Significance
For: beginner
The problem
Traditional invasive arrays require open craniotomy and face progressive foreign-body immune responses and glial scarring.
Method
Stentrode electrode lattice implanted through the jugular vein into the superior sagittal sinus adjacent to primary motor cortex.
Result
Maintained signal stability and daily digital communication / switch control across 12+ months in human participants with zero vessel occlusion.
Why it matters
Establishes endovascular neuro-interventions as a viable, minimally invasive route for chronic motor prostheses.
Limitations
Bandwidth and single-unit resolution are lower than intracortical microelectrode arrays like Utah Array or Neuralink.
