Neural circuit mechanisms for visual processing and behavior in zebrafish


Research Summary

Animals generate a range of behaviors depending on visual information that they receive from their outside world. Using zebrafish as a model, our lab studies the neural circuit mechanisms by which visual inputs produce goal-directed behavioral outputs. In particular, we aim to understand the roles of genetically defined neuron types and their circuit connectivity underlying the visually guided behaviors. The approaches that our lab uses include behavioral, genetic and optical techniques, as well as quantitative data analyses.

(B) Calcium imaging and quantitative analysis reveal the activity pattern of multiple neuron types in a brain region (e.g. pretectum) involved in the visual processing. (C) Predicted wiring diagram of the whole-field motion processing circuit in the pretectum.
