Figure 6. Historical influence of neuroscience researchers through mentorship.

A, Comparison of researcher generation, the number of mentorship steps back to a common ancestor, versus the year the researcher began mentoring, for the subset of researchers for which this information is available. Gray dots indicate individuals and the blue curve indicates the average year for each generation (r = 0.88). B, Fecundity index (the number of descendents per researcher normalized exponentially by the number of steps from that researcher) as a function of generation. Gray dots and blue curve plotted as in A. Green curve indicates the number of researchers per generation. C, Fecundity index and average number of new researchers per year for the subset of nodes with mentorship year data, plotted as in B.
