Neural Probes for Brain-Computer Interfaces Mimic Real Neurons

Brain-computer interfaces, those that could restore function in severely disabled people and give them ability to control robotic arms and other devices, depend on neural probes implanted into the brain. These technologies tend to work pretty well at first, but over time they draw attention of the surrounding immune system and the brain’s defensive mechanisms, … Continue reading

Neural Probes That Mimic Real Neurons May Revolutionize Brain-Computer Interfaces

Neural probes are some of the best tools for studying how the brain functions, and they also have great potential for therapeutic applications. Brain-computer interfaces can allow paralyzed people to regain function and even locked-in patients may soon be able to communicate with the rest of the world. Though there’s a great deal of progress … Continue reading

Light-Activated Tether-Free Neural Stimulation Device

Researchers at the University of Pittsburgh have developed an ultra-small implantable neural stimulation device that can be activated using a laser and which doesn’t require a cable that tethers it to a controller outside the body. The researchers hope that the device could pave the way for less invasive neural stimulation therapy in neurological disorders … Continue reading

Tumor Monorail Lures Brain Tumor Cells Toward Death, Now FDA Breakthrough Device

Brain tumors are extremely difficult to treat due to their hard-to-access location and because the blood-brain barrier prevents most drugs from reaching their targets. A new device called “Tumor Monorail,” which cajoles tumors to crawl into a container, just received the FDA’s “breakthrough” designation. The new designation will speed the device through the rest of the … Continue reading

Nerve-on-a-Chip to Improve Functionality of Neuroprosthetic Devices

Scientists at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have created a special device to be able to stimulate and record signals from and to peripheral nerve fibers on a specialty chip. The device can be used to repeatedly stimulate and record the returning electric activity with high resolution, potentially helping to develop future … Continue reading

Biodegradable Implant Stimulates Injured Nerves to Speed Up Healing

Scientists at Washington University School of Medicine and Northwestern University created an implant to deliver electric impulses to damaged nerves, helping to heal them, and that eventually biodegrades and leaves the body. It’s about the size of a U.S. quarter coin and operates for about two weeks before losing power and breaking up into microscopic … Continue reading

Seizure Control Device Delivers Drugs Inside Brain

A collaboration between researchers at University of Cambridge in the UK and École Nationale Supérieure des Mines and INSERM in France has developed a device that can sense electrical brain activity and deliver a pre-loaded drug dose in response. It has already been tried on mice undergoing seizures, releasing a native brain chemical that is … Continue reading

3D Printed Silicone and Stem Cell Implant to Treat Spinal Cord Injuries

Spinal cord injuries are notorious for the disabilities they cause and for the difficulty of finding a way to fix them. At the University of Minnesota researchers are pointing to a potential solution in the form of 3D printed scaffolds seeded with neuronal stem cells. The team has already created a prototype device, made of … Continue reading

Soft and Highly Flexible Neural Interfaces Prevent Injury to Brain

While rigid neural interfaces can read brain activity and stimulate it quite well, these devices end up damaging the soft brain tissue they come in contact with. Moreover, the body ends up attacking these implants and forming protective layers around them that quickly degrade the electrodes. “Imagine you have a bowl of Jell-O, and you … Continue reading

Soft Electronics for Long Term Neural Monitoring and Recording

Scientists at ETH Zurich in Switzerland, Linköping University in Sweden, and Columbia and NYU in New York City, have developed a highly flexible soft electronic neural interface probe that can be stretched to twice its original length. The device is suitable for long-term neural recording, and could help clinicians to diagnose and monitor neurological conditions … Continue reading
