The little grey cells that make up your mind are primarily neurons. You have approximately 100 billion of them in your head! With over a 1,000 trillion connections, or synapses, there are more transmission-pathways in your head than there are atoms in the universe. But before you let that go to your head, think about this: the number of synapses peaks in early childhood, so the average three-year-old has ten times as many as the average adult! Of course, a linear relationship between synaptic-density and cognitive ability has never been scientifically demonstrated. (If you need help with that sentence, ask a toddler.) All a single neuron can do is flash a small signal on to its neighbors. But working together, they bestow upon us action like an angel, and apprehension like a god. Or do our thoughts animate them?
