Modeling neural circuit dynamics in whole-brain imaging data of larval zebrafish
Recent experimental advances have made it possible to record activity of a large number of neurons (the information processing cells) simultaneously in behaving animals. Such data reveal unprecedented complexity and promise unique opportunities for understanding neural circuits dynamics across multiple brain areas via data-driven modeling. In this project, we will work with the whole-brain activity datasets of larval zebrafish, where essentially ALL the neurons in the brain are being recorded thanks to the transparency and small size of the animal. We will apply and adapt latest machine learning approaches to extract key biological information such as functional cell types and connectivity between neurons. Based on these results, we will build multi-scale models of neural circuits that link dynamics from single neurons to brain areas and to the behaviors of the animal.
