70% of all info within cortical regions in the brain passes through only 20% of its regions’ neurons. These high-traffic “hub neurons” could play a role in understanding brain health since this sort of highly efficient network – in which a small number of neurons are more essential to brain function – is also more vulnerable to disruption. That’s because relatively small breakages can cause the whole system to “go down”...
