Cortical neurons are well approximated by a deep neural network (DNN) with 5–8 layers This is a link to the abstract so you don't get to find out the width of these networks. But given that neural networks are universal approximators, it seems to me that all that's being said is a neuron is a very complicated thing. And so the phrasing seems to give an unjustified impression you still best think of a biological neural network as just a larger artificial neural network.
