Sony Semiconductor has created a nerve cell sensing array with over 200,000 electrodes spread over a few square millimetres. Aimed at drug research, it allows experiments on nerve cells outside of a human or animal. Made in CMOS, it has 236 880 electrodes in a ~480 x 500 array across 5.5 x 5.9mm. The pixel spacing – 11.22μm square pixels ...
At Stanford University, researchers have found a way to record the activity of a single neuron without burrowing into the brain – of a rat in this case. Developed by Anqi Zhang and colleagues, the key part is a micro-probe that can be threaded through blood vessels as small as 100μm in diameter. Initially it is housed in a micro-catheter ...
Wireless ‘neurograins’, 48 of them, have been used to record rodent neural activity, at Brown University in Rhode Island. The sensing particles independently record electrical pulses made by neurons and send the signals to a central hub outside the skull for coordination and processing. “One of the big challenges in the field of brain-computer interfaces is engineering ways of probing as ...
Movement in the hand and fingers of a paralysed man have been temporarily restored using a brain implant linked to electrodes on his forearm. The system has been developed by teams at not-for-profit research firm Battelle and the Wexner Medical Center of Ohio State University, and has been dubbed NeuroLife. Ian Burkhart is the subject. “He participates in clinical sessions during which ...
