Know how a whiff of certain odours can take you back in time, either to a great memory or bad one? It turns out emotion plays an even bigger role with the nose, and that your sense of smell actually can sharpen when something bad happens.
Northwestern University researchers proved the surprising connection by giving volunteers electric shocks while they sniffed novel odours. The discovery, reported in Friday’s edition of the journal Science, helps explain how our senses can steer us clear of danger.
More intriguing, it could shed light on disorders such as post-traumatic stress syndrome.
