Heighten Your Senses By Simulating Blindness!

Daredevil was actually a pretty cool, legit comic book, until the Affleck Attack happened.

But the idea of blindness enhancing other senses is just fiction... isn't it?

Hey gang, Trace here for DNews! Thanks for tuning in.

There's a common thing in superhero and fantasy media... if one sense is lost, the others

get better to compensate. Do senses really DO that? The research says yes! The brain

is a glutton for input, so if you restrict the input channels it freaks out. Sensory

deprivation tanks are this in a nutshell. Research from the Journal of Nervous and Mental

Disease found, when people were placed in a sensory deprivation room, the brain couldn't

tell if the thoughts and images it was creating were inside the head, or outside the body.

When deprived of input the volunteers would experience visual hallucinations, paranoia

and a depressed mood -- all this, with less than 15 MINUTES of loss of input.

So, if that's what happens with ALL the senses dulled, what about with just one? Studies

HAVE shown blind people experience a higher sound placement ability, and increased sense

of touch. This has to do with the brain literally REFORMING to take resources from the missing

sense. A study in the Journal of Neuroscience used fMRIs to scan the brains of people who

were born deaf. They found their senses of sight and touch were altered... and they found

a boost in the understanding bimodal stimuli. Bimodal stimuli boosts are commonly seen in

those who are bilingual -- they have a lot more crosstalk between their senses. This

means people born deaf SEE the world differently than a fully sensed person!

Now, knowing ALL that -- does someone who BECOMES blind gain sense-power? A study that

came out last week says FOR SHIZZLE. Researched published in the journal Neuron found when

fully sensed mice had blindness simulated for as little as one week -- their hearing

was boosted. The researchers said this has to do with how the senses work together. Kind

of like in a movie, if what you're seeing doesn't match what you're hearing -- you'd

get messed up. Your vision is supremely tied to what you're hearing. Their experiments

found sight helps us hear softer sounds, and have better pitch! Because of that, your sight

can help work with your hearing to help discern talking or familiar music in a loud environment.

If you take what you're seeing AWAY however, your hearing has to do it alone -- and it

flips switches in your brain called thalamocortical inputs. This lets the auditory information

borrow some of the processing power of the visual center. It seems to me this is kind

of like Daredevil's power! He's using his VISUAL center to understand the perceived

SOUND. This has been documented in others too, people who are blind yet can navigate

an unfamiliar room, and even ride a bike.

The switches they're talking about, are normally not used in adults -- but in a week of blindness?

BAM. Switched. Very cool. They also found when they removed the blindness, the switches

went back to normal -- so it's reversible. Super cool.

Would you go blind for a week, for science? Think of all the things you could hear!! Come

tell us down below, we read the comments and love to chat. Thanks for watching DNews, hear

you later!
