The five senses that humans are born with are sight, hearing, touch, taste and smell. Each of these five senses provides information to our brains that is received, processed and stored for future reference in our memories.
Scientists learn more and more about how the five senses work as time goes by but they still don’t know everything that there is to know. Of the five senses that we are born with, the one that is usually least developed is our sense of smell and it is the sense that scientists seem to really know the very least about. They know how it works, of course, but they really don’t understand how smells, scents and odors are processed in our brains or what reactions that they cause.
