Scientists Make ‘Cyborg Worms’ with a Brain Guided by AI

Scientists have given artificial intelligence a direct line into the nervous systems of millimeter-long worms, letting it guide the creatures to a tasty target—and demonstrating intriguing brain-AI collaboration. They trained the AI with a methodology called deep-reinforcement learning; the same is used to help AI players learn to master games such as Go. An artificial neural network, software…

Brain-computer interface creates text on screen by decoding brain signals associated with handwriting

Brain-computer interface creates text on screen by decoding brain signals associated with handwriting

Scientists with the BrainGate research collaborative have, for the first time, used an implanted sensor to record the brain signals associated with handwriting and used those signals to create text on a computer in real time. In a study published in the journal Nature, a clinical trial participant with cervical spinal cord injury used the system to “type” words on a computer at a rate of 90…

Bioresorbable silicon electronic sensors for the brain

Bioresorbable silicon electronic sensors for the brain

Many procedures in modern clinical medicine rely on the use of electronic implants in treating conditions that range from acute coronary events to traumatic injury However, standard permanent electronic hardware acts as a nidus for infection: bacteria form biofilms along percutaneous wires, or seed haematogenously, with the potential to migrate within the body and to provoke immune-mediated…
