Explore the fascinating science behind how brain wiring shapes individual identity in this 43-minute lecture from The Royal Institution. Delve into neuroscientist Kevin Mitchell's groundbreaking research on human diversity and individual differences stemming from brain development. Discover how variations in neural development link to adult psychology and behavior, and examine the potential impacts on personality, intelligence, and sexuality. Learn about early embryonic development, the genetic program for human brain formation, and the heritability of brain structural and functional connectivity. Investigate the role of intrinsic developmental variation, neuromodulators, and subjective experience in shaping our neural circuits. Gain insights into the complex interplay between genetics, brain development, and individual traits that make each person unique.
