Despite having made rapid strides in understanding the cosmos, subatomic particles, molecular biology, and genetics, we still know very little about the organ that made these discoveries possible. How does the activity of 100 billion nerve cells—mere wisps of protoplasm that constitute the brain—give rise to the broad spectrum of abilities that we call consciousness, mind, and human nature?
