Two layers of the neuronal network of C. elegans. (a) An example of forward locomotion induced by two layers of the neuronal network of the worm (image credit http://www.connectomeengine.com/). The first layer (b): connectome of C. elegans, consisting of 297 somatic neurons, 6393 chemical synapses and 890 gap junctions. The connectome shows (i) the chemical synapses between neurons and (ii) the gap junctions. The second layer (c): neural dynamics modelled by differential equations. Here, we show voltage oscillations of the motor VB group. Combining the two layers we achieve the dynome, a dynamically evolving network, which is the foundation for constructing the PGM.
