Document Summary

Transduction is how we get an external information into our head and interpret it. In olfaction, however, the mucous membrane of the nose senses the shape of the molecules in inhaled air, sends them to the olfactory nerve and to the limbic system. Many primitive reactions are linked to the limbic system (share limbic system with many other animals, even reptiles) Vision takes up the bulk of our detecting the external world. Olfaction, however, is the first sense to have likely evolved 100 000 000 years before the others: human sense of smell is one of the weakest in the animal kingdom. Humans may be able to fall in love via olfaction. Male smell may influence the female reproductive cycle: subliminal visual messaging does not influence behaviour, smells that we may not even detect may influence our behaviour. Lemon and peppermint makes people more alert. Spiced apple and vanilla made people more relaxed.
