Abstract We examined the effects of selective serotonin depletion and opioid ligands on social rank and related escape behavior of the cricket Gryllus bimaculatus. Establishment of social rank in a pair of males affected their escape reactions. Losers showed a lower and dominants a higher percentage of jumps in response to tactile cercal stimulation than before a fight. The serotonin-depleting drug α-methyltryptophan (AMTP) caused an activation of the escape reactivity in socially naive… Expand
Serotonin Mediates Depression of Aggression After Acute and Chronic Social Defeat Stress in a Model Insect
It is shown that blocking NO synthesis, just like ketanserin, affords resilience to multiple defeat stress, whereas blocking DA receptors, but not OA receptors, increases susceptibility, justlike fluoxetine. Expand
Serotonin precursor (5-hydroxytryptophan) causes substantial changes in the fighting behavior of male crickets, Gryllus bimaculatus
The results imply a significant role for serotonin in the regulation of social status-related behaviors in G. bimaculatus and indicate that some behavioral features of dominant male crickets are likely to be connected with the activation of the serotonergic system. Expand
The effect of opioids and their antagonists on the nocifensive response of Caenorhabditis elegans to noxious thermal stimuli
The effect of the opiate morphine and opioid neuropeptides Endomorphin 1 and 2 on the thermal avoidance (Tav) behavior of Caenorhabditis elegans is explored and Naloxone and CTOP were tested in combination with the drugs. Expand
Serotonergic modulation of social status-dependent behavioural plasticity of the crayfish avoidance reaction
It is found that the spike activities of both the abdominal postural and uropod motor neurones in response to sensory stimulation of the exopodite reversed in dominant animals, and when serotonin of more than 12.5 μM in concentration was applied the reverse of activity was observed. Expand
Effects of opiate ligands on intraspecific aggression in crickets
In the cricket Gryllus bimaculatus, the opiate antagonist naloxone caused a release of intraspecific aggression in male-losers and in females, and the agonist of mu-opiate receptors DAGO suppressed aggression inmale winners and decreased the percentage and duration of contact fights between previously isolated males. Expand
Octopamine and Experience-Dependent Modulation of Aggression in Crickets
Evidence is presented that a form of experience-dependent plasticity of aggression in crickets is mediated by octopamine, the invertebrate counterpart of noradrenaline, and that this effect is transitory and concurrent with the activation of the octopaminergic system that accompanies flight. Expand
Chronic alterations in serotonin function: dynamic neurochemical properties in agonistic behavior of the crayfish, Orconectes rusticus.
The present findings suggest 5,7-DHT is commonly used in behavioral pharmacology and its biochemical properties should be more thoroughly examined, and the apparent presence of powerful compensatory mechanisms indicates the need to adopt an increasingly dynamic view of the serotonergic bases of behavior like crayfish aggression.

Involvement of the opioid system in the hypokinetic state induced in cockroaches by a parasitoid wasp
The venom of A. compressa might contribute to the manipulation of cockroach behavior by affecting the opioid system, which is known to affect responsiveness to stimuli in insects. Expand
Social aggressiveness of female and subordinate male crickets is released by opiate receptor antagonist.
The results suggest that activity of the opioid system contributes to suppress aggression in subordinate males, as well as in females, during social contacts in cricket Gryllus bimaculatus. Expand
Neuromodulators and the Control of Aggression in Crickets
This chapter reviews work revealing that neuromodulators, primarily octopamine and nitric oxide, mediate such experience-dependent plasticity by modulating the relative behavioural thresholds to fight and to flee. Expand

The discussion attempts to delineate a role for 5-HT receptor subtype involvement in the modulation of aggression, with the restrictions faced with regard to the lack of specific serotonergic agonists and antagonists for certain receptor subtypes. Expand
The Effect of Social Experience on Serotonergic Modulation of the Escape Circuit of Crayfish
The neuromodulator serotonin has widespread effects in the nervous systems of many animals, often influencing aggression and dominance status. In crayfish, the effect of serotonin on the neuralExpand
Time-dependent effects of PCPA on social aggression in chicks
It is concluded that PCPA increased social aggression in birds, an effect that diminished as brain 5-HT levels recovered over a 1-week period. Expand
Serotonergic mechanisms promote dominance acquisition in adult male vervet monkeys
The sequence of the behavioral changes shown by the treated males as they acquired dominance status paralleled those seen in naturalistic conditions and strongly suggest that when hierarchical relationships are uncertain, serotonergic mechanisms may mediate the behaviors which permit a male to attain high dominance status.

Low CSF 5-HIAA concentrations and severe aggression and impaired impulse control in nonhuman primates.
Adolescent male rhesus macaques with low CSF 5-HIAA concentrations are at risk for 1) exhibiting more violent forms of aggressive behavior and 2) loss of impulse control as evidenced by greater risk taking during movement through the forest canopy. Expand

The results suggest that serotonergic CNS systems tonically regulate aggression in Anolis carolinesis, similar to that seen in many other species, and suggest that eyespot-darkening and aggressive responding can be pharmacologically dissociated, implicating serotonin in the regulation of this phenomenon.

Biogenic amines and aggression: experimental approaches in crustaceans.
The results demonstrate that agonistic behavior in crustaceans can be quantified and that the amines themselves have telling and subtle effects on the fighting behavior of animals, and that pharmacological interventions are possible that might allow a biochemical dissection of the underlying mechanisms involved in processes like decision making in these animals.

Spontaneous walking and escape running in response to wind puffs directed to the abdominal cerci were quantitatively studied in tethered walking crickets. 1. 1. An apparatus for optically recordingExpand
The interaction of dominance status and supplemental tryptophan on aggression in Gallus domesticus males
The results indicate that dominant and subordinate males show a differential sensitivity to the effects of dietary TRP, with TRP decreasing pecking more in dominant birds. Expand
Anatomical basis for interactions of enkephalins with other transmitters in the CNS of a snail
A comparison between anatomical observations and previous behavioral studies suggests that in gastropod molluscs cotransmission of enkephalins with classical transmitters may, at least partly, reflect synergism of these substances in the control of definite behavioral programs. Expand
