A unique neurogenomic state emerges after aggressive confrontations in males of the fish Betta splendens

چکیده
• Changes in brain gene expression are accordance with changes behavior across the fighting process males Betta splendens. Brain-transcriptomic synchronization between two opponents within a pair during gradually lose after fighting. A basal neurogenomic state emerges as an energy-saving strategy among all individuals Long-term memory genes and autism-risk exert higher effect on loser than winner. Territorial defense involves frequent aggressive confrontations competitors, but little is known about how brain-transcriptomic profiles change competing for territory establishment. Our previous study elucidated that when fish splendens interact, transcriptomes their brains synchronize way reflects mutual assessment them at level. Here we aim to evaluate of immediately shifting social status (i.e., winner/loser has emerged) 30 min this shift. We showed certain unique different stages patterns transiently or persistently changed stages. These transcriptomic responses behavioral fight. Strikingly, specificity was lost ceased, leading emergence which were reduced minimum consistent individuals. This shares common characteristics hibernation animals adopt minimize metabolic rates save energy. Interestingly, related metabolism, autism spectrum disorder, long-term still differentiated losers from winners. Together, system using male B. provides promising platform investigating states aggression vertebrates.

Metabolic Costs of Aggressive Behaviour in the Siamese Fighting Fish, Betta splendens
Aggressive conflicts between males are often resolved by means of multiple ritualized agonistic displays without damaging escalation. Apparently, in such cases by using those displays opponents exchange important motivational and physical information on which they base a decision to stay or leave the interaction. In the Siamese fighting fish, the time spent spreading the dorsal fin and erecting...

ETTA SPLENDENS more commonly known as the Siamese fighting fish has B been popular in aquariums of western Europe and America for over 35 years. Its domestication and consequent inbreeding antedates the introduction into the West by 60 or 70 years. Selection for pugnacity, long fins (see Figure l ) , and bright colors over this long period has produced a number of phenotypes, none of which is v...

The neuromodulator serotonin is an important regulator of aggressive behavior in vertebrates. Experimentally increasing synaptic levels of serotonin with fluoxetine, a selective serotonin reuptake inhibitor, has been shown to reliably decrease the expression of aggressive behavior. Here, we describe a method by which fluoxetine can be noninvasively administered to male Betta splendens (an attra...
