Wireless Optogenetics FAQs

Q: How long is the latency between a trigger pulse and the receiver output? What is the time resolution for pulses?
A: There is a 240 µsecond latency for activating the original pulse receiver, 25 ms for the continuous receivers, and 2050 µs for the new 2 channel pulse re...

Q: How many animals can one Remote Control stimulate at once?
A: The emitters are limited only by range and line of sight, and will pulse all of the receivers that can “see” an emitter. We offer a wide beam emitter tha...

Q: How deep can the fiber optics be implanted?
A: Teleopto fiber optics can be made to any length you specify. The acrylic fiber is flexible, so a guide cannula may be appropriate for deep implants in la...

Q: What wavelength do the IR emitters and receivers use? Can the emitters be used to transmit signals through the plastic walls of a chamber?
A: 940nm. Polycarbonate is generally transparent at this wavelength: the signal can pass through several standard transparent mouse home cages so long as th...

Q: Does the clip type emitter have to be used with a Telehub? Does the wide area emitter have to be plugged directly into the remote control?
A: Both emitter types can either be plugged directly into the remote or via the Telehub.

Q: What if I need more light power?
A: We offer custom high power receivers. A standard 1 gram pulse receiver coupled to a blue LED with a 500µm diameter fiber optic can output 13 mW;  custom ...

Q: How do I protect the 3 pin connector for the LED after implantation?
A: A drop of hot glue covering the pins and the top surface of the implant will help protect the pins. If you have difficulty removing the hot glue: You can...

Q: Can Teleopto be combined with electrophysiology headstages?
A: Yes. Users sometimes see stimulation artifacts at the onset of optical stimulation, but the amplitude is smaller than the artifacts seen with conventiona...
