It’s a transverse section so it’s not really ‘top down’ or ‘bottom up’. It’s a thin slice where the densities of the tissue is calculated by sending through X-rays from around the body and measuring how much gets trough from each angle and then letting a computer do some fancy math.

TBF this doesn’t have anything to do with sexism, it’s just general incompetence. Listening to the lungs with a stethoscope would have been enough to notice that something was very wrong.

There’s this docu series on netflix (unnatural selection) about genetic engineering in general but also about some people (with and without science background) who believe that anyone should be able to do genetic engineering at home (Josiah Zayner is one of them, i believe he still sells lab equipment and reagents for anyone who want to do some DIY bio-engineering). They also follow this guy who stopped taking his HIV meds and started using some kind of antibody that was developed by some shady company (it didn’t work and guess what; not a single physician was involved). I believe one of these shady guys was found dead in a sensory deprivation pod with ketamine in his blood.

I think I understand what you’re saying. I have a medical background as well and I guess clinicians mostly use the results of (neuro)science in their work. Neuroscience can seem as one big field but many labs do exclusively mol. biology work, others work exclusively on developing theories/models, others focus on functional imaging. Even within the computational field, there are multiple subfields. These people often have very different backgrounds so not every neuroscientists will be able to do wet lab stuff, computational work is often done by physicists, engineers or mathematicians, … Everything is so specialised and crossing over from wet lab stuff (near zero math/physics experience) to computational work is extremely difficult so scientists often need to choose a field to focus on early in their career. It’s not as simple as running some simulations or doing some modelling for a specific question. For example some neuroscientists with a psychology background do functional imaging studies (fMRI, EEG, …) but if they would have a certain hypothesis that would require wet lab stuff, they would probably not have the knowledge or tools to do this. There are very few neuroscientists who know their way around all these different fields.

I’m more interested in the ‘fundamental' questions in neuroscience, how information is represented and processed, how consciousness can be defined and studied, how memory works, … These topics can be approached in multiple ways. For example memory requires both knowledge of the biochemical/cellular pathways and the mathematical/computational aspects so wet lab skills and computational skills could both be valuable. I’m wondering which field will be most likely to come up with some groundbreaking discovery.

What do you think are the most promising fields of neuroscience for the next +/- 20 years?

I feel like computational neuroscience might develop some breakthroughs, i feel like there’s only so much we can conclude from biochemical / mol. biological research alone so for fundamental insights, we’ll need mathematical/physical models as well. Functional imaging also seems like an interesting field.

A very readable article about chronic depression and the serotonin hypothesis.

Psychiatry seems like a very interesting field for neuroscience since there's not really any psychiatric disease that is understood today. Lots of room for progress I guess.

White bread, cheese (at least not the one on burgers) and red meat aren’t exactly known as healthy foods. Definitely not in the proportions of a burger. Even more definitely not when you boil the meat in oil (often together with the onions).

Yeah I get it. The companies developing these drugs or funding the research probably don’t care about fundamental knowledge. Even in pure academia people would probably rather have some publishable results than actual insight in a disease.

If they did, there could’ve been some psychiatric diseases that were actually understood as well.

I don't think there's anything fundamentally wrong with eugenics. Screening for genetic diseases before birth is eugenics, selecting the best embryos for ivf is eugenics. Believing that people with severe genetic disabilities should be counseled before conceiving is eugenics as well.

The issue is the way it's done and the reason for it.

I’m not sure how many people know about these videos but I think they’re pretty cool. I’ve been watching some of them and for anyone with a basic knowledge of neuroscience and math, they’re pretty interesting and accessible.

The visuals are also amazing, a bit like the 3blue1brown videos. Just thought i’d share.

Hi everyone!

I’ve set up this community for anyone who’s interested in neuroscience.

Anyone is welcome: students, researchers, enthousiasts, …

Not sure to be honest but i’m guessing that enough would be left and that the air would resorb and new CSF would be made in the ventricles.

Apparently this was done because air captures less X-rays than CSF and thus creates more contrast with brain tissue compared to the cerebrospinal fluid.

Unfortunately this was pretty painful and uncomfortable.

Weird, it works for me. Maybe this link works: https://lemmy.world/c/neuro

For anyone interested in neuroscience: we’re trying to create a neuroscience community over at: !neuro@lemmy.world

One of my math teachers explained it exactly like this. ‘For the people who know how to program: this is the same as using a for loop’.

A big issue with the dolphins is that you can't just release them. I agree that they should be phased out but dolphins can still more or less be kept happy and stimulated if done well. (still not the same as in the wild but well we also keep dogs on a leash to keep us company)

There's also an educational part about it. Because of these dolphin shows and movies with them they are perceived as cute, smart and happy so hunting them is frowned upon. If people had never seen a dolphin in real life or in a movie they would just be big fish to people and they would still be massively hunted.

What saddens me even more are the killer whales kept in captivity. There have been cases where they just killed themselves out of boredom/depression/... They also routinely hurt each other and there's not a single tank in the world that can keep them in an animal friendly way.
