C. elegans L1 Connectome Full (Witvliet 2020, Specimen 1, Unweighted)

Directed unweighted multigraph of all synaptic connections (chemical + electrical) in the L1 larval C. elegans. Each synapse is a separate edge. Contains self-loops (autapses via electrical junctions). No connection-type distinction (homogeneous).
