Neuroplasticity is great, though it basically means we spend our younger years calibrating to our body, building proprioception. What's especially interesting about it, however, is that it technically means we can develop a sensitivity to signals that has nothing to do with our current senses. There's probably input that makes more sense than others, and there's obvious issues with trying to feed it directly to the brain, or making custom inputs, but any sense is just a set of signals, and any set of signals can be interpreted. Some of those interpretations are more hardwired than others, but the fact that not all of them are hardwired will make it interesting to see how the field develops.
Yes, and this is the basis for sensory substitution or sensory compensation. Other senses can "spill over" into other domains; e.g. this TED talk from a guy with pure colorblindness, but was able to perceive colors by hearing different tones. Or, how blind people can recruit their seemingly unused visual cortices for other processing, like hearing or touch.
THAT'S not the full experiment, though! The experiment terminates when the researcher takes out a HAMMER AND SMASHES THE FAKE HAND!! Totally freaking out the subject!
The human brain is excellent at adapting to different types of realities. That's why some dreams seems so real. It is only as real as your brain tells you it is :)
Mirk Jerken i know this sound crazy but i had a dream that my hand was burning and my skin layer buy layer piealing of and i could feel it all the burning and piealing off is that possible? I mean i know its possible because i was felling it . Tho my hand in my dream was not on fire it was just i dont know its weird.
A dream can’t make you feel pain If you felt pain, which means the brain puts the “pain stimulus” from the real world into your dreams making it seems like it was the dream that was making you feel pain
Really interesting Learning - The Rubber Hand Experiment demonstrates the brain's capacity for multisensory integration and its ability to adapt quickly to new sensory information, blurring the boundaries between self and non-self. It highlights the importance of sensory input in shaping our body image and our perception of self.
I pet furries in VR and they believe they have real fur that im really rustling and they are extremely cuddly and ticklish. verbalizing squeelz it makes me think the chick im talking to is.... actually cute
that was a very old experiment reproduced, similar to that where people who lost a limb would have their remaining arm in a box with a mirror to get rid of phantom pain, part of psychology but sure feels real,
This was so creepy and awkward I almost thought it was a parody with the huge goofy smile the brusher wore and the host sitring right there to observe a foot away and then to describe how a brush to the hand feels
I don't get the concept... If you touch both hands of course you feel a touch. But what should lead me then to the assumption that the rubber hand is mine?
I'm sorry I don't understand why this is sensational. His finger is attached to an artificial look-alike. They decieve is brain into thinking it is moving the artificial hand... but it is. His brain is entirely responsible for moving the artificial hand albeit that it is not visually aware of the connection. Did I miss something? You get a similar feeling of going in between two extremes if you lay on your arm long enough and get pins and needles, that in fact you are not responsible for actuating this machinery, then as blood returns to the nerves the idea of agency is restored. I think I'm missing something.
Perhaps that is what I missed. That there is a feedback effect to sensation from the central onto the peripheral. But if that were the case or the intended effect, why don't they stimulate only the fake hand instead of both at the same time after establishing that link? I still think this video is going way over the top on detailing the contours of an exposition which shows something we are all already familiar with.
He did everything that he did to the real hand he did to the fake, but his brain could only see the fake. His brain makes the connection that the fake hand is his, so when he hurts the fake hand his brain is shocked, thinking it is his
They probably didn't smash it with a hammer because it was attached to his finger and he might hurt himself or break the contraption by yanking his hand out.
Oh man... no hammer or knife to the rubber hand to demonstrate that the brain will actually make you FEEL the pain in the hand that isn't attached to your body? I am dissapoint!
What if he moved more than his finger ?the illusion would be over..come on it's a show ..obviously that's why they are bringing a well known actor for it
