faster

Sorry Guys, But Women's Brains Mature Faster A new study discovers brain networks reorganize their connections throughout life to improve efficiency.

Investigators discovered the process begins earlier in girls, which may explain why they mature faster during the teenage years.

Newcastle University scientists studied individuals 40 and younger and found that the brain re-organizes connections throughout our life.

Dr. Marcus Kaiser and Sol Lim found that while overall connections in the brain get streamlined, long-distance connections that are crucial for integrating information are preserved.

The researchers suspect this newly-discovered selective process might explain why brain function does not deteriorate — and indeed improves — during this pruning of the network.

Interestingly, they also found that these changes occurred earlier in females than in males.

“Long-distance connections are difficult to establish and maintain but are crucial for fast and efficient processing, said Kaiser.

“If you think about a social network, nearby friends might give you very similar information — you might hear the same news from different people. People from different cities or countries are more likely to give you novel information.

“In the same way, some information flow within a brain module might be redundant whereas information from other modules, say integrating the optical information about a face with the acoustic information of a voice is vital in making sense of the outside world.”

As explained in the journal Cerebral Cortex, researchers at Newcastle, Glasgow and Seoul Universities evaluated the scans of 121 healthy participants between the ages of 4 and 40 years.

The study sample represents the age range where the major connectivity changes can be seen during this period of maturation and improvement in the brain.

Using a non-invasive technique called diffusion tensor imaging — a special measurement protocol for magnetic resonance imaging (MRI) scanners — they demonstrated that fibers are overall getting pruned that period.

However, they found that not all projections (long-range connections) between brain regions are affected to the same extent; changes were influenced differently depending on the types of connections.

Projections that are preserved were short-cuts that quickly link different processing modules, e.g. for vision and sound, and allow fast information transfer and synchronous processing.

Changes in these connections have been found in many developmental brain disorders including autism, epilepsy and schizophrenia.

The researchers have demonstrated for the first time that the loss of white matter fibers between brain regions is a highly selective process – a phenomenon they call preferential detachment.

They show that connections between distant brain regions, between brain hemispheres, and between processing modules lose fewer nerve fibers during brain maturation than expected.

The researchers say this may explain how we retain a stable brain network during brain maturation.

Commenting on the fact that these changes occurred earlier in females than males, Lim said: “The loss of connectivity during brain development can actually help to improve brain function by reorganizing the network more efficiently.

“Say instead of talking to many people at random, asking a couple of people who have lived in the area for a long time is the most efficient way to know your way.

“In a similar way, reducing some projections in the brain helps to focus on essential information.”
