Chemical synapses and electrical synapses networks of roundworm

C.Elegans networks consist of the chemical synapses network and the electrical synapses network of the roundworm, where each of 279 nodes represents a neuron and each edge represents the intensity of synapses connections between two neurons.

Usage

data(C.Elegans)

Format

An object of class list of length 2.

Details

Two networks are weighted and directed graphs with self-loops. There are 2194 and 1031 edges in two graphs respectively and the empirical Pearson's correlation between two graphs is 0.17. Two networks are stored in a list in the form of igraph objects, where the first network in the list is the chemical synapses network and the other one is the electrical synapses network.
