This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

I remember this picture from biology class but there was a penis hanging off the side 🤔

[–] jewbacca117@lemmy.world 6 points 8 months ago

tell me more about this brain penis

[–] JeezNutz@lemmy.ml 5 points 8 months ago

I was disappointed when I realised there was no genitals 😥

No, but the closeness in orientation explains why foot rubs are erotic. Stimulation of the foot and toe region of the brain will affect the neighboring genital region causing arousal.

Would that not in turn explain the foot thing

[–] Deadful@lemmy.world 2 points 8 months ago* (last edited 8 months ago) (1 children)

I don't see how because a foot fetish is an attraction to someone else's feet, as in "feet that don't have a neighboring nerve connected to the same part of the brain that controls said foot pervert's dong."

This is actually science related to the electrical impedances of nerve and brain tissue.

The connection between foot nerve stimulation and genital stimulation is a physical one that can (and has) been measured and reproduced. This response is nearly universal and affects men and women, unlike a foot fetish.

I think a better explanation for the fetish is that feet are a part of the body that is often covered and seen as generally dirty, giving it a taboo allure other non-sexual parts of the body don't usually have, but that's less neurology and more just my opinion. Lol

Edit: added the usually

I mean, if your partner gets turned on when you touch their feet I'd expect that to make you feel something too. But I do think your theory is compelling as well.

I found it on the wiki pages for phantom pain, what's this about food fetishes though?

[–] SeaJ@lemm.ee 4 points 8 months ago (1 children)

Toes and feet are next to genitals.

[–] JeezNutz@lemmy.ml -1 points 8 months ago* (last edited 8 months ago) (1 children)

Hmmm yes. Would that mean you're attracted to other peoples feet or attracted to your own sexual feet stuff 🤔

[–] burgersc12@mander.xyz 4 points 8 months ago (1 children)

Bros never heard of a foot fetish. Ask a woman her stories about creepy feet guys, most will have at least one I bet.

[–] Sylvartas@lemmy.world 2 points 8 months ago

Nah, the proper way to enlighten someone about the existence of foot fetishes is to tell them "just look up wikifeet bro"

[–] Deadful@lemmy.world 11 points 8 months ago (1 children)

I'm an EEG/Sleep technologist and an older coworker just gifted me an ancient book with a similar image inside that may have the genitals. I'll check when I'm back in my office and upload if applicable. 👍🧠🍆

[–] JeezNutz@lemmy.ml 1 points 8 months ago (1 children)

Yes please!

[–] Deadful@lemmy.world 3 points 8 months ago* (last edited 8 months ago) (1 children)

Aw man. No dice. For some reason I thought I remembered seeing brain dicks, but I was wrong.

This painting doesn't even mention genitals!

The book is from 1953, so maybe that's why.

Edit: wasn't able to share photo before but I just took a new one and it worked.

Foot, toes and genitals related?!

[–] SacralPlexus@lemmy.world 5 points 8 months ago

Feet are a very common sexual fetish and this observation you made has been theorized to partly be responsible for that. Maybe those nerves from feet/genitals sometimes talk to each other.

[–] intensely_human@lemm.ee 2 points 8 months ago

Foot bone’s connected to the dick bone

[–] Kolanaki@yiffit.net 8 points 8 months ago* (last edited 8 months ago)

This is how creatures "look" in Dwarf Fortress to the game itself, since they're only programmed to have parts; but there is nothing that distinguishes where the parts actually... Are?

Someone made a mod that visually represents every monster in the game the way the program is connecting the parts together and it's pretty fucking funny. It's also how you can do absurb things like biting something's foot while you're stuck in a headlock in their armpit.

Does anybody else ever feel like this, physically? Like right as they are drifting off to sleep, or coming out of a dream? Or during a fever? I swear- I have felt like my hands and tongue and mouth are HUGE many, many times.

[–] Imgonnatrythis@sh.itjust.works 4 points 8 months ago

Don't think the butt is supposed to be labeled "neck"

Ngl I have no idea what I'm looking at here

[–] SacralPlexus@lemmy.world 4 points 8 months ago

It’s a map of the surface of one part of the brain. Imagine a Star Trek scanning beam going across your head from right to left, about where your ears are. This is a picture of half of that part of the brain (the other part is a left/right mirror image of this picture).

So the cells along the surface of the brain here are connected to the sensory nerves in your body and this is a map showing which body parts are where. So if you move to the top of the brain it is the area where you feel sensation from your abdomen. Go further down the side and you get to arms and then hands, then face. Notice that sensitive areas of your body are much bigger (hands, face) because a lot more brain tissue is devoted to those areas.

Handy wiring diagram.

Do they ever get plugged into the wrong spot?
