IDK if this is the right place to post this, but it seems like the prediction for brain chips this year has been removed. May I ask why?

Next-gen "dry" electrodes used to control a robot via brain waves
By Ben Coxworth
https://newatlas.com/science/dry-electr ... rol-robot/
April 03, 2023

Although it is possible to control devices using brain waves, doing so usually involves having electrodes and conductive gel applied to one's head. Now, however, scientists have developed a new-and-improved type of "dry" electrode – and it's been used to mind-control a robot.

One of the obvious problems with conductive gel is the fact that users are left with a bunch of goop on their head, which they have to wash off. Additionally, some people's skin may have an allergic reaction to the gel.

Dry electrodes which don't require gel do exist, but they tend to be flat and rigid. This means that they don't conform well to the rounded contours of the head, and they have difficulty making contact with the skin if hairs are in the way. As a result, they tend to not perform as well as "wet" electrodes.

New Hope for Those Living With Paralysis: Nerve Stimulation Therapy Could Allow Patients To Regain Arm Function
https://scitechdaily.com/new-hope-for-t ... -function/

By Columbia University Irving Medical Center April 8, 2023
Spinal Cord Nerve Pain Illustration
A spinal cord injury is a serious medical condition that occurs when there is damage to the spinal cord, the central structure of the nervous system that runs from the brain down the back. This damage can result in a loss of movement, sensation, and other bodily functions below the site of the injury.

A promising nerve stimulation therapy has been developed at Columbia University’s Vagelos College of Physicians and Surgeons, which has shown positive results in animal studies. This therapy has the potential to restore arm function in individuals with spinal cord injuries, offering a new hope for those affected by this debilitating condition.

“The stimulation technique targets the nervous system connections spared by injury,” says Jason Carmel, MD, Ph.D., a neurologist at Columbia University and NewYork-Presbyterian who is leading the research, “enabling them to take over some of the lost function.”

The findings were recently published in the journal Brain.
A personal quest to develop treatments for people with paralysis

In 1999, when Carmel was a second-year medical student at Columbia, his identical twin brother suffered a spinal cord injury, paralyzing him from the chest down and limiting the use of his hands.

Carmel’s life changed that day, too. His brother’s injury ultimately led Carmel to become a neurologist and a neuroscientist, with the goal of developing new treatments to restore movement in people living with paralysis.

In recent years, some high-profile studies of spinal cord electrical stimulation have allowed a few people with incomplete paralysis to begin to stand and take steps again.

Carmel’s approach is different because it targets the arm and hand and because it pairs brain and spinal cord stimulation, with electrical stimulation of the brain followed by stimulation of the spinal cord. “When the two signals converge at the level of the spinal cord, within about 10 milliseconds of each other, we get the strongest effect,” he says, “and the combination appears to enable the remaining connections in the spinal cord to take control.”

See, now this is the news that excites me and I don't see how it doesn't get people talking. Noninvasive dry BCI allows user to control robot. Imagine what all could be done if such BCI's were cheap and plentiful, all the tasks people would literally set their minds to!

Ok see now THIS is cool lol! Guess it must be pretty old to be in public relatively quickly. The mind control as aspect is pretty freaky.

Mind reading? New AI system can translate a person’s brain activity into a continuous stream of text

https://www.psypost.org/2023/05/mind-re ... text-80255
by Christina Maher
May 2, 2023
The technology to decode our thoughts is drawing ever closer. Neuroscientists at the University of Texas have for the first time decoded data from non-invasive brain scans and used them to reconstruct language and meaning from stories that people hear, see or even imagine.

In a new study published in Nature Neuroscience, Alexander Huth and colleagues successfully recovered the gist of language and sometimes exact phrases from functional magnetic resonance imaging (fMRI) brain recordings of three participants.

Technology that can create language from brain signals could be enormously useful for people who cannot speak due to conditions such as motor neurone disease. At the same time, it raises concerns for the future privacy of our thoughts.

Deployable electrodes for minimally invasive craniosurgery
https://medicalxpress.com/news/2023-05- ... rgery.html
by Ecole Polytechnique Federale de Lausanne
Stephanie Lacour's specialty is the development of flexible electrodes that adapt to a moving body, providing more reliable connections with the nervous system. Her work is inherently interdisciplinary.

So when a neurosurgeon asked Lacour and her team to come up with minimally invasive electrodes for insertion through a human skull, they came up with an elegant solution that takes full advantage of their expertise in compliant electrodes, and is inspired by soft robotics actuation. The results are published in Science Robotics.

The challenge? To insert a large cortical electrode array through a small hole in the skull, deploying the device in a space that measures about 1 mm between the skull and the surface of the brain—without damaging the brain.

Soft 'e-skin' generates nerve-like impulses that talk to the brain
https://medicalxpress.com/news/2023-05- ... ulses.html
by Andrew Myers, Stanford University

Mechanoreceptors in human skin can sense the delicate weight of a butterfly, feel the heat of a nearby flame or a cool drink, understand whether a hand is raised in a fist or a peace sign, and count the pulse of a loved one with a gentle touch. Engineers eager to create artificial electronic skin have so far been able to fashion soft, flexible materials that mimic each of these remarkable senses, but never have they created a single sheet with skin-like materials that can directly talk to the brain—until now.

While previous efforts required rigid electronics to convert the sensed signal into electrical pulses that the brain can read, researchers at Stanford University have produced soft integrated circuits that convert sensed pressure or temperature to electrical signals similar to the nerve impulses to communicate with the brain. The researchers hope someday that those signals might be directed to implanted wireless communication chips in the peripheral nerve to allow amputees to control prosthetic limbs. Other potential uses might include new-age implantable or wearable medical devices.
