View Full Version : The Blinspot
gendanken 01-11-04, 08:28 PM You people remember those fleamarket puzzle books with the hypercube that keeps flipping back and forth in your brain? and the old hag that depnding on how your brain receives it flips back and forth from a witch to a pretty maid with a feather in her hat?
There's a trick to finding your blindspot in there as well. You draw a circle or some other object and next to it inches apart something else, like a square or some panties. You close your right eye and keep your left on the circle about a foot away from your face. Now you move it slowly towards your face until the object next to the circle disappears.
Of course, it disappears- but the space 'fills in' with the background. If the background is green with red dots the space fills in with green and red dots as if nothing is there blocking it. I ran a black bar down the object that's supposed to fall on my blinspot and disappear- and the black bar continues gapless.
Why isn't there a gaping hole of nothing when the blindspot hits it? How does the brain know to fill it? Here's the amazing part- if that black bar is half black and half white, when the object disappers the space missing is a mesh of the two colors- gray! Try it.
How does the brain know?
Mephura 01-11-04, 08:43 PM The answer is easy if you ask the right question.
How would you see 'nothing'?
You have to have something there, so since the object in question can't be seen, the hole is filled in with the background.
This whole experiment only works because you have one eye covered though.
with both eyes, you have a stereo-optic effect, wich not only allows you to perceive depth, but also allows your brain to read from one eye what is in the blind spot of the other.
So how does the brain know what? It simply does what it does.
It fills in the background because you have covered the other eye and you can't see 'nothing'. The background gray effect is just a blending of the two. More or less, that is what happens the entire time with the experiment.
The brain just kinda averages out what is in the rest of the image.

But isn't it fucking amazing though? You can so tell I'm into brains now.
Yes and no. You gave me a simple answer, and it doesn't do the brain justice. Reminds me of how doctors try explaining away phantom limb....."its cautrized nerve bundles on the end of the stump still registering pain to the brain. Dip it in water- it will go away. No biggie". Not so.
The brain has mapped out your whole body on its neocortex and when something is missing there's reason to believe adjacent sections spill over onto the section no longer in use- which is why patients with no arm feel you touching that arm they don't have when you run your hands down their cheek.
There's people like James Thurber that having gone partially blind the brain replaces these 'blind' cavities with all kinds of things-not just the background to 'average out' the whole image and its reported to be some of the most vivid, erotically colorful images imaginable to make up for what's missing. Its called Charles Bonnet syndrome.

Why does the brain do this? Boredom?
Mephura 01-11-04, 09:07 PM phantom limbs and bonnet syndrom aside the answer to the question posed is simply that you have you other eye covered.
Phantom limb: doesn't happen to everyone. It's not a constant. Different people, different brains, different responses.
The syndrome and limbs can't be easily explained because not enough is know about how the brain stores info, and how the pathways are formed. The whole thing is slightly chaotic.
gendanken 01-11-04, 09:23 PM Mephurio:

...and I think the answer is much more complicated than that. Eat me.
Phantom limb: doesn't happen to everyone. It's not a constant. Different people, different brains, different responses.
That is true....but when it does, more reason to believe the answer is not that 'cauterized nerves' bullshit.
And you're right about the brain being a chaotic mess of noise..........it'd had to be to explain and put up with those things Rotten, wouldn't you say?
Mephura 01-11-04, 09:32 PM think what you will my lady. the answer this time is pretty simple. Not everything has to be complicated. In this case, the simple answer is the correct one.
as for the rest, well, yes. One would think it would take chaos to appreaciate chaos...
and to breed it.
But isn't it fucking amazing though? You can so tell I'm into brains now.

"Well, after all, this is the age of the disposable tissue and the spooky poo. Blow your nose on a person, wad them, flush them away, reach for another, blow, wad, and flush again. All the spoodles riding everyone's coattails."
- from Bradbury's makebelieve world were books burn. Motag has just eavesdropped exactly why it is miseralbe wretches like you are the perfect expendibles, boo boo.
Or this one:
"The dandy rallies his forces and creates a unity for himself by the very violence of his refusal. Profligate.... he is coherent only as an actor. But an actor implies a public; the dandy can only play a part by setting himself up in oppsition. He can only be sure of his own exitence by finding it in the expression of other's faces. Other people are his mirror. A mirror that quickly becomes clouded, its true, since human capacity for attention is limited. It (spooky's mirror and his audiance) must be ceaselessly stimulated, spurred on by provocation. The dandy, therefore, is always compelled to astonish."
....astonish or latch on like a fucking parasite, whichever comes first. And the Dandy is nada, according to Camus, as soon as the stagelighs burn out, the music dies, and the people go home where he's left to play with the most boring pile of human waste that is him. Now where *would* you be with no audiance, spooky?
(quietly sitting on spooky............). Now!
Mephurio:

