On its own, each neuron is inconsequential, a dumb oscillator, cycling endlessly through the same program. Fire and recharge. Fire, recharge. But through feedback loops and dense interconnections, neurons gently nudge one another towards synchrony, forming and breaking alliances signalled by their common rhythm. And it is through these rhythms, through the dappled waves of electricity rippling through the brain, that our experience of this universe arises…
