Better brain wiring linked to family genes

Better brain wiring linked to family genes: "He said how the brain’s network is organized has been a mystery to scientists for years. “The brain is an extraordinarily complex network of billions of nerve cells interconnected by trillions of fibres,” he said.

“The brain tries to maximize its bang-for-buck by striking a balance between making more connections to promote efficient communication and minimising the “cost” or amount of wiring required to make these connections. Our findings indicate that this balance, called ‘cost-efficiency’, has a strong genetic basis.”"
