Intracortical recording interfaces: current challenges to chronic recording function.

ACS Chemical Neuroscience, 2015
Brain Computer Interfaces (BCIs) offer significant hope to tetraplegic and paraplegic individuals. This technology relies on extracting and translating motor intent to facilitate control of a computer cursor or to enable fine control of an external assistive device such as a prosthetic limb.

A new chronic recording intracortical microelectrode

Medical & Biological Engineering, 2006
Chronic recording intracortical microelectrodes (c.r.i.m.s) maintain connections between external devices and single neural elements in the cerebral cortices of unrestrained animals. Such electrodes are tethered to the skull by means of an ultraflexible lead and cemented to the surface of the brain by a drop of biodegradable adhesive, and they are ...

Long-term chronic recording from cortical neurons.

Experimental Neurology, 1976
Abstract Chronic microelectrodes were implanted in the hand-arm area of the precentral motor cortex of monkeys to obtain long-term recordings from individual neurons. Eleven of the 12 implanted electrodes provided single unit activity during some period of the 223 days of recording in one animal.

Chronically implanted intrafascicular recording electrodes

Annals of Biomedical Engineering, 1991
A newly designed intrafascicular electrode for chronic neural recording was studied by implanting 12 electrodes in the radial nerves of 6 cats for 6 months. Action potentials were monitored at specified intervals throughout the experiment. The number and size of the signals recorded suggest that this type of electrode provides information that is ...

Smartphone for monitoring basic vital signs: miniaturized, near-field communication based devices for chronic recording of health

, 2020
Imperceptible chronic recording of health status is vital to realize precision digital medicine to improve current diagnostic and treatment capabilities. Current sensing hardware is lacking such capabilities presenting a bottleneck for progress.

Noninvasive Chronic Recording of Auditory Nerve Potentials

Annals of Otology, Rhinology & Laryngology, 1978
A system is described which allows repeated, noninvasive recording of auditory nerve responses in the cat to transient acoustic stimuli using a closed acoustic system. N1 responses to clicks are recorded from a stainless steel ring electrode at the end of a hollow earbar, the tapered end of which is made of insulating plastic.

Chronic recording and electrochemical performance of amorphous silicon carbide-coated Utah electrode arrays implanted in rat motor cortex

Journal of Neural Engineering, 2019
Objective. Clinical applications of implantable microelectrode arrays are currently limited by device failure due to, in part, mechanical and electrochemical failure modes.
