Directly into the brain: A 3D multifunctional and flexible neural interface

Although measuring the electrical activity of neurons is useful in many disciplines, making durable neural interfacing brain chip implants with negligible adverse effects has proven challenging. Now, scientists have developed a flexible multifunctional neural interface that can not only register local brain activity in real time, but also deliver a steady flow of drugs through innovative microfluidic channels, reducing tissue reactions to the chip. Their design could find widespread application ...
