  Data of White et al., 1986, with additional connectivity in the ventral cord from reannotation of original electron micrographs.
  Connectivity table available through WormAtlas.org: Connectivity Data-download [.xls]
  Number of chemical and gap junction (electrical) synapses for all neurons and motor neurons. Number of NMJ’s for all ventral cord motor neurons.
• Adult hermaphrodite and adult male Data of Cook et al., 2019, Jarrell et al., 2012, and updates. Emmons laboratory data.
  Complete chemical and gap junction connectivity between all neurons, between neurons and end organs (muscles, gonad, gut, hypodermis), and gap junctions between the muscle cells. Connection weights from number of synapses and synapse sizes. Skeleton diagrams and synapse lists for all neurons and muscles directly reconstructed from electron micrographs. Monadic or polyadic structure of each synapse is given. From a reanalysis of the electron micrographs of White et al., 1986 (adult hermaphrodite), Sulston et al., 1980 (male tail), and new electron micrographs, Cook et al., 2019 (male head).
