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.
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.

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).
Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.
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.
A place for discussions about neuroscience and neuroscience careers.
I started a neuroscience community for anyone interested in neuroscience, feel free to join :)
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 a computational neuroscience student and researcher. On this channel we seek to understand the brain and do deep explorations of interesting topics & papers from neuroscience (and related fields)

Last year, Monash University scientists created the "DishBrain" – a semi-biological computer chip with some 800,000 human and mouse brain cells lab-grown into its electrodes. Demonstrating something like sentience, it learned to play Pong within five minutes.

Hi everyone!
I’ve set up this community for anyone who’s interested in neuroscience.
Anyone is welcome: students, researchers, enthousiasts, …
!neuro@lemmy.world https://lemmy.world/c/neuro
For anyone specifically interested in neuroscience: we’re trying to create a neuroscience community over at: !neuro@lemmy.world
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.

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

Unfortunately this was pretty painful and uncomfortable.
Eyes in general are crazy, the last common ancestor between octopuses and humans didn’t even have eyes so both types of eyes developed independently.
What kind of things are you working on right now? Are you a student? Phd? Working in industry? Let’s talk :)
Welcome everyone. Let’s make this a friendly place for neuroscience enthousiasts.
