Oh hey, another BCI startup. This one seems promising. I published in the field so I'm happy to answer questions.

I did some digging over my morning coffee and couldn't find any more details about the AI features. If I had to guess they might have a machine learning algorithm which helps decode brain signals. The company website seemed more geared towards creating a platform for EEG research and didn't mention the AI at all? I may have missed it in my quick review.

I'm less familiar with visual evoked potentials, but they should be a lot easier to read than other neural signals. This is a big plus because it means the device tolerates more noise. I'm curious if it's reliable enough to function in the "real world" - some EEGs are so sensitive that they even pick up electrical noise from wires in the walls. You can post process some, but not all, of the noise from your environment.

I've felt the real BCI future is with functional near infrared devices but I'm yet to see a breakthrough into commercial devices.

Standard? Not really. But there's a tutorial here: https://github.com/miykael/3dprintyourbrain

Happy to answer some questions if you have issues

Interesting question. It depends. I linked Ev Fedorenko's Interesting Brain Project at MIT up above, they're doing a deep dive into questions like those.

Broadly speaking, if you're born with these anatomical anomalies, you'll be more or less normal. The article mentions the person in question had an IQ of 70, so that's lower than normal, but not intellectually impaired.

But acquired Brain damage almost always leads to impediments. Strokes and repeated concussions, physical injury, etc.

The brain is "plastic" when you're young, we like to say. That is, it's pliable and can mold into whatever shape it needs to in order to adapt to your environment. That plasticity disappears once you get older. It's how kids can learn language effortlessly - when you're born, you have the most neurons and synapses you'll ever have in your life. You'll keep the same neurons (unless you have a degenerative disorder or kill them with drugs), make new synapses as you learn, but broadly speaking as you grow up you prune synapses that aren't helpful.

This is also why kids can undergo massive resection surgeries (or in the olden days, severing of the corpus callosum) and grow up more or less normal.

In the US getting an MRI for "no reason" can be very expensive. Probably wouldn't have been covered by insurance.

Ev Fedorenko has done some of the best research in brain science, in my opinion. There's no better rabbit hole than her research!

Eh, college is hard and so was his sport. Sure, it's not an exhaustive battery of testing but I'm confident to say he's a normal dude.

That's the short of it - but we passed all brain data to a university affiliated neurologist for review. We also allowed participants to take a copy of their brain data if they wanted. I've got a CD of my own brain kicking around somewhere, and I even helped a few people 3D print their brains.

But, anything that I said about the participants brain opened me up to liability. What if I said their brain looked OK and there was a tumor? Or vice versa? The University felt I could be sued, so we were trained to not speak about their brain.

Well it's not quite water, it's cerebrospinal fluid and it plays a lot of important roles in waste clearance, immune protection, protection from concussion, and more.

Nope, not related to any disease I've ever seen. The best guess i have is fetal alcohol syndrome but it isn't a perfect match. It's just weird knowing he has a very odd shaped brain. And there's a lot of unknowns surrounding it.

What if he sees another doctor and they mention it to him? Would he be upset I didn't say anything? What if it is linked to some disease and I didn't tell him, and he gets sick?

What if it's hereditary and his kid has it, does it explain the motor delays? The premature birth? The problems they have with him sleeping?

Just a lot of unknowns.

We've actually seen a handful of them in the community. MIT has an "Interesting Brain Project" https://news.mit.edu/2023/studies-of-unusual-brains-reveal-insights-brain-organization-function-0221.

If you're born that way, odds are you'll be more or less normal. It's amazing to see how resilient the human brain is.

In fact, one woman in China was born without a cerebellum. She wasn't exactly normal per se, but she was alive and more or less healthy. Even though the cerebellum is smaller by volume it has about the same number of neurons as the cerebrum. So she just had half a brain. https://www.newscientist.com/article/mg22329861-900-woman-of-24-found-to-have-no-cerebellum-in-her-brain/

I ran a lot of MRIs for my PhD. I saw somewhere around 100-200 different brains. About 10% of them had abnormalities. Of all the technicians, scientists, and (non-clinical) doctors I spoke with, we all agreed this was a very high rate of discovery. All my friends graduated without seeing anything weird. My advisor liked to joke that I was cursed. Eventually I stopped inviting my friends to do my experiments because I didn't want to deal with the risk of them having an abnormality - thanks to some combination of HIPAA and medical liability laws, I wasn't allowed to say anything about it, even if asked point blank. I didn't like that very much.

I made one exception, as a friend of mine came in for a study and I saw a golf ball sized cyst in his sinus. He had it surgically removed and he told me he stopped snoring the next day. It felt good to make a difference for him.

But, I saw one brain similar to the one documented here. It belongs to one of my close friends. It was harrowing. Entire left hemisphere was malformed, the ventricles were way too big and the cortex was way too thin. But the right side of his brain was underdeveloped, maybe the size of a tennis ball.

The weirdest part, he is 100% normal. In fact, he competed at a high level of college athletics. Normal Cognition, normal motor function, great sense of humor, and a very caring person. Now he has a great job, wife and kid, and we hang out often. But I can't bring myself to say anything, and every time I see his son I wonder about his brain.
