Meet Dr Hannah Critchlow of Cambridge University, a passionate neuroscientist and powerful storyteller who spoke at the Hay Festival in Wales earlier this year about the brain and human creativity, analysing the brainwaves of her audience using an EEG kit and PowerLab and wiring up a writer to show how the creative brain goes about composing a difficult chapter. We spoke to Hannah about the festival, her love of neuroscience and what inspires her.
