Dr Kevin Fong is on a mission to find out how doctors can avoid making mistakes in the high-pressure, high-stakes world of the operating theatre.
Here he visits Michigan State University and is fitted with an EEG cap, which measures the electrical activity of the brain. It allows Jason Moser, a psychology professor and expert in error-processing in the brain, to see how quickly his brain responds to making mistakes.
