Researchers from imec and the Feinstein Institutes for Medical Research developed an ASIC to enhance control over the activation of the vagus nerve
Cuffs around the nerve are used to deliver slightly different sinusoidal stimuli, creating a specific activation pattern. This new ASIC offers a more precise and energy efficient control over neural activation that can be used for treatment of depression and rheumatoid artritis
The ASIC is based on intermittent interferential current stimulation (i²CS): Cuffs around the nerve are used to deliver slightly different sinusoidal stimuli, creating a specific activation pattern. This pattern allows for more localized activation and improved control of the organ-specific fibers within the vagus nerve, significantly reducing the activation of non-targeted fibers and thus minimizing side effects in other organs.
