I want to know what makes us social. Why do we spend so much time with other people? Why are our actions and thoughts so influenced by other people? How are these social needs generated in the brain?
Zebrafish are small social animals that swim together in groups. Their brains are transparent, and we can use powerful microscopes to watch every single neuron while they behave. Therefore they are helping me understand how the brain generates these fundamental social drives that we share with all social animals.