Yes, but you said it only works becuase your other eye is closed.
You do know that its the blindspot that's filled in by the same eye looking at it, yes?
Consider this- people with migraines for brief periods in between headaches experience scotomas, or blindspots in their visual filed in *both* eyes. And these move when their eyes move, as if though it were painted on the cornea. Now, wherever these spots fall the patches 'missing' are filled in with the background- and these are large spots mind you. If one looked direclty at your head to them you'd literally look decapatated. What's fascinating is that in patients that have had strokes or macular degeneration leading to these spots- these patients can literally look at something disconnected ( like teh bar I told you I drew through the circle)- and literally see the bar pieces growing towards each other to make a whole bar! SHIT. YOU.NOT.
Its as if the brain loathes vaccums also, even at the cost of letting you see its secret played out in real time like these people seeing these bars growing in front of them do. The brain makes statistical guesstimates- filling in by assuming what comes next. Remember Wonka's study? His office? How everything was half and half? Its as if the brain would never allow you to see that room as reality. It'd fill in the rest (not saying it will, but work with me here- its a gedanken) So I'm thinking the world we see is only the images the brain has interpolated from assumptions by 'filling in" .
Sevi no sevi?
Bigblue:

I'm guessing they would. If they were like computers you'd get a pop up box saying "Pardon, but the OS does not detect a mouse or a driver. Please check to see what the problem is".
If they were like us you'd get a mouthful of how fucking odd it feels that his barking or your kiss on its snout felt like their phatom paw was being pulled.

screw the topic.
on second thoughts, bbh errs. actual feedback is not required.
if most humans report phantom stuff, it is mere stats that should indicate presence of same in another species. criteria will be similarity to us. the highest concordance should see the highest likelihood of phantom stuff
BigBlueHead 01-15-04, 08:35 AM Well, that's no help at all. How do you accord similarity, and does that mean that rats have, say, a 50% chance of having phantom limb pains? I don't know if probability is really enough here.

unscientific sure. similarity would be the possesion of a fairly complex nervous system. stuff like that can be quantified. rather than assume rats can, i'd pick a species with a greater physical likeness to us, perhaps a chimp
lets chop a limb off and place under observation 24/7. an unconscious attempt to pick with phantom limb proves its imagined existence.
tho rats might, i think unsophisticated neurals due to small size. could be a mistake. aint we supposed to be like pigs more than any other?

You more than others, but that's besided the point.
Surprisingly spooky here's hit on something- chimps with amputated limbs (those rescued from circus masters and rinky dink zoos and then brought to sanctuaries to recover) have been shown to pick up trays or objects requiring both hands set out by researchers as if though they had two hands.
Meaning: if you had only one hand or I tied that paw of yours behind your back spooky and told you to pick up my breakfast tray, you'd pick it up by the middle considering the limitations I've imposed on you that you're conscious of.
If you had both paws you'd aim to pick it up normally- both hands on both sides.
The idea is these chimps still think in terms of both hands despite missing one and so handle objects requiring both hands for support as if though they still had both.
Also- I've found why we love getting toes sucked.
BigBlueHead 01-16-04, 12:11 PM As far as the chimps are concerned that's a pretty serious accusation of stupidity; on the other hand I don't have any evidence that chimps are geniuses to begin with, so I guess that's not out of place.
I've seen a cat walk on a piece of paper that stuck out from the side of a table, thinking that it was solid ground, and fall when it put its weight down. Of course, long observation of animals in natural and artificial environments has taught me that animals are pretty embarrassingly stupid, so that didn't come as a surprise.
Maybe the chimp just doesn't know that it's easier to grip something in the middle when you only have one hand?

