* ''C. elegans'' don't have any histamine signaling natively. You can make animals that express histamine-gated chloride channels to chemogenetically inactivate channel expressing neurons when histamine is given exogenously. '''Look for a GABA<sub>A</sub>R His-Cl worm line. | * ''C. elegans'' don't have any histamine signaling natively.
