The founders of neuroscience, as ranked by fecundity measured from the Neurotree database (normalization factor, γ = 1/2, see Methods).

Year refers to first year a degree was awarded to a trainee of this mentor. Generation (Gen) refers to the number mentorship steps back to the oldest common ancestor. Rankings for these individuals based on measures with alternative (Alt) normalization factors appear in the columns at right. At the extremes, γ = 1 weighs all offspring equally, regardless of generation, and γ = 1/10 counts primarily the number of direct trainees and gives very little weight to later generations.
