We follow neuroscientist Adrian Owen’s gadabouts through the Secret Garden Party in July 2010 – from raves to our secret island hideaway to – with a handy Sensecam, a nifty device that takes a photograph every few seconds to create a continuous record of all his experiences.

“Almost everything you experience is laid down in your brain, somewhere, but for the most part we can’t access it,” he explains. The most interesting part about the Sensecam record, he believes, is what it teaches us about human memory: only the things we might want to remember are actually made available for easy access. “And this shows us how important social interactions are for constructing memories… a large component of ‘memory’ is what you were thinking or feeling at the time you experienced these events.”
