Abstract and Keywords

This article examines the use of invertebrates to investigate the genetic and physiological mechanisms that regulate social behavior. A central goal in behavioral neuroscience is to understand how genes encode behavior and how environmental factors influence the expression of these relevant genes. In pursuit of this goal, many scientists who study behavior use a combined ecological, molecular, genomic, and physiological approach. This article discusses the distinct strengths of an approach, species, or finding in the context of two related but unique social behaviors: aggregation and aggression. It considers the genes that control aggregation and aggression by drawing on insights from C. elegans and Drosophila, respectively. It also describes the neurotransmitters, neuromodulators, and receptors that regulate aggregation and aggression.

Keywords: invertebrates, social behavior, genes, aggregation, aggression, C. elegans, neurotransmitters, Drosophila, neuromodulators, receptors
