35 Katja Heuer brain. It’s very important to take that into consideration more and more. It gives us a different perspective for looking across evolution to understand variability at a larger scale. You are obviously very passionate about the subject. What have you discovered that excites you the most? We have been studying brain development and brain folding using real data and computer simulations. When we looked at primate species, it was the first time that we could clearly see species that were genetically further apart, and yet, their folding patterns were so similar. We developed a method that we call fold graphs. It’s the first time that we tried to quantify how folding patterns look, how can we compare folding patterns – not the number of the folds but the organization of the folds across different brains within one species, within humans or across species. We looked across species, and Does your study influence the way that you relate to your own brain? Do you apply your observations in your life? I never thought about it that way. I find it super interesting and encouraging when you look at brain plasticity. People OHBM Hackathon in Rome Standing on shoulders of giants what we found there is that even if gene � cally they are more similar they may have di ff erent folding pa � erns just because their brain volume is di ff erent. It was very interes � ng when we found that out. We also developed a method to match the brains of di ff erent species. And when we match them based on volume similarity, jumping between the branches in the species tree, we get a super smooth trajectory of evolu � onary expansion. It's fascina � ng!
