Tiny Brain Implant Can Do Three Jobs at Once

Topic: Neuroscience

Scientists from DTU and other institutions created a tiny brain implant that can record neural activity, deliver medication, and apply electrical or light stimulation. This device is called the microfluidic Axialtrode (mAxialtrode) and could help researchers study the brain and develop treatments for conditions like epilepsy.

Scientists have developed a new type of brain implant that's very thin and can do three jobs at once.

This implant, called the microfluidic Axialtrode (mAxialtrode), was created by researchers from DTU, the University of Copenhagen, University College London, and other institutions. It has microscopic channels that can transport liquids and hold tiny metal wires to measure electrical activity in the brain.

The mAxialtrode is designed to provide multiple functional points along its length, allowing researchers to record neural activity and deliver medication to specific locations across different parts of the brain. This could help scientists study how signals travel through the brain during processes like epilepsy, memory, and decision-making.

One of the main advantages of the mAxialtrode is that several capabilities can be combined within a single implant. This means researchers can perform more precise experiments while reducing the need for multiple devices inserted into the brain.

The new implant differs from current ones because it's made of soft, plastic-like optical fibers and has a specially angled tip that makes it smaller and reduces damage when placed in the brain.

Why It Matters

This breakthrough could lead to better treatments for neurological conditions like epilepsy. It also shows how scientists are working to develop more precise tools to study the brain.
