Brain wiring linked to genes

The first evidence of a genetic effect on how 'cost-efficient' our brain network wiring is - shedding light on some of the brain's make up - has been released.

The first evidence of a genetic effect on how 'cost-efficient' our brain network wiring is - shedding light on some of the brain's make up - was recently published in the Journal of Neuroscience.

"The brain tries to maximise 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."
