Researchers report their new findings could bring natural movement of prosthetic limbs closer to reality.
Combining machine learning with neuroprosthetic technology allowed a patient with paralysis to learn to control a computer cursor by utilizing brain activity without extensive daily retraining.
Researchers created a form of artificial vision for a blind woman with the aid of a brain implant position in the visual cortex. The results pave the way for the creation of visual brain prosthetics to help the blind to regain sight.
Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.
Researchers have developed a new prosthetic arm that stimulates the nerves in the amputated limb, allowing the patient to feel the sense of touch.
Findings about how the speech center is organized and how fluid speech occurs could lead to the development of neuroprosthetics capable of translating thoughts into speech, researchers report.
A prosthetic arm that is attached to the bone and controlled by electrodes implanted in nerves and muscles can operate more precisely than conventional prosthetic limbs. Researchers improved the neuroprosthetic hand by integrating tactile sensory feedback, so the patient can "feel" items.
Researchers electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart - one in Durham, N.C., and one in Natal, Brazil.
