Brain-computer interface

Scientists have successfully bridged the gap between organic and artificial. A team has created biohybrid synapses that let living cells communicate with electronic systems, not with electrical signals but with neurotransmitters like dopamine.

When it comes to accurately reading the brain's electrical signals, many systems utilize implantable electrodes. A new technology is reportedly less invasive yet just as accurate, as it swaps regular electrodes for ultra-thin wires.

Scientists studying brain-computer interfaces at Johns Hopkins University are reporting a big breakthrough, demonstrating a system that enables a quadriplegic to control and gain feedback from two prosthetics arms at once.

Scientists from the University of Grenoble have spent two years teaching a quadriplegic man to move his arms and legs, and even walk, using a brain-controlled AI exoskeleton.

Facebook has announced the purchase of CTRL-labs, a young company developing technology working on non-invasive systems that read your brain signals.

​Imagine if you were musically gifted yet paralyzed, so you had great difficulty writing down or performing the melodies that you thought up. Well, scientists have developed a system that could help. It allows users to write music using just the power of their mind.

A non-invasive robotic arm developed by University of Minnesota researchers could give the physically impaired a newfound sense of mobility without the risk of going under the knife.

By combining an EEG headset​ from Emotiv and an assistive communication app, Smartstones is bringing the power of speech to those with speech difficulties. The "think to speak" technology works by reading the brainwaves of the user and expressing them as phrases spoken through the app.

​Using a specialized sleeve, his own mind and a brain-implant smaller than a pea, a man paralyzed from the neck down has regained the ability to handle a variety of everyday objects.

Research at East Tennessee Sate University (ETSU) has suggested that brain-computer interfaces (BCIs) could help brainstem stroke patients suffering from locked-in syndrome to find their voice again, with very specific brainwaves serving as a typing finger for a virtual keyboard.
