NeuroNexus optoelectrodes enable concurrent optogenetic stimulation and high-resolution electrophysiology.
- A powerful tool – Optical fibers are laminated onto silicon probes to create an optoelectrode. Utilize a single fiber, or configure multiple fibers on a single probe (one fiber per electrode shank) to activate different opsins or target different brain areas.
- Options, options – Utilize any electrode array design and select from four different fiber types (and specify their termination locations on each shank) to create your ideal optoelectrode.
- Minimal tissue damage – Our smallest fiber option measures just 65 µm (outer diameter), for minimal impact on brain tissue.
- Controlled artifact – NeuroNexus optoelectrodes are engineered for minimal photoelectric artifacts.
Our new tapered fiber option (shown above) provides enhanced stimulation capabilities:
- Sub-micron fiber tip minimizes tissue damage and can be inserted further into the area of study
- Uniform light delivery across the tapered region for more homogenous and efficient stimulation
- Sub-sample the target region without probe movements with an OptogeniX Launching System
