When we look back at scary situations, they often seem to have occurred in slow motion. Eagleman wanted to know whether the brain’s clock actually accelerates - making external events appear abnormally slow in comparison with the brain’s workings - or whether the slo-mo is just an artefact of our memory.
It’s just one of many mysteries concerning how we experience time that we are only now beginning to crack. “Time,” says Eagleman, “is much weirder than we think it is.”

Perhaps time is to audition what space is to vision.
