What is Connectome: How the Brain's Wiring Makes Us Who We Are about?

Sebastian Seung, a dynamic young professor at MIT, is at the forefront of a revolution in neuroscience. He believes that our identity lies not in our genes, but in the connections between our brain cells - our own particular wiring.

The Connectome: The Brain’s Wiring Diagram

Seung introduces the concept of the connectome, the complete map of neural connections in the brain. Unlike the genome, which is relatively static, the connectome is dynamic and changes with experience. This wiring diagram is so complex that even mapping the connections in a cubic millimeter of brain tissue is an immense challenge. The connectome underlies everything from perception to personality, suggesting that who we are is encoded not just in our genes, but in the ever-changing links between our neurons.

Nature, Nurture, and Neural Connections

The book challenges the traditional nature-versus-nurture debate by showing how both genes and experience shape the connectome. Genes lay down the basic structure, but life experiences continually rewire connections. This means that learning, memory, trauma, and healing are all processes of physical change in the brain’s wiring, making the connectome a living record of our personal history.
