This isn’t necessarily a new idea to many, the idea that participating in “music” one way or another promotes healthy brain growth/ stimulation.
As much as we claim to no know this fact, I feel there is very little we can truly speak on. This article talks about specific examples of neurological benefits, some of which including:
Musicians have an enhanced ability to integrate sensory information from hearing, touch, and sight.
The age at which musical training begins affects brain anatomy as an adult; beginning training before the age of seven has the greatest impact.
Brain circuits involved in musical improvisation are shaped by systematic training, leading to less reliance on working memory and more extensive connectivity within the brain.
