Wireless Device Might Wring Out Ringing in the Ears

Scientists prove vagus-nerve stimulation can reverse tinnitus in rats and plan to apply wireless stimulators to humans

4 min read

19 January 2011—Scientists say they can cure tinnitus—persistent ringing in the ears—by pairing certain tones with stimulation of a nerve in the neck.

Tinnitus is caused by noise damage to the sensory cells in the inner ear, or cochlea. This damage results in changes to the organization of the brain’s auditory cortex, a region that contains a "frequency map" of sounds. Damage to the inner ear causes a portion of this map to take over other parts of the cortex, causing the ringing.

A New Treatment for Arthritis: Vagus-Nerve Stimulation

Studies will soon show whether electroceuticals outperform pharmaceuticals

Monique Robroek once had such crippling arthritis that, even with the best available medications, she struggled to walk across a room. But thanks to an electronic implant fitted under her skin, she managed to wean herself off all her drugs and live pain-free for nearly a decade—until recently, when a viral illness made her rheumatoid arthritis (RA) flare up again.

This article is part of our special report Top Tech 2023.

Robroek’s long remission is “very impressive” and rare among patients with RA, says her doctor Frieda Koopman, a rheumatologist at Amsterdam UMC, in the Netherlands. Robroek’s experience highlights the immense potential of so-called bioelectronic medicine, also known as electroceuticals, an emerging field of treatment for diseases that have traditionally been managed with pharmaceuticals alone.
