Ep 14 | What sea creatures can tell us about neuroscience

Most of what we know about neuroscience has been worked out from research on animals in the sea. One of those things is vision. Professor Justin Marshall talks about how important sea creatures are to our understanding of neuroscience, particularly vision. And Dr Fanny De Busserolles tells us what we can learn about vision from the creatures that inhabit the deep, dark depths of the oceans.
