There are plenty of DIY scientific experiments you may put to the test , without needing so much as a lab protocol . Not all of them are just kitchen alchemy , though . In fact , here ’s a foreign experiment a neuroscientist give us to try out right now , on yourself .
In response toour query about the upright at - habitation scientific demonstrationsyou can do , commenter and neuroscientistResidentPonyshared this queer little trick that your brain plays on itself .

How do you do it and , more importantly , what on earth just happened to you ? Read on to find out :
Intro
well-disposed neighborhood neuroscientist chime in with my favored experiment , and you do n’t even need to be at rest home ; you ’ll just require a mirror .

Did you bang that the mediocre person go blind several times each second ? And that your mentality is lying to you ?
One Weird Trick …
Here ’s how to gather evidence that your brain ca n’t be trusted . Look into a mirror . Gaze deeply at your own eyes , admire your pretty irises . Focus on one optic . Then tack to the other . Then back . Read this in the vox of the Old Spice guy , but do it . coup d’oeil back and forth between your own middle .
And … what the hell ? ! You ’ll experience your eyeballs moving in their sockets , and you ’ll decidedly shift focus , but you wo n’t be aware of anything in the centre . There ’s no blurry image of the bridgework of your nose smeared by speeding . You just retick - tock between focal points .
The eye are doing their job just fine , thanks . But orb have a flaw ; for tightness and efficiency there ’s really only a small spot on the retina which turn over that excellent resolution patent by Apple . It ’s call the fovea and it is lilliputian , able to note only around 2 degrees of visual field . The rest of the retina is just fill up in background information , the fovea allow shrewd item and rich vividness .
Explanation , Explication , and Expiation ( for your eye )
So we cheat . When we attend at stuff and nonsense , our eye flick around to points of interest in a bent of very dissolute bm called saccade . There ’s a lot of meaning packed into that ; we ’ve get some awful algorithms for picking the best points to try out , and for plan this superspeed movement , and we ’ve come coprocessing circuitry for scanning clobber that is important to us , such as cheek .
That ’s right , I hold a high speed CPU for your look .
( icon via Wikipedia ; tracks indicate saccade social movement when viewing a human face . )
Also there are different types of saccades , and some of them go bad in certain disease states and can be used as a diagnostic tool .
Here ’s what happened in that mirror . The retina continue to mail information but the eye was move so the double would be smudge if we bothered to process it . But it ’s not specially useful information , since a. it ’s blurred and b. it was pick up after leaving a item of interestingness and en route to another point of interest .
So your mental capacity pretty much toss away it . * And then blot out the evidence so you do n’t ever even realize that it ’s chucking it out .
- It ’s utilitarian for some stuff , include error - checking and feedback for saccading , but it ’s mostly oppress from cognizance .
find anything strange when you tried it , perhaps something not unfamiliar to the videogame fans out there ? There ’s an explanation for that too :

There were a few … I dunno what you ’d call them … frames ? Where on top of not seeing my eyes move , the image of my eyes / face were n’t moving at all . The still image of my face was present while my eyes moved , fundamentally .

That verbal description vocalize a peck like a phenomenon which often come up in relation to saccades . Can I hazard a guesswork that this only occurred after you were well into the put-on , possibly while switching very speedily ?
Because your experience sound very similar to “ chronostasis ; ” gamers know it as “ fall back . ”
It ’s another artifact of perception where a stimulus lingers for longer than its actual observation time .
