How do networks of interconnected nerve cells give rise to computations? In my PhD, I combined anatomical and electrophysiological analyses of the same synapses in the neocortex to understand more about how the communication between neurons at these tiny contact points works. In my postdoc at Harvard, I am using similar techniques to relate structure and function of the neuronal circuits in the hindbrain of the zebrafish to understand how particular computational algorithms could be implemented in these neuronal networks.
