Chemical anatomy of hydra nervous system using antibodies against hydra neuropeptides: a review

  • Osamu Koizumi
  • Nobuko Sato
  • Chieko Goto


Polyclonal antibodies against hydra neuropeptides allow us to visualize the hydra nerve net. Chemical anatomy of the hydra nerve net was archived by means of immunocytochemistry with various antibodies to hydra neuropeptides. Our goal is to describe the hydra nerve net both qualitatively and quantitatively. The present chemical anatomy results indicate (1) differences in peptide expression between ganglion cells and sensory cells, (2) large differences in neuropeptide expression between ectodermal nerve cells and endodermal nerve cells, and (3) the usefulness of quantitative chemical anatomy to analyze the entire nervous system of hydra.
