How to evade near infrared spectroscopy brain imaging?

    Does anyone know how to evade having your brain imaged by near infrared spectroscopy? I believe it is a similar challenge to evading being imaged by infrared surveillance. However, in this case, the main goal is just to distort or scramble the infrared light being emitted by the head to prevent imaging. I tried a tin foil hat already, but that did not block the signal. Any thoughts? Maybe cold packs, space blankets not touching the skin...?

    EDIT: Here's a link to the Wikipedia page about functional near-infrared spectroscopy brain imaging. Functional near-infrared spectroscopy - Wikipedia

    I have found that a beer hat helps me evade a lot of things.......

    The brain does not emit light and even if it did, the skull, flesh and skin (and hair for those that have it) would block it.

    Not an issue.

    image. If you note, the emitters and receptors are shielded from ambient light by the black unless you have an apparatus similar to the one pictured, it isn't going to be an issue.
    ETA: actually, a tin foil hat would block the NIR light and its reflection.

    Thanks for this. In that case, I'm not sure if it's near-infrared spectroscopy. Another possibility is that it might be a portable SPECT scanner. Any ideas on how to block that? Or, does anyone know of any functional neuroimaging technique that can penetrate aluminum foil?

    My buddies at the lab are playing a prank on me, and they've really stumped me this time! They're brilliant physicists, and I am not, so I really don't know what to do. Please help me.

    To begin with you must have a brain to scan...

    Is this a serious suggestion? If so, why rare earth magnets?

    You do not know a lot about Photon Physics, I take it?

    Of course not, rare earth magnets are too expensive to waste on hair brains.
    How to evade a scan? EZ, don't let them put a helmet on you.

    No, I do not. Please "enlighten" me.

    Here's my primary question, now that I realize I don't even know what imaging technique my buddies are using: what kind of radiation could be used to perform functional neuroimaging in theory even if the person's head is covered in aluminum foil? To make things interesting, let's say no radioactive dyes or other tracers not normally found in the body would be used.

    Unless you are in the Giant Magnet Donut of an MRI Machine, or wearing a Beanie of some kind, You are safe from any external Imaging....

    Ground your foil beanie. Shunts the signal to ground better.

    You might try sticking with the Survival Monkey mission, it's safer than cranial exposure to strange emissions.

    Everyone knows that aluminum foil is useless. You need genuine tin foil or they can see right through it. You do know that Reynolds Aluminum is a secret government plot designed to keep genuine tim foil out of the hands of everyday people. I've heard so called "experts" say that audiophile grade zero oxygen copper or silver can be used as well, but they are just a bunch of kooks.

    @OdinTheDO your friends are asshats and screwing with you. I used to work in an office full of PhD's and later M.D.'s. They are every bit as gullible as anyone else and tend to be just as ignorant outside their field of expertise so don't let them get to you.

    Are you joking about the tin foil part?

    I agree that is the most likely interpretation based on what I've told you. The truth is much more complicated than that. I'm sure exactly of how they're doing it, but I am very sure at this point based on many, many experiences that a group of people are using some kind of brain computer interface or functional neuroimaging technique to "read" the words in the thoughts I'm thinking. They refuse to stop doing it no matter what I do. I realize this makes me sound mentally ill, but I'm not. If you can help me figure out how to cut off their signal (which I would be able to tell by inference in several different ways), I will tell you what's really going on. All I'll say for now to hopefully pique your interest is that it's not the government doing it for nefarious purposes. It's people in Silicon Valley and academia doing it for purposes that sound good on paper, but in practice are extremely problematic.

    The first problem is figuring out the technique. The company associated with one of the people involved was recently linked to a brain-computer interface published about in this paper: The “sewing machine” for minimally invasive neural recording . This person's company also has access to satellites. I think they can still receive signals through aluminum foil.

    I apologize for how crazy this makes me sound. Please humor me.
