We don't have to tell you how amazing your brain is. Even if you're the dumbest guy on the block, your mind is spectacular. But there's a dark side to this complicated organ of brilliance, because when it goes wrong, things get weird. Here are five more ways your brain can suddenly turn the world into a bizarre carnival of the absurd.
5Attack of the Jibber Jabbers
Remember that scene in Bruce Almighty when Jim Carrey uses his God powers to turn Steve Carell's newscast into a nonsensical disaster?
You know the one.
Well, what's hilarious in a movie is incredibly creepy in real life, where it's called receptive aphasia. These patients (usually people recovering from a stroke) speak with the same syntax, inflections and grammar they've always used, but the words coming out of their mouth holes are strings of incoherent gibberish. Also, both spoken and written language is gibberish to them. They'll look you right in the eye and give you one sentence that's normal, but the next will be nonsense. The results are really, really weird:
In that video, a woman with the condition attempts to answer some simple questions and perform a few tasks. She alternates between being able to answer with ease and sounding like a breakdown in an old school hip-hop album.
Again, if you didn't know English or turned off the sound, you'd think the lady was speaking normally. Everything about her body language, inflections and facial expressions indicate that she's perfectly comfortably engaged in conversation with her granddaughter about the good ol' days. She's not confused or frustrated or stumbling over words. It's not until you turn up the volume and hear the almost Tourette's-like sounds coming out of her mouth that you realize anything is wrong. People who've recovered from it say it was like their mouths just took off on their own -- they didn't know what they were about to say or understand what they were saying once it started.
So it joins schizophrenia and narcissism on the list of "mental illnesses that can help your political career."
The damage can come from head trauma, tumors, strokes or other illnesses that affect the auditory cortex of the brain. Strangely enough, there is one form of language that sufferers of this condition can process with no problem: song lyrics. We're not kidding. Song lyrics are processed by the other hemisphere of the brain. So, could you theoretically re-learn how to communicate with somebody by learning to talk to each other entirely in song lyrics? Has no one honestly ever tried that?
"Don't stop believin' you fill me up with this American pie, Mr. Mom."
4Motion Blindness Turns Everything into a Slideshow
Imagine standing at a busy street corner, waiting for the signal to walk across. But instead of seeing the blur of fast-moving cars, bikes and hipsters on unicycles, you only see cars standing still. Then you blink, and the cars and people and monkeys on stilts are further along, but are still frozen. Nothing moves. All is motionless. Are you dead? Is this Instagram heaven?
"OK, wait. I'm going to need you to describe everything that led up to this."
You actually have akinetopsia, otherwise known as motion blindness. Your eyes are fine, but lesions or traumatic damage to your visual cortex have left your brain unable to perceive anything moving. It's just a stuttering series of images, the way Crysis looked on most old PCs. So, watching sports would be nothing more than a series of sweat-drenched people manipulating themselves into stretched postures. Depending on the context, it would be impossible to know if you were watching wrestling or porn. Every time someone entered a room, it would feel like a poltergeist haunting. Walking in a crowd would require predicting the movement of everyone around you to avoid collisions.
And if you're running from the CIA, all you can do is blink really fast, like running in a strobe light.
Fortunately, the condition is so rare that doctors have only studied a handful of patients who've had it. But what we've learned is that it's the little things that frustrate the most. Like water. Imagine not being able to perceive the movement of liquid. One patient, "L.M.," couldn't pour herself a glass of water without it overflowing -- she couldn't see fluid rising to the top of the glass. Handwriting was an exercise in frustration, since she couldn't see her own hand making letters.
L.M. eventually trained herself to use sound cues to figure these things out (that is, the same way blind people know when to stop filling a glass, or when it's safe to cross the street). You can get used to anything, apparently.
Especially if your sound cues come from a person you hired to scream things like "STOP POURING WATER NOW!"
