Researchers at Massa chusetts Institute of Technology (MIT) have created complex multimodal polymer fibers that have the ability to deliver drugs and optical signals into the brain. These fibers can be produced with the thickness less than that of a hair’s width. Standard neural probes have the ability to record a single signaling type, and this limits the amount of information that can be obtained from the brain at a specific point in time. Anikeeva of MIT states that polymers that possess characteristics similar to that of neural tissues make up these new fibers.
These fibers can stay in the body for a much longer period without affecting the surrounding delicate tissues. The various chanel in the fiber include conductive electrodes for carrying electrical signals, optical wave guides for carrying light and hollow tubes for carrying drugs.
drugs could be injected through the hollow channels into the brain. The electrical signals that occur in the neurons are recorded in real time and they would help ascertain the exact effect of the drugs.
