Neuralace™ is a glimpse of what’s possible in the future of BCI.

This patent pending concept technology is the start of Blackrock’s journey toward whole-brain data capture–with transformative potential for the way neurological disorders are treated. With over 10,000 channels and a flexible lace structure that seamlessly conforms to the brain, Neuralace has potential applications in vision and memory restoration, performance prediction, and the treatment of mental health disorders like depression.

Neuralace is:
Ultra-High Channel Count | Wireless | Customizable | Flexible | Thinner than an eyelash.

The possibilities are endless… Whole-brain data capture | Seamless connectivity | Improved biocompatibility About Blackrock Neurotech Blackrock Neurotech is a team of the world’s leading engineers, neuroscientists, and visionaries. Our mission is simple: We want people with neurological disorders to walk, talk, see, hear, and feel again. We’re engineering the next generation of neural implants, including implantable brain-computer interface technology that restores function and independence to individuals with neurological disorders.

Blackrock’s long-tested NeuroPort® Array, widely considered the gold standard of high-channel neural interfacing, has been used in human BCIs since 2004 and powered many of the field’s most significant milestones. In clinical trials, patients using Blackrock’s BCI have regained tactile function, movement of their own limbs and prosthetics, and the ability to control digital devices, despite diagnoses of paralysis and other neurological disorders.

While Blackrock’s BCI enables patients to execute sophisticated functions without reliance on assistive technologies, next-generation BCIs for areas such as vision and memory restoration, performance prediction, and treatment of mental health disorders like depression will need to interface with more neurons.

Neuralace is designed to capitalize on this need; with 10,000+ channels and the entire scalable system integrated on an extremely flexible lace-structured chip, it could capture data that is orders of magnitude greater than existing electrodes, allowing for an exponential increase in capability and intuitiveness.

The more vividly a person imagines something, the more likely it is that they believe it’s real, finds a new study by University College London researchers.

The research, published in Nature Communications, involved more than 600 participants who took part in an online experiment, where they were asked to imagine images of alternating black and white lines while looking at a computer screen.

After they imagined a stimulus, participants then had to report how vividly they were able to visualize it.

The function of the human brain is exceptional, driving all aspects of our thoughts and creativity. Yet the part of the human brain—the neocortex—responsible for such cognitive functions has a similar overall structure to other mammals.

Through close collaboration between The University of Queensland (UQ), The Mater Hospital and the Royal Brisbane and Women’s Hospital, researchers have discovered the human ’s enhanced processing power may stem from differences in the structure and function of our neurons.

The results of this study have been published in Cell Reports as “High-fidelity dendritic sodium spike generation in human layer 2/3 neocortical pyramidal neurons.”

There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers at Chalmers University have now, for the first time in Sweden, used a quantum computer to undertake calculations within a real-life case in chemistry.

“Quantum computers could in theory be used to handle cases where electrons and atomic nuclei move in more complicated ways. If we can learn to utilize their full potential, we should be able to advance the boundaries of what is possible to calculate and understand,” says Martin Rahm, Associate Professor in Theoretical Chemistry at the Department of Chemistry and Chemical Engineering, who has led the study.

Within the field of quantum chemistry, the laws of quantum mechanics are used to understand which are possible, which structures and materials can be developed, and what characteristics they have. Such studies are normally undertaken with the help of super computers, built with conventional logical circuits. There is however a limit for which calculations conventional computers can handle. Because the laws of quantum mechanics describe the behavior of nature on a subatomic level, many researchers believe that a quantum computer should be better equipped to perform molecular calculations than a conventional computer.

Deep brain stimulation (DBS) is an experimental treatment strategy which uses an implanted device to help patients with severe depression who have reached a point where no other treatment works.

But despite her involvement in the DBS collaboration, which involves neuroscientists, neurosurgeons, electrophysiologists, engineers and computer scientists, neurologist Helen Mayberg does not see it as a long-term solution.

“I hope I live long enough to see that people won’t require a hole in their brain and a device implanted in this way,” she says. “I often have a nightmare with my tombstone that kind of reads like, what did she think she was doing?”

Providing increased resistance to outside interference, topological qubits create a more stable foundation than conventional qubits. This increased stability allows the quantum computer to perform computations that can uncover solutions to some of the world’s toughest problems.

While qubits can be developed in a variety of ways, the topological qubit will be the first of its kind, requiring innovative approaches from design through development. Materials containing the properties needed for this new technology cannot be found in nature—they must be created. Microsoft brought together experts from condensed matter physics, mathematics, and materials science to develop a unique approach producing specialized crystals with the properties needed to make the topological qubit a reality.

Among the biggest environmental problems of our time, micro-and nanoplastic particles (MNPs) can enter the body in various ways, including through food. And now for the first time, research conducted at MedUni Vienna has shown how these minute particles manage to breach the blood-brain barrier and as a consequence penetrate the brain. The newly discovered mechanism provides the basis for further research to protect humans and the environment.

Published in the journal Nanomaterials, the study was carried out in an with oral administration of MNPs, in this case polystyrene, a widely-used plastic which is also found in . Led by Lukas Kenner (Department of Pathology at MedUni Vienna and Department of Laboratory Animal Pathology at Vetmeduni) and Oldamur Hollóczki (Department of Physical Chemistry, University of Debrecen, Hungary) the research team was able to determine that tiny polystyrene particles could be detected in the brain just two hours after ingestion.

The mechanism that enabled them to breach the was previously unknown to medical science. “With the help of computer models, we discovered that a certain (biomolecular corona) was crucial in enabling plastic particles to pass into the brain,” Oldamur Hollóczki explained.
