Thought-to-Text Brain-Computer Interface: Interview with Florian Solzbacher, Chairman of Blackrock Neurotech

Blackrock Neurotech, a medical technology company based in Salt Lake City, created a suite of brain-computer interface systems with the goal of empowering patients to have increased independence and quality of life. This latest technology aims to restore written communication in patients who have difficulties in this regard, such as those affected (Read more...)

Wireless Photoelectric Implant for Optogenetics Research

Scientists at Ecole Polytechnique Fédérale de Lausanne in Switzerland created a wireless photoelectric implant that allows them to activate or suppress certain neurons in the mouse spinal cord. The flexible implant is controlled through Bluetooth and contains miniaturized LEDs that emit red light, which helps to avoid absorption and r (Read more...)

Laser-Assisted Bioprinting of Neurons

A team at Concordia University in Montreal have developed a technique called Laser-Induced Side Transfer (LIST) that allows for bioprinting of neurons. Low energy laser pulses are directed at a capillary containing a cell-laden bioink, resulting in microbubbles that eject a microjet of the ink onto the substrate below. The technique appears to be f (Read more...)

Steerable Catheter to Navigate Tortuous Blood Vessels in Brain

A team at University of California San Diego invented a way to make steerable catheters that can more precisely navigate the tortuous architecture of the brain vasculature. The device was bioinspired by delicate structures found in nature, including flagella and insect legs, and uses principles from soft robotics to create a hydraulic steering syst (Read more...)

Tiny Neural Sensors for Brain Computer Interfaces

Researchers at Brown University have developed wireless micro-implants that can function as a network of neural sensors and stimulators in the brain. The research team has dubbed their creation “neurograins,” which are intended to be implanted in the brain in large numbers. When inside, they can transmit data to an external communicatio (Read more...)

Neuromodulation for Lennox-Gastaut Syndrome: Interview with Martha Morrell, M.D., CMO of NeuroPace

NeuroPace, a medtech company based in California, has developed the RNS system, an implantable neuromodulation device for focal drug-resistant epilepsy. The system continuously monitors brain activity and then responds appropriately to target the seizure source in the brain for personalized seizure prevention. The company reports that the stimulati (Read more...)

Wireless Light Implant for Optogenetics Without Skull Damage

Researchers at the University of Arizona have overcome a major limitation of optogenetics with their wireless and battery-free implant that can shine light through the skull. The small device, which is implanted under the skin, could provide a light source for optogenetics that doesn’t require damage to the skull or brain. While optogenetics (Read more...)

Oscillating Magnetic Field Shrinks Glioblastoma Tumor

At the Houston Methodist Neurological Institute, researchers have developed a device that generates a magnetic field and used it to successfully shrink a glioblastoma tumor in a patient volunteer. The device is worn on the head each day during treatment, and uses an oscillating magnetic field to disrupt biochemical processes in cancer cells. While (Read more...)

Highly Maneuverable Magnetically Controlled Miniature Robots

Researchers at Nanyang Technological University, Singapore have developed miniature robots that are highly maneuverable, and can rapidly move in six degrees of freedom. These tiny devices are magnetic and can be controlled using an electromagnetic coil system that precisely manipulates the direction and strength of magnetic fields. The researchers (Read more...)

Brain Stimulation Lets User Feel Robotic Arm

Researchers at the University of Pittsburgh have demonstrated that providing direct sensory feedback into the brain dramatically enhanced an impaired patient’s control of a robotic arm. The arm was operated through a brain-computer interface, but the system also included brain implants in an area of the brain responsible for sensory feedback. (Read more...)

Light-Responsive Hydrogel to Fill Cerebral Aneurysms

Researchers at Pohang University of Science & Technology (POSTECH) in Korea have developed a new technique to treat cerebral aneurysms. Described in journal Advanced Materials, the treatment involves using a catheter to deliver an alignate hydrogel that is crosslinked in place within the aneurysm using light. The hydrogel is not degradable and (Read more...)

Mantis Shrimp-Inspired Camera to Detect Tumors During Surgery

Researchers at the University of Illinois Urbana-Champaign have developed a hexachromatic camera that can assist with tumor imaging during surgical removal. The device is inspired by the mantis shrimp which can perceive twelve colors, compared with just three colors that can be perceived by the human eye. The new camera can visualize tumors in the (Read more...)

Sugar Coated Brain Implants

Researchers at McGill University in Canada have developed a method to create and deliver brain implants that are a similar in consistency to the brain itself, which is a soft gelatinous tissue. The delicate silicone implants are created using sugar molds and delivered using a sugar needle, and their delicate consistency helps to ensure that [&helli (Read more...)
