The human brain is an organ of extreme complexity, the object of ultimate intellectual egocentrism, and a source of endless scientific challenges. Its intricate folded shape and complicated internal wiring have fascinated generations of scientists but still raise fundamental questions. How do brain convolutions emerge? How is the brain geometry related to its function? How are different parts of the brain connected to each other? What is special about the human brain? In this talk, I will show that by using geometry, scaling laws, modelling, and network topology, we can uncover some of the basic principles at work in the shaping of our brains. ========== The London Mathematical Society has, since 1865, been the UK's learned society for the advancement, dissemination and promotion of mathematical knowledge. Our mission is to advance mathematics through our members and the broader scientific community worldwide.
