Brain device that reads inner thoughts aloud
From counting the number of people in a room to reading this sentence in your head, we are constantly harnessing our ability for inner speech. But what happens when scientists make that internal monologue external? In a paper published today in Cell, researchers describe using brain implants and new data analysis techniques to isolate the…

New Brain Device Is First to Read Out Inner Speech
And on the cutting edge of this field, neuroscientists have more recently developed brain implants that can turn neural signals directly into whole words. These brain-computer interfaces (BCIs) largely require users to physically attempt to speak, however—and that can be a slow and tiring process. But now a new development in neural prosthetics changes…

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…

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…

Plug-and-play brain–computer interface
Brain–computer interfaces (BCIs) offer the potential for people with severe motor disabilities to control external assistive devices with their mind. Current BCI systems are limited, however, by the need for daily recalibration of the decoder that converts neural activity into control signals. Researchers at the UC San Francisco Weill Institute for Neurosciences have now employed machine…

Brain-machine interface set to improve life for amputees
A newly designed brain-machine interface dramatically improves performance and reduces mental and physical stress for people with a leg amputated above the knee.

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…
