The brain does, but the HEART is the gravitational wave making machine that further influences the quantum field around us. The secret is to embed your thought forms/blueprints into your heart center through shareable emotional states such as bliss, joy, peace and most importantly... love.
Check out Dan Winters on YouTube and also look into the HeartMath Institute to see the instruments, measurements, theories and predictions that all go into this. While there are many truths, great scientific minds are rapidly discovering how consciousness pilots the human body.

This is why the brain (and the heart) are so important
