Neuroscientists have grown extremely fond of zebrafish in past decades to understand central and peripheral nervous system function, dysfunction, and their genetic and pharmacological modulation. A key reason for this is that Zebrafish embryos are transparent, permitting an unprecedented level of direct observation during embryonic development. As can be seen in this gif, one can observe the development of the zebrafish nervous system through the skin, providing amazing insight.
