From simple drum-type surfaces made from oatmeal containers to finely-tuned frequency generators and Tibetan singing bowls to substituting cultured heart cells for sand and salt that would sort to nodes and anti-nodes . We can learn a lot from how our own brains work by looking at the different ways non -traditional cognition works. One example is synesthesia , where sensory inputs get re-routed and/or amplified in an es...
