I recently saw a comic book character (one in a long line of similar characters) who has a transparent dome for a cranium, exposing her brain beneath. As per the course for such fashion, she’s of course completely lacking dura mater, to better serve the aesthetic function.
Now, musing over the possible medical complications of having your brain exposed in such a fashion, the question occurred to me: can brain tissue get sunburned? Assuming the skull dome didn’t provide sufficient protection.
Now, I’m not a medical expert, but I’m of the understanding that a “sunburn” is simply the result of excessive ultraviolet radiation exposure. And thus, any living tissue would be susceptible to the same.
But I don’t technically know for sure, so I figure I should ask. Although I doubt that anyone here has any kind of firsthand or scientific experience in exposing human innards to excessive sunlight. (Or at least I kinda hope not)
So, stupid, silly, gross question, with a seemingly obvious answer, but I’d like to check with the experts to be sure. Can anyone enlighten my mind—very non-literally, hopefully?
I think that’s the case, and further, the purpose of pigmentation in your skin is to soak up the UV light with relatively little damage. So exposing a part of your body with no pigmentation to the sun would be disastrous.
A while back, there was a fad of “perenium tanning”, where you drop trow, bend over, and let the sun shine where it typically doesn’t. This area has little pigmentation and is not intended to be exposed to the sun, so this is a really bad idea.
Of course! Once Elon Musk’s Neuralink takes off, the next logical step is to add RGB lights to the brain inserts. Not only will it make you a “pro gamer”, it will provide all the benefits of brain tanning without the harmful UV lights!
Here, we developed a novel method for creating a lesion on the cortical surface via 365 nm ultraviolet (UV) irradiation without breaking the dura mater.
I then also found this article, that is about sunlight and heat radiation. That isn’t the same thing, but it demonstrates that sunlight exposure can cause cognitive issues–and that’s with the skin and skull in the way.
Acute exposure did not affect any performance measures, whereas prolonged exposure of the head and neck provoked an elevation of the core temperature by 1 °C and significant impairments of cognitively dominated and motor task performances.
