title: Serotonin-like immunoreactivity of giant olfactory interneurons in the crayfish brain.
abstract: A pair of large interneurons on each side of the brain of the crayfish, Orconectes virilis, react with an antibody raised against serotonin. Both neurons of each pair branch extensively in the olfactory lobe and terminate among the axons of the olfactory globular tract.
