Imagining the action and doing it require the same motor and sensory requirements in the brain. For example, when you imagine the letter B with your eyes closed, your brain lights up in the same way it would if you were actually looking at the letter on the screen.
Imagination and action follow the same neuro-pathway. They both influence each other where physical and mental practice result in similar outcomes.
1 group practices playing the piano physically, while another group pretends to play the piano but without actually touching the keys. This produced the exact same change in the cortex of the brain of both groups. Neuron connections are also strengthened when gaining muscles is physically and mentally done.
Take a look at AsapSCIENCE, and see how neurons can adapt to your way of thinking.
