Serotonin and octopamine, injected into the circulation of freely moving lobsters and crayfish, produce opposite behavioral effects. Octopamine injection produces sustained extension of the limbs and abdomen; serotonin injection produces sustained flexion. Neurophysiological analyses show that these postures can be accounted for by opposing, coordinated effects of these amines on patterns of motoneuron activity recorded from the ventral nerve cord.

The effect of serotonin and octopamine on the optokinetic response of the crab Leptograpsus variegatus.

Experiments show that serotonin is most likely acting closer to the sensory input in the optokinetic system than octopamine when applied in low doses.

Although serotonin and octopamine modulate the excitability of the escape response, neither monoamine appears to significantly alter the rate at which this response habituates.

Serotonin Increases Flexion And Excitatory Junction Potential Amplitude While Octopamine Decreases Average Excitatory Junction Potential Amplitude In Crayfish

This study investigated the effects of serotonin and octopamine on excitatory junction potential amplitude (EJP) by stimulating the fast extensor muscles of the crayfish abdomen by injecting the amines into the hemolymph at the abdominal thoracic junction.

Effects of octopamine, dopamine, and serotonin on production of flight motor output by thoracic ganglia of Manduca sexta.

It is demonstrated that dopamine, octopamine, and serotonin have different effects on motor output in Manduca and suggested that these amines are involved in initiating, maintaining and terminating flight behavior, respectively.

Serotonin and octopamine in the nematode Caenorhabditis elegans.

Exogenous serotonin and octopamine elicit specific and opposite behavioral responses in Caenorhabditis elegans, suggesting that these compounds function physiologically as antagonists.

Serotonin and octopamine elicit stereotypical agonistic behaviors in the squat lobster Munida quadrispina (Anomura, Galatheidae)

The social behaviors and reactions to injected serotonin and octopamine of M. quadrispina differ from those of lobsters and crayfish, indicating that interspecific differences in neuromodulation of behavior and motor output exist, and have implications for the understanding of aminergic modulation of aggression and the evolution of am inergic modulation in crustaceans.

Cellular mechanisms for modulation of posture by octopamine and serotonin in the lobster

The results suggest that octopamine and serotonin have dual effects on posture: within the central nervous system, they act specifically to generate coordinated motor patterns for flexion or extension; as circulating neurohormones, they acts nonspecifically to enhance the responses of exoskeletal muscles to motoneuronal activation.
