Summary: Accurate population models are needed to build very large-scale neural models, but their derivation is difficult for realistic networks of neurons. I will discuss different mean field techniques employed to develop neuronal population models [1,2], with their advantaged and drawbacks. I will then introduce more recent developments in this field [3,4], where population models are today able to describe very accurately the collective behaviour of neuronal networks. Finally, I will discuss how these models are employed to explain microscopic mechanisms standing behind emergent phenomena measured at the mesoscopic scale in the brain, such as propagating waves in the cortex [5,6].
