A new study shows that the sense of smell is more influenced by other senses and relies more on predictive coding compared to sight and hearing. The research highlights how the olfactory system is uniquely proactive, using both olfactory and visual brain areas to process unexpected smells.indicates that the sense of smell is significantly influenced by cues from other senses, whereas the senses of sight and hearing are much less affected.
To figure out more about how smell relates to how we handle different sensory impressions, the researchers conducted a study with three experiments, two behavioral experiments, and one experiment using the brain imaging method The study shows how important it is for our different senses to be able to use correct cues when we classify different sensory impressions.“We have all experienced that we react to when an unexpected smell appears, for example when we enter someone’s flat and encounter a new smell.
“The olfactory brain thus has a completely unique way of processing smells and it is about whether the smells are expected or not. The sense of smell warns us of smells that we had not expected, and engages the visual brain, perhaps to be able to see what it is that smells. It’s a smart function because we humans are so bad at recognizing smells if we don’t get clues,” says Jonas Olofsson.
