...Andrew N. Bubak; Michael J. Watt; Jazmine D. W. Yaeger; Kenneth J. Renner; John G. Swallow ABSTRACT Serotonin (5-HT) has largely been accepted to be inhibitory to vertebrate aggression, whereas an opposing stimulatory role has been proposed for invertebrates. Herein, we argue that critical gaps in...
