Nerve fibres in the brain could produce pairs of particles linked by quantum entanglement. If backed by experimental observations, this phenomenon could explain how millions of cells in the brain synchronise their activity to make it function.
“When a brain is active, millions of neurons fire simultaneously,” says Yong-Cong Chen at Shanghai University in China. Doing so requires even distant cells to coordinate their timing – but what mechanism do they use? “If the power of evolution was looking for handy action over a distance, quantum entanglement…
