Research work
In our lab we study neural networks underlying different behaviors, such as navigation, decision making and sensory processing. We investigate the dynamics and connectivity patterns of these networks, with a focus on the flexibility of neural networks and how it supports these complex processes. We study these networks in zebrafish larvae and juvenile, a small transparent vertebrate ideally suited to investigate distributed networks.
