Silicon Chips as Artificial Neurons

Researchers at the University of Bath in the UK have developed low-power silicon chips that mimic the electrical activity of neurons. This breakthrough could enable the small chips to function as artificial neurons in numerous implants and medical devices, and the technology has significant potential in treating a wide range of chronic diseases, in (Read more...)

SOMATOM On.site: A Portable CT Scanner for Bedside Head Exams

At the ongoing RSNA conference in Chicago, a gathering of the world’s radiologists, Siemens Healthineers introduced its SOMATOM On.site CT scanner that can be wheeled right into patient rooms for bedside exams. Currently, patients requiring a head CT have to be taken to wherever the scanner is, but the mobility of the SOMATOM On.site allows [ (Read more...)

Injectable Electrodes for Neuromodulation

Researchers at the University of Wisconsin-Madison have developed an injectable flexible electrode that can aid in neuromodulation therapy, potentially replacing more rigid electrodes that do not mesh well with soft tissues. The injectable material consists of a silicone gel and small metal particles, and it forms a flexible bolus when injected aro (Read more...)

Nanoparticles Cross Blood-Brain Barrier to Treat Stroke

Ischemic strokes can cause havoc in the brain, but early and properly directed treatment can mitigate a lot of damage. While there are a number of options to unclog blocked arteries, the potential to provide additional drug therapy remains mostly unexplored because of the difficulty in getting medications past the blood-brain barrier. Now, research (Read more...)

Peptide Particles Ferry Drugs Across Blood-Brain Barrier

Most drugs, genetic materials, and other therapeutic agents are very difficult to use inside the brain because of the blood-brain barrier. There have been attempts to use ultrasound and microbubbles to create temporary passages through the barrier, including as a possible therapy for Alzheimer’s disease, but this is approach is not easy or id (Read more...)

3D Microenvironments to Grow Brain Tumors in Lab

Clinical researchers are constantly thwarted by the inability to quickly and easily try new therapies in tumors and other disease targets. Tumors within the brain are particularly hard to study because of the difficulty with access and the incredible fragility of nearby tissues. Researchers at Tufts University have just developed a way to create an (Read more...)

Exoskeleton Walks to Brain’s Commands

Powered exoskeletons are used to help people with lower limb paralysis get on their feet and allow post-stroke patients to recover faster. They’re pretty impressive devices, but people who are severely disabled, including those suffering from tetraplegia, can’t get much benefit from them. Now, a team of researchers in France has succeed (Read more...)