Muhahha......*corpselike grimace*
Gendanken just so happens to have a dog that loves sleeping under the living room table. She goes up to him, holds up a piece of old ham, demand that he jump and Voila- the little mook jumps up and hits his head on the table on cue. She'll let a minute pass until he falls asleep again, holds up another piece of ham, says jump and Voila- he does it again. She could do this all night.
Embarrassingly stupid indeed.
Maybe the chimp just doesn't know that it's easier to grip something in the middle when you only have one hand?
I would think so but the same thing happens in people with hemineglect- stroke patients that ignore the opposite side of the lobe that's damaged, I'm sure you've heard of them before. They literally act as if both sides are still functional. We could say its Freudian denial they cling to social-wise but the same thing happens when no one is looking (as in researchers watching from behind the looking glass).
Phantom limb patients act the same way- confronting obstocles with a mindset of having both arms and literally feeling the limb grasping the tray, the coffe cup, that table. A second's reflection later they realize the mistake and re-orient themselves. I say this happens in these monkeys as well.
......................and no one is even the tiniest bit curious about this?:

Lookyhere bucko- what you see before you is stuffed with shit she picked up in books, remember those? Theyr'e these paper things made with tree bark sewn together and shipped out worldwide by publishers.
If you'd like some scans ~to peruse~ I'm holding up an MEG pic of a 22 year old man named Tom Sorsoret who's lost his left arm in an accident. There's a Penfield map of the whole body mapped out on the pareital lobes and when you touch his cheek you see the left arm "section" of the map flare up on the screen. Touch his nose and he feels his fingers, he smiles and his phantom thumb flares up. I'm holding the pic up with my lips and you can't see it, and why? You spend all your godammned time trolling the internet.
Pardon, spooky, but I can't help you.
EDIT: its "sewn" not "sown"
BigBlueHead 01-16-04, 03:03 PM So what about the toes then?

No- never mind the imagery let's be real here: you're a cantankerous little liar and why? Wasn't it you long ago barking about not trolling my threads anymore with your rubbish? You really can't stand me............and I can't stand you. Yet the dandy in you insists on making my threads some kind of stage for your carping inanity.
Allways remember where the stars go when the stagelights burn out.
Bigblue:

Good! Finally, someone asked.......
There's a 1950's doctor named W. Penfield that anesthesized his patients and prodded their brains fully conscious. By doing so, he was able to pinpoint sensory data on the cortical mantle, an idea gets into his head, and behold! he maps out the human body image on the pareital lobes.
It just so happens to be that the area portioned out to receive messages from the feet is exactly adjacent to the small area dedicated to the genitals. And so when either of these areas are stimulated, the same feeling tingles in between them. Shit thou not.
A look:
Penfield homunculus
http://www.23nlpeople.com/sensory_motor_cortex.htm
And here's the funniest bit- this book I've got here talks about a man who's lost his leg some months ago below his knee. He calls the doctor up to ask about the strange things that happen during intercourse, the doctor tells him something about the Penfileld homunculus and the man replies:
"All that's fine doctor- but you still don't understand. You see, I actually experience my orgasm in my foot. And therefore its much bigger than it used to be because its no longer confined to my genitals"
And so.................gendanken here's thinking if you men really *would* like to be hung like a horse and feel like one, the surest means is chopping your foot off. I'd do it for you myself.
Allright you buttfucking ingrate- if I had the means I SWEAR to you you'd be in a wheelchair with your balls tied up in braids. No- never mind the imagery let's be real here: you're a cantankerous little liar and why? Wasn't it you long ago barking about not trolling my threads anymore with your rubbish?

Now- ain't it grand to find out just why toesucking is mindbending? Freud had it that the foot was phallic, hence the fetish. But why not some other elgongated body part? A nose fetish or an arm one?
BigBlueHead 01-20-04, 03:05 PM I cannot rest from travel; I will drink
life to the lees. All times I have enjoy'd
greatly, have suffer'd greatly, both with those
that loved me, and alone; on shore, and when
thro' scudding drifts the rainy Hyades
vext the dim sea. I am become a name;
for always roaming with a hungry heart
I am a part of all that I have met;
yet all experience is an arch wherethro'
gleams that untravell'd world whose margin fades
for ever and for ever when I move.
Come, my friends, 't is not too late to seek a newer world.
push off, and sitting well in order smite
the sounding furrows; for my purpose holds
to sail beyond the sunset, and the baths
of all the western stars, until I die.
We are not now that strength which in old days
moved earth and heaven, that which we are, we are,--
one equal temper of heroic hearts,
made weak by time and fate, but strong in will
to strive, to seek, to find, and not to yield.
- UIysses, Alfred Tennyson
So long Spooky. Sail the web forevermore! Rest assured, Wanderer will... sit around... and not really... do much.
Ahem.
Freud thought everything was phallic. It was kind of annoying actually. Although I wonder what he'd make of a Playstation controller. All those different buttons, press here, press there, get your hands all over it... anyway.
I don't think Our Man in Vienna really had much of a line on neurophysiology, so I'll leave that topic alone.
