[Fridtjof Nansen as a neurobiologist]

Fridtjof Nansen (1861-1930) started his four-year research carrier in neurobiology at the Museum in Bergen in 1882. His PhD thesis from 1886 describes the structure of the nervous system in selected groups of invertebrates and in Amphioxus and the hagfish. For his time, he was a firm antireticularist and is still recognised as a forerunner of the emerging neurone doctrine of contiguity and no continuity between neurons in neural pathways.
