I've been saying this for a while (just to my friends) - I think algorithms make these mistakes because there are no consequences for wrong answers. It is in the best interest of humans and living creatures to guess correctly, because we don't want to die. For example, tigers have "meaning" to us because they could kill us, food has "meaning" to us because we die without it, etc. etc. Nothing has "meaning" to predictive algorithms, which I think is a interesting and fundamental challenge to predictive modeling and machine learning in general.
Hmm....pretty complicated to detect things like depression with an EEG cap. Stress, may be easier...Still, I'm skeptical that this "huge boost in profits" doesn't just come from scaring people into thinking that their thoughts are being read.
I now have a bit more of an understanding of why anesthesiology is such an art - not enough of this stuff and you may paralyze someone without knocking them unconscious for a surgery. Too much, and you dangerously dampen the parts of the brainstem that control breathing and cardiac rhythms.
I'm curious though as to why consciousness goes before breathing does...if these drugs are given intravenously, wouldn't they diffuse to all parts of the brain equally, and cause just as much consciousness loss as breathing loss?

The official press release details the actual brain area in which this metabolism change was studied. The anterior cingulate cortex is involved in pretty much everything (attention, task-switching, self-monitoring, etc), so not super surprising but pretty cool nonetheless. Also not really "controversial", as any substantial behavioral change will necessarily produce corresponding changes in brain activity...Good to see that it can be reversed though.
From this article:
“No neuroscience experience is required: talent and drive matter far more,” the company says on the site. “We expect most of our team to come from other areas and industries.”
Eh...sounds like the bottleneck here will not be engineering machines, but getting them to produce meaningful changes in the brain at a neurological and psychological level. It doesn't matter how sophisticated your implants are if you don't have a way of reliably changing brain activity in a way that benefits a disease, which involves an incredibly sophisticated understanding of pathology at a molecular, cellular, and systems level, etc. etc. It's not really "plug and play"
Are you a veteran? If you are, I'm sure you're aware that there are unbelievable hurdles to re-integrating with civilian society, many of which can be helped with elevated community support and a steady job. True, there are many people in this country that work very hard, and you need to constantly retrain yourself and be creative to code, but vets that are reintegrating are playing by many different rules (because of serving our country!) that civilians are not: I can't see how any initiative providing specific help to this group to find jobs and meaning in the 21st century would be a waste.
Certainly Mr. (Mrs.) tech billionaire, I share your enthusiasm for integrating the human mind with a machine and believe it is indeed within our reach now that innovators such as yourself are stepping up to the challenge. A one-time donation of $15,000,000 to my lab to pursue our groundbreaking research that we were already doing anyway will ensure that humanity will praise your name forever, parades will be held in your honor, and all other entrepreneurs will gaze at you longingly at tech events.
Until we know more about how these algorithms make predictions, it'll be tricky integrating them into medicine: "I think you have a melanocytic lesion because I graduated medical school and have trained in dermatology for six years" still carries more weight than "Our highly accurate algorithm said you scored in a particular way on the 21 dimensions that we can't quite correlate to anything tangible, but it suggests you need this invasive surgery".
I feel like I read stupid article titles like this every week (mostly on futurist tech type sites! "EXTREME TECH", yarrrr) about how team of neuroscientists has found the center for "free will" or have developed a new algorithm can "predict human thoughts" or some bullshit.
An fMRI study in Attention, Perception, & Psychophysics that shows that spontaneously switching attention between two screens with stuff on them activates the frontal lobe (planning), the basal ganglia (action selection), then the parietal lobe (just a total guess here, but maybe the part of the parietal lobe involved in spatial orientation?) is not appropriate to use for the claim that we've "found the free will center". Just because your attention switches to something, doesn't mean it's free will, either! When you gaze at different parts of a piece of art, are you using "free will" every time you move your eyes, or letting aspects of the picture attract your gaze?
Holy smokes. This is bad. Memory gets a lot of attention because it's sexy and everyone has them and they are obviously incredibly clinically relevant (PTSD, alzheimers, etc.), but I think when anybody can do a FRACTION of what this is alluding to...we will have heard about it before PBS releases this truly groundbreaking and exciting news in a special called "Memory Hackers"...The Telegraph isn't doing itself any favors with this bullshit either.
One thing I can't help but notice in the original post is that the controversy this stirred up was a couple of comments in a thread written by guys, one of which had a vague reference to a feminist.
So...although I'm sure this controversy might evoke bad memories about being shut down or censored by feminists (trigger warning, yall), there was actually just the one woman who had a opinion about it, who may or may have not have even called herself a feminist. Before you cry about it as being some wicked extension of the doom-bringing matriarchical victimhood SJW superpower...take a deep breath

To one day direct them down a spine and into some new prosthetic legs.

This is really interesting, thanks!

Ah, this is so excellent. Thanks for sharing. I'm a neuroscience/medicine student and this is what keeps me awake at night...We'll get there one day!
