Our sense of smell can have a large impact on how we think and feel.But did you know that mood can affect how we smell?According to a study by researchers at the University of Wisconsin Madison, feeling anxious can make typically neutral smells seem repugnant.The study involved a dozen volunteers who rated a panel of neutral smells.Then, while inside an MRI machine, subjects were made to feel anxious with disturbing images of car crashes and grisly war scenes.They were then once again asked to rank the panels of neutral smells.But now, after having been made anxious by the images, they described some of the smells as negative. So, what's going on?MRI revealed that during induced anxiety, the smell related circuits of the brain became intertwined with the brain's emotional circuitry.
