There’s an old saying in neuroscience: “neurons that fire together wire together.” This means the more you run a neuro-circuit in your brain, the stronger that circuit becomes. This is why to quote another old saw, “practice makes perfect”. The more you practice piano or speaking a language, or juggling, the stronger those circuits get. Scientists have known this for years. However, nowadays researchers learn another part of the truth: In order to learn something, even more, important than practicing is the ability to unlearn or to break down the old neural connections. This is called “synaptic pruning”. This Is How It Works: Imagine your brain is a garden, except instead of growing flowers, fruits, and vegetables, you grow synaptic connections between neurons. These are the connections that neurotransmitters like dopamine, serotonin, and others travel across.
