3 Senses You Didn’t Know You Had

  • Added:  11 months ago
  • At some point, you’ve probably learned about the five senses: sight, sound, smell, taste, and touch. However, the classic list doesn't account for all the sensations we experience and use to navigate the world around us!

    When exposed to temperatures 60-70C I actually feel pleasure, like somebody gently scratching my skin. This is way above 40C when TRPV1 starts to indicate painful heat. I measured temperature I can withstand without getting annoyed -- it's about 75C. My wife constantly complains that tap setting is just crazy and can damage her skin and skin of our sun. How does it can happen?

  • Kurt Mill
    Kurt Mill 10 months ago

    I've read that the senses Smell/Taste can be collapsed into one, with Sight, Touch and Hearing also well known.
    Obviously, Balance/Vestibular is another one of our sense, and I'd say Orientation/Proprioception/Intuition accounts for knowing your location in space. So that's 6 senses.
    I'd say there's a 7th sense for knowing one's relativity in space, light, gravity and time too. Basically how everything else relates to us or to a common context.

      High school was mostly dull. I mean I had no problem averaging straight B's. It's just every now and then the system reared it's ugliness. They should have put more faith in the teachers. Because when it was up to them, things went right.

      NY. It was a rich school, mixed with some poor and middle class. Regents diploma sucked balls. You could get a 80% the whole year for a class, fail the final test; because you didn't study, and be forced to repeat it. This happened to me. I fought it, and was able to retake the test, which I easily passed.

      I still remember the guidance counselor. He was shocked I challenged the system. I kept to myself, never shook the boat. But when someone wants to mess up my world, expect me to fight back. The other time was to play Magic the Gathering. That went pretty well. At least we had a understanding principal.

      it doesn't sense sensory types, it just receives signals and processes the info it has. in fact, you could take the sensory input from your eyes and reroute it to your audio perception and your brain would start to hear your soght. it's strange how it works out. There are function fact checkings, though, which allow for the brain to change function locations. That's not really sensing, though, just logic processing.

    what is "room temperature"? Is it the same temperature everywhere and all the time? Why is it called "room temperature"?

    • Alexandra Mallory
      Alexandra Mallory 10 months ago

      +David Bhart So then it's 25C? I was just wondering, because the temperature in say, Australia without heating or cooling would be warmer than the temperature without heating or cooling in Antarctica. Thank you for the info!!!


    • David Bhart
      David Bhart 10 months ago

      Obviously the actual temperature of the room your in changes all the time, but it generally just means "without any active heating/cooling", or in a more scientific sense, refers to "standard ambient conditions" which is marked at 25 degrees Celsius (and one atmosphere of pressure) for the purpose of more accurately comparing things that would be affected by these such as rates of chemical reactions.


    • Fidgetelftree
      Fidgetelftree 10 months ago

      Alexandra Mallory I think 'room temperature' is just the temperature most people are comfortable at. Not too hot, but not too cold either.


  • SquareWaveHeaven
    SquareWaveHeaven 10 months ago +1

    I always thought our thermal perception was just a side effect of touch. Being hot our cold is just those molecules vibrating (or slacking on the whole vibration gig) and stimulating our touch sense at a certain frequency. I realise now that's probably wrong or at least inaccurate.

    • Alexi Leclerc
      Alexi Leclerc 10 months ago

      we can't really detect hot or cold but rather heat in the sense of the transfer of thermal energy through our skin in one direction or the other. this causes glass, the stronger conductor, to feel colder than plastic to the touch when they are both at room tempurature.

    The reason that woman without a cerebellum can move relatively fine is because the acutal movement plan is made in the frontal lobe, then gets check up for the right muscles to be used in the pre central gyrus. Then goes to the cerebellum that does a check up if it is okay or not and adjust where nescesary. Movement is done but while doing it gives that info, propriorcepsis, back to the cortex AND the cerebellum. The cerebellum adjust the movement while performing that movement. See it like a fine tuning machine.

    • David Bhart
      David Bhart 10 months ago

      How so? Both use very different systems biologically and aren't really related, which is why people with certain nervous disorders may be able to sense touch but not temperature and vice versa. Plus you don't actually detect "temperature" as such, you detect temperature change, so things feel warmer or cooler relative to your own bodies heat, and hence give/take energy at different rates from your cells.


    • Lily Worst
      Lily Worst 10 months ago

      As defined in popular ideology, it would be, but scientists think of touch as sensing pressure, not heat.

    how about social senses like empathy, sympathy, sense of humor, intuition, sense of leadership, sense of identity, sense of social connectivity, extra-sensory perception etc. and inner senses like sense of hunger, sense of inner movement and pain or heat, sense of wanting to poop, sense of wanting to pee, sense of consciousness, sense of knowing we exist and be............. i know they are not traditional senses but they make us sense ourselves inside and other people outside in another way around than just seeing, hearing, tasting, smelling, feeling, having balance, knowing position in space, and responding to heat changes....... hope they'll be somehow included in the set of 8 senses..... we experience all of them, and we use them to navigate our world too, as well us to be aware of our surrounding and our inner bodies. :)
