The role of serotonin in fly aggression: a simplified system to investigate a complex behavior
MetadataShow full item record
The use of aggressive behavior for the obtainment of food resources, territory, and reproductive mates is ubiquitous across animal taxa. The appropriate perception and performance of this highly conserved behavior towards conspecifics is critical for individual fitness and thus a product of evolutionary selection in species as diverse as mammals to insects. The serotonergic (5-HT) system, in particular, is a well-known neurochemical modulator of aggression in both vertebrates and invertebrates. However, the underlying proximate mechanisms of 5-HT receptor subtypes and their role in mediating ...
