i was watching cops and the cops said that you couldnt cross your eyes while you are stoned and i would like to know if this is true or false.;j
say false. I would
crosses eyes
Yes, it is false. Cops are generally completely ignorant to the real effects of cannabis. I won’t even speak of other entheogens.
OK, eyes are crossed.
Somebody hand me a doobie.
Good old, reliable television. It restores my faith in, um,…hey! It’s not true!
adds to list of experiments to try
That’s a frat-boy bar bet. The usual methodology is to brazenly insist that it can’t be done. When the mark easily does it, frat-boy insists they didn’t really, and drags the mark off to the can to demonstrate in front of a mirror.
The idea is that because the victim can’t actually see themselves crossing their eyes, frat-boy somehow wins the bet.
This tells me that your cop probably picked up this bit of useful knowledge while getting high in the company of some wag with a frat-boy mentality, and also that he seems to have cultivated a level of ignorance and gullibility far in excess of that required for his buddy to collect the bet, since I imagine that most folks who are stupid enough to fall for such an embarrassing ruse when they’re drunk or high can at least make out that they’ve been duped when sobriety returns.
Doctors? Why couldn’t some drug effect the Cranial Nerves in such a way that crossing the eyes was very difficult or impossible? Many drugs, even alcohol screw up CN VI to the point where smooth lateral pursuit is impossible.
Im curious now. Couldn’t some drug prevent one from crossing his eyes?
I would doubt that any chemicalwould produce such a specific deficit. If you can’t stand up, or breath or hear, you can’t cross you eyes, sure, but it would be sheer luck if a chemical happened to affect only one set of motor neurons or had that one isolated effect on a neural nucleus.
More importantly, coordinating the direction of your eyes for binocular vision at varying distances and orientaions is a delicate act. it’s not that you wouldn’t be able to cross your eyes, it’s that you’d never quite get them uncrossed. Diplopia or double vision caused by a misalignment of the two eyes can happen in quite a few conditions. It’s how the oculomotor system breaks down.
Crossing your eyes is a trick, but it’s hardly as delicate a trick as precisely aligning both your eyes for normal vision. If they cross at all, you’re done, even tif they are a few degrees off, unlike normal binocular vision. Consciously misaligning your eyes, requires overcoming a hard-wired instinct and a lifetime of useful experience since infancy - but it’s like missing a target, you can’t do it “wrong”.
Bear_Nenno suggested a condition where smooth lateral pursuit is impossible. This kind of effect is usually cause by a lesion (which can be caused chemically) not a transient chemical effect. That’s because (AFAIK) there is nothing particularly special, neurochemically, about the medial rectus, CN III (not VI) and the various coordinating nuclei - maybe there is, but I don’t know about it, and it’d be total luck.
you can cross your eyes just fine while stoned, I have plenty of friends who can do it just fine. the only thing cops (at least those with a clue) are looking for when they tell you to follow the pen or whatever is for tracking, when you are messed up on most drugs your ability to smoothly track moving objects close to your face is prety seriously impared. its a strong clue that you may be on something and that combined with whatever other observations they have made determines whether or not the bust you. I suspect that most cops using this line are trying to get your stoned and thus stupid ass from saying something incriminating. dont you people watch Law and Order?
Sorry, Bear Nenno. I just realized I misread your remark.
To make up for that, I’ll give you a better answer. Four of the six muscles that control the eyeball are controlled by the same nerve (CN III) it would be difficult to image a chemical that knocked out only the functions of the medial rectus (the muscle that pulls your eyeball to the midline) and not the superior rectus and inferior rectus (which move your eye up and down) inferior oblque (which rotates and helps elevate your gaze) or even the levator palpebrae superioris (which holds your eyelid open)
CN VI, by contrast, only innervates the lateral rectus (which moves your gaze laterally) That’s all it does. But don’t call it lazy - CN IV only innervates the superior oblique (which helps rotate and lower your gaze.) Clearly it would be easier to affect these nerves (or structures they pass or the muscles they innervate) in isolation. For example, botulism tends to affect CN VI first.
thats stupid ass TO SAY somthing incriminating…really it is!
