Which of the three brain cells in our brain is responsible for consciousness? Do we need to be conscious? Where are the connections between the brain and our bodies? What's the connection between a cell's electrical signals and its reaction to chemical signals in our brain? Can we get a better picture of the brain? How many different kinds of cells are there in the human brain? Can our brains be upgraded? Will our brains ever be more like robots? Are there any risks of having too much brain power? I'm on a plane and I can't talk to anyone. Am I crazy? Is my head full of electricity? I am a neuroscientist. I am an electrical engineer. I am a neurosurgeon.
