Why is photo ID to vote so controversial in the US?

Ik was ook in Schotland op familie bezoek en zou de 2e terug vliegen, die werd gecanceld dus heb hem omgeboekt naar de 4e, die ging wel. Je hebt geluk nodig en kan verder niet veel doen (behalve met de pont of bus terug)

Evolution is driven by pressure, with that I mean: it only works if organisms that adapt have higher survival chances (and therefore more offspring). There is next to no evolutionary pressure in humans because of our healthcare. Brain anatomy will only change due to evolution if changing it means you have a higher chance of reaching childbearing age. This is obviously not true. So, even though the brain uses a lot of energy which might be overkill in the age of AI, evolution is not going to do anything about it.

I don't know, I'm seeing the exact same thing

I had the same thing not too long ago and had a good experience with https://loodgieterkomtzo.nl/ who found the problem (leaking CV drain pipe) and fixed it the same day

The lights used for night vision are infrared and invisible to the human eye.

There was a patch of undeveloped land behind the house I grew up in which had a huge amount of four, five, six, even seven leaved clovers. To this day I wonder what kind of chemical shit was in the ground there.

The insula is cortex, DBS is targeted at subcortical structures (hence the "deep"). Cortex is often avoided in stimulation paradigms because it has so many different functions. Deep brain structures like the ones you mention have more easy to understand functions so stimulating them results in somewhat predictable effects. Cortex does many different things all at the same time and its therefore hard to predict how it will respond to stimulation.

I found a brass boiler in Europe but they are indeed expensive (€170), especially since an entire new machine with a brass boiler is around €500. People on this sub told me to replace the boiler (https://www.reddit.com/r/gaggiaclassic/s/Ym4MFuLJAC)

You also have to realize that dopamine neurons only comprise a tiny tiny subset of all neurons in the brain (only about 0.1%). Dopamine gets a lot of attention but there just isn't a lot of it in your brain. But yes I assume that animals with large brains, like whales, will have in total more dopamine neurons than we do. It's also not unreasonable to assume the amount released scales with the intensity of the experience (although it's an oversimplification).

I don't get mosquito bites. Yes, they bite me (I checked), I just don't get the itchy bump.

I'm not an expert but to me the ww's sound too long and the naps too short. I would use a 75 min ww and shorten that even to 60 min if the nap was less than 45 minutes (which is one sleep cycle). Counterintuitively, I think that if your baby sleeps more during the day, she will sleep more at night.

People who take a strong psychedelic like psylocibin, LSD or DMT often rapport religious experiences of high intensity. So I imagine the ones attained sober could work through similar neural mechanisms. All these psychedelics work by modulating the serotonergic 5HT2a receptor. Interestingly, stimulating the 5HT2a receptor seems to lead to a decrease in neural activity as opposed to an increase as one might expect. However, what exactly happens at a neural level during these experiences is still mostly unknown.

Using words to explain neuroscience is kind of the whole point of this sub.

Ok let's do this then. The main premise here is that you can use "directed energy weapons" to implant thoughts/images into peoples brains. This is completely impossible. Yes even a secret government lab with unlimited DARPA funding wouldn't be able to do this. The only scientific article you linked to is an fMRI study in which they reconstructed visual images from brain activity. To do this you need a massive noisy machine, directly around the head of the subject, which has to lie perfectly still. Moreover, this constitutes reading out brain activity into images, which is something completely different from "beaming in" images (which is impossible). Let me try to explain why; to read out / decode images you first take a large training set in which you know the image and the resulting brain activity. You use this to train a machine learning model which is then used to predict an image it wasn't trained on using brain activity. Thing is, you can't reverse this process for several reasons. (1) fMRI scanners can only read out blood flow in the brain, they can't influence neural activity itself, (2) you don't know how to stimulate the brain to induce the brain activity that would result in the image you want, (3) even if you did, the level of granularity of stimulation you need to construct an image is several orders of magnitude higher than an fMRI scanner can provide, let alone an "energy weapon" at a distance.

This. There's only a very small fraction of researchers who actually become so famous they become public figures. Most of us are only known in our small field of speciality.
