Parkinson’s Disease Propagates From Gut Cells Via The Vagus Nerve

A new study offers a more accurate model in which to test treatments that could prevent or halt Parkinson’s disease progression. In experiments in mice, Johns Hopkins Medicine researchers report they found additional evidence that Parkinson’s disease originates among cells in the gut and travels up the body’s neurons to the brain. “These findings provide […]

Vagal Gut-brain Axis Stimulation Produces Reward Behaviors

A novel gut-to-brain neural circuit establishes the vagus nerve as an essential component of the brain system that regulates reward and motivation, research from the Icahn School of Medicine at Mount Sinai indicates. The study provides a concrete link between visceral organs and brain function, especially in regards to reward, and may help to inform […]

Vagus Nerve Stimulation Enhances Post-stroke Rehabilitative Training

Vagus nerve stimulation, paired with a physical therapy task, doubles long-term recovery rate relative to current therapy methods, new rodent research indicates. The study, from researchers at The University of Texas at Dallas, demonstrates a method to accelerate motor skill recovery after a stroke by helping the brain reorganize itself more quickly. A clinical trial […]

Vagus Nerve Stimulation Implant Adds Inhibiting Signal

Vagus nerve stimulation, a therapy for serious chronic inflammatory diseases, is getting a way to keep what helps, while blocking what harms. The innovation by Georgia Tech researchers of adding an inhibiting signal could increase the clinical efficacy and therapeutic benefit of existing treatments. Forms of vagus nerve stimulation treatment have already been successfully tested […]
