Frequently Asked Questions (FAQ)

What numerical aperture is compatible with FP3001 and FP3002?

For best results, we recommend .37NA, which matches the optical components in the systems.

Can I synchronize fiber photometry data with my existing behavior hardware?

There are a variety of options for synchronizing fiber photometry recordings with behavior hardware. The system includes 2 digital inputs and outputs that can send or receive 5v TTL pulses for ultra-precise timestamp alignment. Behavior cameras and custom Arduino-based devices can also be synchronized through data acquisition software for simple synchronization.

How long should my FOC be?

The length of FOC that you choose will depend on the region you are targeting. We recommend choosing a length that is the same as or slightly (<.5mm) longer than the dorsal/ventral stereotaxic coordinate of your target. For example, if you are targeting a structure with a DV of –4.35, a 4.5mm fiber is appropriate. Excessive length will cause the ferrule to stick out further from the skull surface.

Are FOC reusable?

Generally, FOC are not reusable, as the chemicals capable of dissolving dental cement will also etch the glass core and damage them.

Are Ceramic split sleeves reusable?

Ceramic split sleeves can be reused indefinitely.
