How playing an instrument benefits your brain

Recent research about the mental benefits of playing music has many applications, such as music therapy for people with emotional problems, or helping to treat the symptoms of stroke survivors and Alzheimer’s patients. But it is perhaps even more significant in how much it advances our understanding of mental function, revealing the inner rhythms and complex interplay that make up the amazing orchestra of our brain.
Did you know that every time musicians pick up their instruments, there are fireworks going off all over their brain? On the outside they may look calm and focused, reading the music and making the precise and practiced movements required. But inside their brains, there’s a party going on.

Children with autism have extra synapses in brain: May be possible to prune synapses with drug after diagnosis

Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development, according to a study by neuroscientists at Columbia University Medical Center (CUMC). Because synapses are the points where neurons connect and communicate with each other, the excessive synapses may have profound effects on how the brain functions. The study was published in the August 21 online issue of the journal Neuron.

Loss of mTOR-Dependent Macroautophagy Causes Autistic-like Synaptic Pruning Deficits. Neuron, 2014; DOI: 10.1016/j.neuron.2014.07.040

In a study of brains from children with autism, researchers found that autistic brains did not undergo normal pruning during childhood and adolescence.
