Researchers at Sweden’s Lund University have been able to develop a flexible electrode that can be safely implanted in the brain and capture signals from single neurons. The electrode material is so flexible that it bends against the surface of water. The researchers were able to implant the electrode by encasing it in a rigid biocompatible gelatin that dissolves once the electrode is implanted.
This is another example of how techniques for studying the brain and brain function are advancing. Brain research has become a major focus in science and medicine, and will remain so over the next decade at least. Our expanding knowledge will generate new treatments for brain disease/dysfunction. Medical device design will be important in developing tools for brain study, as well as in developing treatment devices themselves.
