Fat in the ear determines musical talent?

Researchers have found that whether you play a good instrument can depend on a fat in your ear.

According to new research published in Science magazine, a fat covering and insulating nerves, called myelin , is essential for the learning process of our brain's new skills. Researchers claim that when a person learns a skill, such as hitting the piano, later in life, myelin needs to be produced to maintain that skill.

Although, previous studies on white matter reveal the relevance of myelin to learning skills, but new research is the first to validate this through testing. Experiments on mice show that new myelin must be formed each time a biology learns a new skill later in life, and the white matter structure changes in new practice activities by increasing the number of sacrifices. cells producing myelin are called oligodendrocytes .

These findings may prove important for finding ways to stimulate and improve learning as well as understanding the relevance of myelin to other brain processes, such as cognition.

When a child learns or an adult acquires some new skill such as juggling, the brain needs to form new circuits and connect over long distances, with high velocities between different parts of the brain as well. like spine.

Professor Bill Richardson, director of the Wolfson Biomedical Research Institute (USA), emphasized: "These discoveries are really interesting, because they open up opportunities to explore the role of oligodendrocyte and myelin cells in the past. Other brain processes, including cognitive activities oriented in a labyrinth, to see if the requirement for general myelin formation or just for motor activity.

I would love to find out the exact order of changes to oligodendrocyte and myelin during the learning process and whether these changes have different levels of necessity in different parts. The answer may reveal some mysteries that still surround how the brain adapts and learns for life. "
