Now Imagine having an electrode embedded in your brain in a surgical process that includes drilling holes in your skull to implant it. Now think about going by way of an MRI scan for medical analysis, when the steel electrode might react to the magnetic fields and vibrate, generate heat and even probably damage the brain. This can be a reality that patients who want deep brain stimulation might face.
Now, an examine revealed Nov. 18 in Nature Microsystems & Nanoengineering describes a promising improvement to the process developed by San Diego State University engineers, in collaboration with researchers at KIT, Germany. The SDSU analysis staff created a glassy carbon electrode as an alternative choice to the metallic model, and new findings present it doesn’t react to MRI scans, making it safer.
First, it was developed in 2017 in researcher Sam Kassegne’s MEMS lab at SDSU; the carbon model is designed to last more within the brain without getting corroded or deteriorated and to emit and obtain stronger signals. In 2018, the researchers showed that whereas the metal electrode degrades after 100 million cycles of electrical impulses utilized to it, the glassy carbon materials survived 3.5 billion cycles.
Deep brain stimulation—the place electrodes implanted within the brain produce electrical impulses that management irregular motion—is more and more getting used for these with motion issues that do not reply to remedy, similar to patients with Parkinson’s disease, tremors, and uncontrolled muscle contractions often known as dystonia.
With lab testing accomplished, Kassegne’s collaborators on the clinical aspect will now test the carbon electrode in patients, whereas Nimbalkar and Kassegne work on testing completely different types of carbon for use in future electrodes.
