Northwestern University researchers have developed a breakthrough wireless neurotechnology that delivers information directly to the brain using patterns of light, completely bypassing the body’s natural sensory pathways. The soft, flexible implant sits under the scalp but above the skull, where micro-LEDs shine precise light signals through the bone to activate targeted neurons across the cortex.
The system opens the door to a new class of neuro-prosthetics that could one day restore sensory function, deliver artificial vision or hearing cues, enhance stroke rehabilitation, control pain without medication, or provide richer feedback for prosthetic limbs. The study, “Patterned wireless transcranial optogenetics generates artificial perception,” was published in Nature Neuroscience.
