JAKARTA - Since ancient times, humans have been said to have the most common senses commonly referred to as the five senses, namely the eye of the sense of sight, the nose of the sense of smell, the ear of the sense of hearing, the sense of touch, to the sense of taste. However, now researchers believe that humans have more than 5 senses.
"My long-term collaborator, Professor Charles Spance of the Crossmodal Laboratory in Oxford, says that his colleagues in the field of neuroscience believe that humans have between 22 and 33 senses," said researcher from the University of London, Barry Smith, quoted from Science Alert.
Some of the other senses referred to are proprioception, which allows humans to know the position of body parts without having to see them. In addition, there is also a sense of balance that involves the vestibular system in the ear canal, vision, and proprioception.
Then there is the sense of introsepsis, an ability to feel changes in one's own body. For example, there is an increase in heart rate or the emergence of hunger.
"We also have the sense of agency when moving the body, a feeling that we are the ones who control the movement. In stroke patients, this sense sometimes disappears, until they feel as if someone else is moving their arm," he explained.
Some of the common senses, according to Barry, are a combination of several senses. For example, touch actually includes pain, temperature, itching, tactile sensations.
Then when tasting food, the three senses are also actually involved, namely touch, smell, and taste. The three of them together form the taste of food and drink.
"Taste allows us to know the taste of salty, sweet, sour, bitter, and umami," he said.
"Around us there are always many things that show how complicated the work of the senses is, as long as we want to stop for a moment and really feel it. So, the next time you walk outside or enjoy food, take a moment to appreciate how your senses work together, helping you feel the whole experience," he concluded.
