Status-Dependent Vasotocin Modulation of Dominance and Subordination in the Weakly Electric Fish Gymnotus omarorum.
Rossana Perrone,Ana Silva +1 more
TL;DR: This study contributes a clear example of status-dependent AVT modulation of agonistic behavior in teleosts, and reveals distinctive activation patterns of the AVT system between dominants and subordinates.
Journal ArticleDOI
Environmental, seasonal, and social modulations of basal activity in a weakly electric fish.
TL;DR: Novel data is provided on the complex interactions between environment, reproductive cycle, social behavior, and electromotor output in an advantageous model of the vertebrate central nervous system of Brachyhypopomus pinnicaudatus.
Journal ArticleDOI
Non-sex-biased Dominance in a Sexually Monomorphic Electric Fish: Fight Structure and Submissive Electric Signalling
TL;DR: It is confirmed that body size is the best RHP proxy in non-breeding intra- and intersexual contests of this monomorphic species and demonstrated a sequential pattern of submissive signalling by means of two different electric displays.
Journal ArticleDOI
Neuromodulation of the agonistic behavior in two species of weakly electric fish that display different types of aggression.
TL;DR: It is demonstrated that a distinct spatio-temporal pattern of activation of the social behavior network characterizes each type of aggression by exploring its modulation by both the 5-HT and AVT systems.
Journal ArticleDOI
Social electric signals in freely moving dyads of Brachyhypopomus pinnicaudatus.
TL;DR: The data suggest the existence of a sophisticated electric dialog during reproductive and aggressive interaction whose precise timing and behavioral significance are being investigated.
