Ritualistic displays of aggressive intent are important social signals, often obviating physically dangerous engagement. To date, however, brain regions mediating such behaviors are not established. Here we used male Anolis carolinensis together with an in vivo 14C-2-deoxyglucose method to determine patterns of brain activation during elicitation of this animal's dominance displays vs. other behaviors. By patching one eye regional brain activation in the hemisphere receiving display-evocative… 

Brain Mediation of Anolis Social Dominance Displays

Here, 3H-sumatriptan binding at sites similar to mammalian 5-HT1B/D receptors was significantly higher in forebrain regions of submissive anoles than in dominant cagemates; this receptor site seemed pharmacologically more like a 5- HT1B than a 5,HT1D receptor.

Dominant and subordinate males produce neuroendocrine stress responses during aggressive social interaction. In addition, stress responsiveness has both acute and chronic temporal components. A

Behavioural persistence during an agonistic encounter differentiates winners from losers in green anole lizards

The results indicate that behavioural display patterns during an initial display contest predict the outcome of the interaction, with the amount of display behaviour being the best predictor of whether a male will win or lose the contest and hence become dominant or subordinate.

Interactions between the neural regulation of stress and aggression

The pattern of neurochemical and hormonal events stimulated by social interaction make it clear that subtle differences in this pattern of response distinguish social rank, and the neurotransmitter serotonin appears to play the most important role for inhibitory regulation of aggressive interactions.

The results suggest that the most conspicuous visual display is the tail-flick, followed by the push-up body rock, and the slow arm wave is the least conspicuous, and this relationship is robust across the full range of environmental wind conditions.

Behavioral Diversity and Neurochemical Plasticity: Selection of Stress Coping Strategies That Define Social Status

A unique model for social stress in the lizard Anolis carolinensis is discussed, which has characteristics amenable to an investigation of individual differences in behavioral responses via central and sympathetic neurochemical adaptation.

Fear in the Animal and Human Brain

The chapter explains how the amygdala, which is said to operate under the “better safe than sorry principle,” tends to over-react to ambiguous stimuli as if they are threats, and therefore, produces fear even when something may not actually pose a threat of harm.

Arginine vasotocin, steroid hormones and social behavior in the green anole lizard (Anolis carolinensis)

It is found that AVT tended to reduce aggressive behavior as has been reported for other territorial species, and a role for AVT in the regulation of reptile social behavior is supported.

Distribution of FABP7 in Neural Tissue of Socially Defeated Adult Anolis Carolinensis

This thesis is presenting this thesis as partial fulfillment of the requirements for an advanced degree from Georgia State University, and the library of the university will make it available for inspection and circulation in accordance with its regulations governing materials of this type.

Serotonin-induced brain glycogenolysis in rainbow trout (Oncorhynchus mykiss)

It is found that 5-HT is involved in the modulation of brain glycogen homeostasis in the rainbow trout, causing a glycogenolytic effect when fish are in a normoglycemic or hypoglycemic state, but not when they is in a hyperglycemic state.
