R2 System
Recover your probes
We make recoverable metal microdrives for chronic silicon-probe recordings in freely moving and head-fixed experiments. They work with the probes you already use and can let you use them 3x more often.
REMY
Head-fixed behavior for rats
A validated head fixation system for behavioral experiments with moving rats. Reliable head-fixation of rats running on is treadmills not easy. REMY aims to change that.

Hardware
We build custom projects for your specific needs. If possible, we publish them as open source hardware for other labs to use.

Starting new with recoverable silicon probe implants or want to get experiments with head-fixed rats up and running? Here's how to:
Everyone hates going back and forth with suppliers to find out prices and get a quote. That's why we made it instant and transparent. Just add the parts you need to your quote basket, and get a PO-ready quote in your inbox a few seconds later.
- Transparent pricing
- Instant quotes
- Validated system used by over 100 labs
- Compatible with most silicon probes
Not sure how many implants you might need for your experiments? Doubting whether it's worth it? Enter animals, batch size and probe cost and get a suggestion for exactly which R2 hardware you need and what recovering your probes can save you.
- Right products & quantities
- Net saving vs. re-ordering probes for each animal
- Add the whole bundle to a quote
- No email required (we also hate those "extra features" on websites that make you sign up for 20 newsletters before you can see the result)
Applying for a grant and want to use the R2 system from the start? Want to make sure you always have the right implants for your experiments? Let us help to tailor things to your needs! For example:
- Custom hardware development
- Collaboration on grant / budget development
- Support with experiment planning
- Collaboration in scientific projects
3Dneuro’s R2 drives have allowed our lab to establish reliable chronic and recyclable Neuropixels recordings in freely moving rats performing behavioral tasks. We have used them for several years across a range of brain regions, including multiple areas of the frontal cortex and subcortical structures such as the dorsal striatum. Although many drive designs are now available, the R2 system remains our favourite because of its ease of use, robustness, and ability to maintain high-quality recordings for several months. We have also tested the new R2rail and holder and were impressed by this variant. Together, they address an important practical challenge in consistent alignment between the probe and the drive.

- Probe recovery success
- Probe recovery has generally been successful. However, we have not yet reused the probes consistently because cleaning them thoroughly after explantation remains challenging.
