Addressing criticism for my Humans are metal robot story: I made no claim that an electronic transister experiences sensations. Going back to Peter Tse, neurons are coincidence detectors. Neurons detect information as coincidence patterns. The bit of the mind is a coincidence. The neural network builds concepts like an artificial neural network but one that is more evolved (by the age of life on this planet.) Perception is a rendered concept. Rendered by the brain to other parts of the brain in a fractal of feedback loops. I understand that neurotransmitters flow between chemical synapses. I am arguing that they represent a change in the placement of charged ions. Note: Calcium, potassium, and sodium ions are metals regardless of whether they are dissolved in aqueous cations. Look at a periodic table to see for yourself.
