Fifty years of study of the nervous system and behavior of crayfish have revealed neural
circuits for movements that are similar to those seen during formation of a dominance …

The abdominal nervous system of the crayfish contains six serially homologous ganglia,
each containing approximately 650 neurones. No two ganglia are identical, and the ganglia …

The interneurons that underlie abdominal flexion and extension behaviors in crustaceans
were among the first to be called command neurons. They fit the original operational …

In crustaceans, as in other social animals, aggression is used to gain and control access to
resources, including shelter, food, and mate choice. The high “resourceholding potential” of …

Stimulation of small bundles of axons in abdominal connectives of the lobster (Homarus
americanus), as well as application of two monoamines, octopamine and serotonin, can …

1. We have identified and characterized a family of several pairs of neurons in the cerebral
ganglion of Aplysia brasiliana that are capable of inducing, maintaining, or modulating a …

Abdominal ganglia of crayfish contain identifiable neuropils, commissures, longitudinal
tracts, and vertical tracts. To determine the functional significance of this ganglionic …

Nine identified interneurons that originate in the 6th abdominal ganglion were studied with
intracellular techniques while activating the receptors presynaptic to them with coherent …

Intracellular recording and dye injection was used to investigate the flexion‐evoking
interneurons in the isolated abdominal nerve cord of the crayfish, Procambarus clarkii. The …

Crustacean cardioactive peptide‐immunoreactive neurons have been mapped in
wholemount preparations and sections of the ventral nervous system of the crayfish Astacus …
