PyOKR: A Semi-Automated Method for Quantifying Optokinetic Reflex Tracking Ability

We're interested in understanding the mechanisms that regulate visual motion processing behaviors, such as the optokinetic reflex. We developed PyOKR as an accessible and uniform platform to reproducibly quantify a wide range of visual responses under various conditions to further our understanding of these behaviors. There's no unified method within the field to quantify optokinetic reflex responses, which can cause disparities when comparing data between laboratories.

We hope that PyOKR can help standardize how these data are analyzed to provide an accessible, unbiased, and robust tool to study these visual responses. Existing methods usually differ between laboratories, and are often custom designed for their specific needs. PyOKR offers a unified method that is user-friendly, accessible, and adaptable to different experimental designs.

With a combination of automated analysis and user input, it can generate unbiased, accurate results to answer the user's desired questions. The use of our new PyOKR analysis method will facilitate the study of visual response behaviors in many contexts, such as genetic or pharmacological manipulation. Because of its accessibility and adaptability, it'll allow researchers to efficiently quantify responses to answer new questions about how visual circuits form and function.

With the help of PyOKR, we hope to identify new mechanisms that regulate the development of the direction selective circuits that drive optokinetic reflexes. Using this approach with neuro circuit perturbation will continue to help us study the development and function of these critical visual systems.
