As a designer, what safety considerations did you have to think about with the Neuralink device? The primary safety considerations weren’t so much on the device but on the robot. We had a small role to play, which was to psychologically transform their first-generation robot, which was exposed steel—you could argue it looked pretty ominous—to … Read more
The original version of this story appeared in Quanta Magazine. In recent decades, neuroscience has seen some stunning advances, and yet a critical part of the brain remains a mystery. I am referring to the cerebellum, so named for the Latin for “little brain,” which is situated like a bun at the back of the … Read more
There’s a lot to like about brain-computer interfaces, those sci-fi-sounding devices that jack into your skull and turn neural signals into software commands. Experimental BCIs help paralyzed people communicate, use the internet, and move prosthetic limbs. In recent years, the devices have even gone wireless. If mind-reading computers become part of everyday life, we’ll need … Read more
The company’s study included 74 participants with mild to moderate Alzheimer’s who received either the Cognito stimulation or a sham device that acted as a placebo. Subjects were asked to use the headset for an hour every day for six months. Compared with the placebo group, those who got the Cognito stimulation showed a 77 … Read more
The original version of this story appeared in Quanta Magazine. Whenever you’re actively performing a task—say, lifting weights at the gym or taking a hard exam—the parts of your brain required to carry it out become “active” when neurons step up their electrical activity. But is your brain active even when you’re zoning out on … Read more
Some Neuralink rivals, such as Precision Neuroscience, are developing implants that sit on top of the brain, or in the case of Synchron, a stentlike device that’s inserted into a blood vessel and sits against the brain. These devices aim to allow paralyzed people to communicate using digital devices by reading electrical patterns generated from … Read more
Earlier this year, Parkinson’s disease (PD) research entered a new era when the Michael J. Fox Foundation announced a momentous scientific breakthrough—the discovery of a biomarker for PD. It meant that, for the first time ever, we can now pinpoint the earliest known signs of the disease in Parkinson’s patients. This long-awaited new procedure is … Read more
It has been known for decades that the vast majority of human biological differences aren’t between groups, they’re from person to person. It’s weird that scientists and doctors still resort to sifting people into huge populations when trying to understand us: ethnicity, race, sex, and gender. 2024 will mark the year that they finally relinquish … Read more
In September, Elon Musk’s brain-implant company Neuralink announced the much-anticipated news that it would start recruiting volunteers for a clinical trial to test its device. Known as a brain-computer interface, or BCI, it collects electrical activity from neurons and interprets those signals into commands to control an external device. While Musk has said he ultimately … Read more
Clinical depression is considered one of the most treatable mood disorders, but neither the condition nor the drugs used against it are fully understood. First-line SSRI treatments (selective serotonin reuptake inhibitors) likely free up more of the neurotransmitter serotonin to improve communication between neurons. But the question of how SSRIs enduringly change a person’s mood … Read more
