15 for the ultra-processed disability ask thing!

Ok for reference that's

What’s something your disability has stopped you from learning or doing?

Fun story!

For my Ph.D. I studied brain computer interfaces. Specifically P300 brain computer interfaces. Here's my dissertation, for reference.

As far as I can tell, most people studying brain computer interfaces will ever use them. It might not be for their own communication needs (I'm a a part-time AAC user but I do just fine using my hands to access my AAC; I don't need a brain computer interface.) But if you work in a lab with brain computer interfaces, you're probably going to get called on to test that, like, new settings do what they say they do / that it's still possible to make selections / that the data collection method actually collects the data by using the interface. Plus we get tapped to be "neurotypical controls" (what my papers say) and/or "healthy controls" (what a lot of other people's papers say; I've also seen people alternate between the two) on a semi-regular basis, if we're close enough on whatever other demographics they're matching on to be reasonable.

I'm obviously not a neurotypical control. But I also cannot use a P300 brain computer interface, because that's basically dependent on flashing lights a bunch of times per second. So I got a Ph.D. studying a kind of brain computer interface that I cannot use.

(There are other kinds, some of which I can use. One particularly desperate masters student working with motor imagery brain computer interfaces tried to change his thesis wording to "controls without Parkinson's" so he could use me as a control. Pretty sure his supervisors made him take me back out though; his final thesis says both neurotypical control and healthy control.)

compared to this idea, the way ai art is or is made is nothing compared to my idea, the idea of bci (brain computer interface) technology that can read your mind, and put your ideas on screen, or a helmet who draws for you, if you can't draw very good

The Amazing World of Brain-Computer Interfaces

Brain-computer interfaces (BCIs) are innovative devices designed to create a communication pathway between an external output and a brain’s electrical activity. Sensors relay the electrophysiological signals transmitted between the neurons in grey matter to an external source, such as a computer or robotic limb, effectively turning an individual’s thoughts into physical actions. The brain chips that BCIs rely on may be surgically placed beneath the scalp, incorporated into a device that is worn or even implanted directly into brain tissue.

How Does This Technology Work?

Brain-computer interfaces work by capturing activity in the brain, which is done by placing electrodes close to where the ‘neural’ communication is occurring. The sensors measure the intensity and frequency of each spike of voltage, operating like a microphone.

The information gathered is fed through computer software and translated via a process called neural decoding. Machine learning algorithms (and other AI tools) convert the complex data sets gleaned from the brain’s activity into a programmable understanding of intention.

How Can BCIs Be Used?

Patient restoration issues caused by neurological problems or amputation may be alleviated with the use of BCI innovation; indeed, these devices are already being used as part of recovery techniques across a range of patient populations. In the future, as the technology continues to develop, these devices could help those with serious motor incapacities, both enhancing general quality of life and bringing down the cost of intensive care.

Those with a keen interest in this field, such as David Ollech, understand that the applications of BCIs include wireless headsets, robotic limbs and wheelchairs, smartphone and smart home device interfaces, and spellers. The latter could be helpful for those who are non-verbal following a severe injury or stroke, allowing users to access computer-augmented communication through eye movements.

Benefits of BCIs

As well as helping to restore motor and mobility functions for individuals who have suffered a serious injury or health condition, BCIs can also be used to treat neurological conditions and monitor mental health. Through neurofeedback techniques, BCIs may be able to help prevent conditions like fatigue and burnout, delivering electrical stimulation to specific areas of the brain. Looking ahead, these devices could alleviate a wide range of anxiety issues and even promote better sleep health.

Today, BCI systems are moving out of laboratory demonstrations and into an increasing number of exciting real-world applications.

Love how they're desperately trying to downplay Neuralink even as they admit it has advantages that, as far as is publicly known, no other version of this tech does. This tech has the potential to give countless people their lives back, but we've gotta dilute that message because it's more important that people not think anything positive about Elongated Muskrat.

why neuroscience is cool

space & the brain are like the two final frontiers

we know just enough to know we know nothing

there are radically new theories all. the. time. and even just in my research assistant work i've been able to meet with, talk to, and work with the people making them

it's such a philosophical science

potential to do a lot of good in fighting neurological diseases

things like BCI (brain computer interface) and OI (organoid intelligence) are soooooo new and anyone's game - motivation to study hard and be successful so i can take back my field from elon musk

machine learning is going to rapidly increase neuroscience progress i promise you. we get so caught up in AI stealing jobs but yes please steal my job of manually analyzing fMRI scans please i would much prefer to work on the science PLUS computational simulations will soon >>> animal testing to make all drug testing safer and more ethical !! we love ethical AI <3

collab with...everyone under the sun - psychologists, philosophers, ethicists, physicists, molecular biologists, chemists, drug development, machine learning, traditional computing, business, history, education, literally try to name a field we don't work with

it's the brain eeeeee

Perhaps controversial, but: why the hell do people wanna download fics as EPUBs? I'd vastly rather they be PDFs

Its the year 2050. I think about making a grilled cheese but my neuralink causes 14 ads to start playing over the recipe.

between joanns going under and firefox's stupid data decisions, it truly feels like my hobbies, my sources of joy, are going under and getting compromised. I have 2 things going for me: my little crafts and my computer stuffs. To have a major part of both of them get hit so badly, I am completely devastated. I didn't even get to fully accept the joanns closure before getting hit in the face with this firefox bullshit. I've been using firefox for over 15 years, since middle school when the whole game was firefox vs. opera vs. chrome. I've been a huge proponent of firefox, in part for browser diversity but also just the superior browsing experience (for my needs). Since middle school. And I had a feeling they might pull the rug, I was sortof eyeing some of the firefox forks as a backup plan, but man. The timing. And joanns going before I could even break out my sewing machine. Devastating. I had so much hope for life letting me enjoy things a year ago. I almost had my place organized so that I could do the things I enjoy. But grandmother died, sister moved back in, my dad moved across the country in his little car leaving me with half his stuff, big fires, disaster at work giving me so so much to clean up on top of my regular duties. At some point in January I gave up in cleaning out/organizing my apartment. Every few days, the mess irks me enough that it gets under my skin and I have a meltdown. But otherwise I try to ignore it. I'm so tired. I need at least a week off to fix it (and spring break next month is not gonna count bc I'm gonna have non-work things I need to take care of then). I actually just remembered now in this moment typing this that I was looking to find a new therapist in late january (before my work disaster). Oops. Not happening I guess. I can't even clean up my house to make space for my sewing machine, so the futile work for finding a therapist is most certainly out of the picture. Welcome new depressive funk, grief is an old friend, familiar. Or maybe grief is more like the mess on the kitchen counter, because it always seems to come back before I have a chance to properly wipe it away.

dads been getting back into making music in a big way and its so funny to have lots of back and forth about cool experimental stuff we've come across and i ask how his own tinkering is going and he tells me he's spent the last 2 days perfecting the setup on his RGB keyboard instead

Keep Brain Interfaces Open

[sevicia]

I wanted to make a cleaner summary of last week's classes and also review the classes I have this week since the material is already uploaded beforehand but I was feeling so horrible throughout the day that when I sat down I was just gonna look at the ones for tomorrow but I think I'm just gonna go to bed because I just gave my little numbers game a few tries and not even the joy of tribial elementary school-level math games is bringing my brain cells and/or full sentience back
