Advancing neuromodulation research

Originally developed at the University of Michigan, NeuroNexus’ suite of commercialized technologies has, for over a decade, led to hundreds of publications from research labs all around the world. Our products include conventional and high-density leads, recording and stimulation systems, and software for data analytics.

Our products have been used in a wide variety of animal models from fruit fly to rodent to non-human primates. NeuroNexus is currently working to make our state-of-the-art technologies and systems available for human clinical research.

NeuroNexus is the global leader in neuroscience research. Now expanding into clinical research.

NeuroNexus offers a custom lead design service that provides unique access to a virtually unlimited design space. Almost any feature of a lead can be tailored to suit your application - and all it takes to get started is a sketch.

Each custom lead includes:

• Consultation with our engineering team to validate feasibility of your proposed design

• Translation of your design into a CAD layout

• Formal design review with our technical team

• State-of-the-art microfabrication of your design

• Packaging and testing of the fabricated devices

• Ability to imprint text (such as your name) on the lead
