Sight, Sound, Smell, Taste, and Touch: How the Human Body Receives Sensory Information.
When we think of human senses we think of eyesight, hearing, taste, touch and smell.
Humans have five senses: the eyes to see, the tongue to taste, the nose to smell, the ears to hear, and the skin to touch. By far the most important organs of sense are our eyes. We perceive up to 80% of all impressions by means of our sight.
Taste, smell, vision, hearing, touch and… awareness of one’s body in space? Yes, humans have at least six senses, and a new study suggests that the last one, called proprioception, may have a genetic basis. Proprioception refers to how your brain understands where your body is in space.
It doesn’t take much reflection to figure out that humans possess more than the five “classical” senses of sight, hearing, taste, smell, and touch. Because when you start counting sense organs, you get to six right away: the eyes, ears, nose, tongue, skin, and the vestibular system.
Taste is a sensory function of the central nervous system, and is considered the weakest sense in the human body.
How do the senses work? Your brain collects information, like smells and sounds, through your five senses: sight, hearing, touch, taste, and smell. Each of your five senses has its own special sensor. Each sensor collects information about your surroundings and sends it to the brain.
Most people are familiar with the five senses – sight, hearing, smell, taste and touch. However, we also have two additional senses. Watch this video to learn about vestibular and proprioception, senses, and visit our Sensory page to learn more.
July 8, 2021 — Humans have a sixth sense that most of us aren’t using, but could learn to. … But according to two recent studies, people can tap into a so-called sixth sense and learn how to navigate through darkness when our eyesight can’t break through.
Human external sensation is based on the sensory organs of the eyes, ears, skin, vestibular system, nose, and mouth, which contribute, respectively, to the sensory perceptions of vision, hearing, touch, spatial orientation, smell, and taste.
However, there are two more senses that don’t typically get mentioned in school — the sixth and seventh senses – that are called the vestibular and proprioceptive systems. These systems are associated with body movement and can lead to difficulties with balance when they don’t work correctly.
Perception is based on the interpretation of signals sent to the brain by the five senses. Each sense — touch, smell, taste, sight, hearing — affects how we react to the world and how we interpret events around us. The senses can alter a memory; if someone meets a person…
Ask children to think about the important features that the person is missing. Prompt them to suggest that the figure needs eyes. Follow the same procedure and add ears, nose, mouth, and hands. Explain that seeing, hearing, smelling, tasting, touching, and feeling are the five senses.
Our sense of smell in responsible for about 80% of what we taste. Without our sense of smell, our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter and the newly discovered “umami” or savory sensation. All other flavours that we experience come from smell.

The test itself is quick and easy and is conducted by placing four tiny strips of paper on the tongue, one at a time. After each strip, Dr. Barham and his team asks the person to report flavor and intensity on a scale of 1-10. For example, the strip could taste very bitter or mildly bitter.
Anosmia, also known as smell blindness, is the loss of the ability to detect one or more smells. Anosmia may be temporary or permanent. It differs from hyposmia, which is a decreased sensitivity to some or all smells.
Senses are important because they allow us to perceive the world in which we live. Our five senses are our sense of sight (also known as vision), smell (olfaction), hearing (audition), taste (gustation), and touch (somatosensation).
Hearing is our fastest sense. (Who knew?!) Horowitz says that it takes our brain at least one-quarter of a second to process visual recognition.
Decades later, researchers hypothesized that the exceptional ability that smells have to trigger memories — known as “the Proust effect” — is due to how close the olfactory processing system is to the memory hub in the brain.
Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin. Touch isn’t just a sense used to interact with the world; it also seems to be very important to a human’s well-being.
Sensory overload can happen to anyone, but it is more common in autistic people and people with ADHD, PTSD, and certain other conditions. It causes feelings of discomfort and being overwhelmed. Moving away from sources of sensory input, such as loud sounds or strong smells, can reduce these feelings.
Plants, animals and humans can sense fear or danger through a fine sense of smell or odor detection. Some do it through sensing subtle vibrations. Finely tuned standard senses may explain some psychic powers certain people seem to have.
There’s a quirky phenomenon where people who lose one sense can gain near-super abilities in another, especially if that sense is lost early in life. Blind people may hear better; the deaf can have a type of enhanced vision.
