Armin seeks to understand the nervous system computations underlying animal decision-making. His work focuses on the larval zebrafish, a small and almost perfectly translucent vertebrate with a brain similar to ours. Zebrafish have a rich and innately present behavioral repertoire and are amenable to genetic modifications. These features allow Armin’s group to combine precise tracking experiments, cognitive algorithmic modeling, whole-brain activity imaging, genomic sequencing, and targeted circuit manipulations, to in detail dissect the neural basis of decision-making.
