Very interesting! This is not what I got from that article - and glancing at the cited ones.
I understood there was little correlation - I thought this means both ways. I'm not entirely sure how this can be asymmetrical? Is, perhaps, the activity the connectome predicts just a small subset (maybe just rare or even artifical?) of all potential activity patterns in a nervous system?
For the worm there's the additional problem that the field has been working with point neurons for decades, ignoring the fact that most neurons in C. elegans have a very clear axon separate from its dendrite. I'd like to see a cleaned up connectome where there are 4 synaptic connectivity matrices and not one (axo-dendritic, axon-axonic, etc.), and I fear I may have to do so myself.
Modeling a connectome while mixing axo-dendritic with axo-axonic synapses with a point-neuron model is only asking for trouble and confusion.
