NeuroNexus offers a wide range of products to support optogenetics research. Our optogenetics line includes optoelectrodes, implantable fibers, light source systems, and accessories. If you are new to the field of optogenetics, we also offer smartly bundled optogenetics packages with the equipment you need to get started.
OPTOELECTRODE ARRAY DESIGNS
Any Standard electrode array can be configured as an optoelectrode to enable concurrent optical
stimulation and neural recording. An optical fiber (105 μm diameter) is placed on the top of the shank, and terminates 200 μm above the proximal site (distance can be customized on request). Multi-shank electrode arrays can be configured as optoelectrodes, but have limitations on fiber placement. Contact us for more information.
PROBE PACKAGE AND HEADSTAG E I N T E R FACE
NeuroNexus optoelectrodes use packages similar to our Standard probes. We recommend the OA series for acute experiments, and the OCM (Omnetics Nano) and OZ (Zif Clip™) series for chronic experiments.
