September 4, 2024 by Michaela Martinez, Duke University A new tool to model peripheral nerve stimulation rapidly discovered optimal electrical waveforms (white traces) which, when delivered through the metal contacts of a cuff electrode placed on the vagus nerve, activates only therapeutic target fibers (in green) to avoid side effects. The optimization process involves testing...
Pauline Anderson Transcranial alternating current stimulation (tACS), a noninvasive technique that uses low-intensity electrical currents to modulate brain activity, is an effective intervention for treating chronic insomnia, especially in older people, results of a relatively large study suggested. METHODOLOGY:The double-blind study included 124 adults with chronic insomnia (difficulty falling asleep or maintaining sleep and early...
By Matthew Herper Marc, a 62-year-old who has had Parkinson’s for 30 years, received an experimental treatment that appeared to notably improve his ability to keep his balance and walk without freezing up. An experimental treatment that delivers an electrical current to the spinal cord appeared to notably improve the ability of a man with Parkinson’s...
by Aaron Nieto, Baylor College of Medicine Study setup: electrical stimulation device, plugs and pads, and surface electromyography sensors. Participants received electrical stimulation through electrode adhesive pads placed on both proximal and distal gastrocnemius muscles using a bioelectric stimulation technology® (BEST) micro-current platform (Tennant Biomodulator®). E-Stim was active in the intervention group and nonfunctional in the...
Dyani Lewis Spinal-cord injuries can be partially healed by remodelling of certain neurons.Credit: Steve Gschmeissner/SPL Neuroscientists have identified the nerve cells responsible for helping paralysed people to walk again, opening up the possibility of targeted therapies that could benefit a wider range of people with spinal-cord injuries. Severe spinal-cord injuries can disrupt the connection between...
UNIVERSITY OF PITTSBURGH VIDEO: ELECTRICAL STIMULATION OF THE NERVE ROOTS SPROUTING FROM THE SPINAL CORD TOWARD THE MUSCLES OF THE ARM AND HAND IMPROVES IMPROVED PRECISION, FORCE AND RANGE OF MOVEMENT OF ANIMALS WITH CERVICAL SPINAL CORD INJURY. view more CREDIT: MARCO CAPOGROSSO, UNIVERSITY OF PITTSBURGH PITTSBURGH, June 30, 2022 – Electrical stimulation of surviving nerves of the...
by Duke University The ASCENT tool models how nerves can respond to electrical stimulation from custom electrodes. Nerve fibers appear in red and blue, and the custom electrodes appear in gray. The bottom graphic shows how the nerves appear when they are activated. Credit: Eric Musselman, Duke University Biomedical engineers at Duke University have developed an...
by DGIST (Daegu Gyeongbuk Institute of Science and Technology) Synaptic remapping by electrical stimulation after stroke. (a) The connection between pre-and postsynaptic neurons are rebuilt by stroke and electrical stimulation. After stroke newly made connections are strengthened by electrical stimulation. (b) Incoming EPSP from presynaptic neurons and additional potential provided by STES induces a postsynaptic...
OCTOBER 18TH, 2019 ALICE FERNGEXCLUSIVE, NEUROLOGY, PSYCHIATRY, SPORTS MEDICINE We previously interviewed Humm, a San Francisco-based neuroscience company, when they had first released their Edge headset – an electrical stimulation device that helped users by boosting their working memory. Humm is focused on helping people continue to learn and grow throughout their lives. The idea behind their innovations is that through stimulation of...
