I wonder if you could use this stuff for brain scans.
Neuralink, the US neurotechnology firm co-founded by billionaire entrepreneur Elon Musk, has begun recruiting key employees to run its clinical trials, signaling that it’s inching closer to starting human testing of its brain implants.
The company has posted advertisements to hire a clinical trial director and a clinical trial coordinator. The ads note that the staffers will “work closely with some of the most innovative doctors and top engineers, as well as working with Neuralink’s first clinical trial participants.” Neuralink said the director will lead and help build its clinical research team and will develop “regulatory interactions that come with a fast-paced and ever-evolving environment.”

For example, functional near-infrared spectroscopy (fNIRS) is a widely used noninvasive imaging technique that employs near-infrared light (wavelength 700 nm) to determine the relative concentration of hemoglobin in the brain, via differences in the light absorption patterns of hemoglobin.
Recent advances in brain imaging techniques facilitate accurate, high-resolution observations of the brain and its functions. For example, functional near-infrared spectroscopy (fNIRS) is a widely used noninvasive imaging technique that employs near-infrared light (wavelength 700 nm) to determine the relative concentration of hemoglobin in the brain, via differences in the light absorption patterns of hemoglobin.
Most noninvasive brain scanning systems use continuous-wave fNIRS, where the tissue is irradiated by a constant stream of photons. However, these systems cannot differentiate between scattered and absorbed photons. A recent advancement to this technique is time-domain (TD)-fNIRS, which uses picosecond pulses of light and fast detectors to estimate photon scattering and absorption in tissues. However, such systems are expensive and complex and have a large form factor, limiting their widespread adoption.
To overcome these challenges, researchers from Kernel, a neurotechnology company, have developed a wearable headset based on TD-fNIRS technology. This device, called “Kernel Flow,” weighs 2.05 kg and contains 52 modules arranged in four plates that fit on either side of the head. The specifications and performance of the Kernel Flow system are reported in the Journal of Biomedical Optics (JBO).
Summary: The body relies on multiple maps based on the choice of the motor system.

Our brain maps out our body to facilitate accurate motor control; disorders of this body map result in motor deficits. For a century, the body map has been thought to have applied to all types of motor actions. Yet scientists have begun to query how the body map operates when executing different motor actions, such as moving your eyes and hands together.
High-resolution recordings of electrical signals from the surface of the brain could improve surgeons’ ability to remove brain tumors and treat epilepsy, and could open up new possibilities for medium-and longer-term brain-computer interfaces.
A team of engineers, surgeons, and medical researchers has published data from both humans and rats demonstrating that a new array of brain sensors can record electrical signals directly from the surface of the human brain in record-breaking detail. The new brain sensors feature densely packed grids of either 1,024 or 2,048 embedded electrocorticography (ECoG) sensors. The paper was published by the journal Science Translational Medicine on January 19, 2022.

Church points to factors that helped make such a success of three of the top COVID-19 vaccine technologies. For one thing, they all used gene therapy technologies, and each was a new method relative to the past and to each other. For instance, the AstraZeneca vaccine was based on an adenovirus capsid containing double-stranded DNA as opposed to an adeno-associated virus (AAV) of the Johnson & Johnson/Janssen vaccine, while the Moderna and Pfizer/BioNTech vaccines were based on single-stranded mRNA inside lipid nanoparticles.
“Implementation science is the unsung handmaiden of biomedical discovery!”
Secondly, each of them was approved by the FDA 10 times faster than the vast majority of therapeutic products, and finally, the cost per vaccine has been as low as $2 per dose for the United Nations’ COVAX global access program. That’s about a million times cheaper than Zolgensma, he says, referring to the AAV gene therapy medication used to treat spinal muscular atrophy. So since “any one of these could spark a revolution,” according to Church, imagine what could happen in the next 12 months if all four factors pertain again?
In today’s video I show you how the Neurosity Crown works by making a prototype to control lights which is initiated by thinking about movement of my left arm.
This Brain Computer Interface video will cover these areas:
👉 Neurosity console overview.
👉 Neurosity console left arm thoughts training with Kinesis.
👉 Extending Unity Notion SDK to subscribe to Kinesis updates and therefore get the data into Unity for further usage.
👉 Simple LightController in Unity to turn on and off lights controlled by a Philips Hue Hub.

Computers play an important role in many aspects of life today. Digital computers are the most widely used, while quantum computers are well known. However, the least known computers are the so-called Stochastic Pulse Computers. Their work is based on highly parallel logical operations between trains of electrical pulses, where the pulses occur at random times, as in neurons, the nerve cells in the brains of humans and mammals.
Elon Musk’s Neuralink, the company that purports to implant computer chips in human brains, just took a critical step toward actually following through.
The brain implant firm is officially hiring a clinical trial director, which means Musk’s futuristic firm is finally ready, at least on its own terms, to give next-gen brain-computer interfaces (BCIs) a try.
