I haven't read the paper and IANABiophysicist, but I have read that fuzzy-logic-like non-linear functions can actually be computed at the junctions where dendrite branches come together... and there are quite a lot of those per neuron. Of course many components of a neuron behave non-linearly to some degree. So yes, quite a lot like a whole ANN.
