Light stimulation was generated by custom-written code in Igor software (Wavemetrics) and 4D Workshop 4 IDE (4D Systems) to control an LCD mask in front of a collimated LED (405 nm, Thorlabs) with a bandpass filter (BP 405, Thorlabs). The stimuli were projected onto the retina through the objective lens (XLUMPlanFL 20× 0.95 NA water-immersion, Olympus). Stimulus contrast varied between 100 – 300%, with the 300% stimulus intensity at ~25 × 103 photons s−1 μm−2 on a background intensity of ~6 × 103 photons s−1 μm−2. For the bar stimulus, the bar (400 × 400 μm) moved in one of eight evenly – spaced directions at a range of velocities between 0.03 – 1 mm s−1. The bullseye stimulus was configured as previously described6 (link). Each stimulus was repeated 3 – 5 times and responses were averaged.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
