The Mind Electric

IN SOME WAYS, the nervous system is like a thunderstorm, the controlled chaos of gathering electrical activity occasionally rendered visible in a bolt of lightning. The delicate skin of every neuron is studded with proteinaceous pumps that siphon positively charged ions—potassium, sodium, calcium—out of the cell and into its watery surroundings

… another part of me, standing at the neurologist's side, felt brilliantly alive—as if I were witnessing something miraculous, an alchemical transformation from a series of minute observations about someone's body to an essential truth, equal parts deduction and ritual. In my three years of medical school, I had already started to learn that there
