The “Synergistic Core” of the Human Brain?

A new preprint makes a bold claim: that “synergistic interactions are the fundamental drivers of complex human cognition”

What does this mean, and what are the implications for neuroscience?

Authors Andrea I. Luppi et al. of the University of Cambridge study a new aspect of brain organization: synergy between brain regions. Some networks of the brain are more synergistic than others, and synergistic networks tend to be involved in complex cognition.

So what is synergy? Luppi et al. define it in accordance with the mathematical framework called MMI-PID. Two variables are said to have a synergistic interaction to the extent that the future state of both variables can only be predicted from the past state of both variables together, not from the past state of either variable alone.

As an example, consider two balls moving in space. The two balls might or might not collide. If we know the current
