My favorite – this is to some degree my interpretation though! – my favorite is the default mode network, a kind of constellation of brain activity.
It’s called the default mode network because they found it through magnetic resonance imaging or something like this, and this activity pattern was the first pattern they saw!… A-ha! This is the default mode network! The default! The default mode! Yes!… the activity pattern in the brain of a human who has been persuaded to go into a very tight-fitting tube and is there all alone and it’s not pleasant.
The default mode is activated during introspection and social isolation and among the things it does is generate the sensation of being something which is distinctly not part of the rest of the world.
- ulbu 2y agothis is so interesting. it’s not the first nor the last time wish that communities would not refrain from changing terminology. fitness is as important as accuracy and we shouldn’t be wary of dropping such inaccuracies, especially when they bring such strong connotations.
- PaulHoule 2y agoFor one thing the technology in an MRI based on a phenomenon known as nuclear magnetic resonance https://en.wikipedia.org/wiki/Nuclear_magnetic_resonance https://en.wikipedia.org/wiki/Nuclear_magnetic_resonance they dropped the "nuclear" bit because it is scary, it doesn't involve any ionizing radiation. It is all about making the nucleus wobble but not about splitting atoms. I have fond memories of doing NMR experiments in senior labs as a physics major.
- alyandon 2y agoI'm not one to typically have strong fear/anxiety responses in situations that aren't actually dangerous. However, I felt extremely uncomfortable being partially inserted into an MRI tube for a lower body scan. I couldn't imagine being shoved head first into that thing without being heavily sedated or completely knocked out.
- kstrauser 2y agoI had a head MRI and my main anxiety involved praying to any powers that be that my tooth crown was truly non magnetic.
- Loughla 2y agoSweet Lord, that is a white hot fear. When you remember the really old metal filling you have right before the machine kicks on.
- kstrauser 2y agoThe thought crossed my mind, to be sure! I talked about all that with the techs beforehand. "Are you sure this isn't going to yank my teeth out?" "Pretty sure. Now stop moving around."
- TeMPOraL 2y agoThey put metal detectors even in schools these days, can't they put one before the MRI lab?
- lawlessone 2y agoI have permanent braces attached to the back of my teeth. I know they're magnetic, i can feel a slight pull if i hold a magnet close to them. I don't know what i'll do if i ever need an MRI, otherwise i'd probably just find it cozy..
- kstrauser 2y agoI have a simple hiatal hernia. One of the treatment options is to basically put a weighted band around your esophagus above the stomach so that the weight holds everything downward so your stomach doesn't get pulled up through the hernia. I imagined being in a car accident or some other situation where I'm nonresponsive, the doctor ordering an MRI, and me re-enacting the scene from Alien. Nah, I'll take my chances with the hernia, thanks.
- dv_dt 2y agoSo this activity pattern could actually be the claustrophobia mode network?
- TeMPOraL 2y agoOr "questioning the life decisions that led to finding myself in this situation" mode network?
