Hypoactivity of the central dopaminergic system and autistic‐like behavior induced by a single early prenatal exposure to lipopolysaccharide
TLDR
The present findings demonstrate that prenatal LPS induced autism‐like effects and also a hypoactivation of the dopaminergic system. Expand
Non-sex-biased Dominance in a Sexually Monomorphic Electric Fish: Fight Structure and Submissive Electric Signalling
TLDR
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. Expand
Environmental and hormonal influences upon EOD waveform in gymnotiform pulse fish
TLDR
The hypothesis of temperature as the most important environmental cue for the onset of breeding in gymnotiform pulse fish of the temperate zone is supported by a clear temporal correlation that was observed in the wild between water temperature and sexual maturity, and the induction of gonadal maturation and sexual differences after acclimation at high temperature in the laboratory. Expand
Temperature sensitivity of the electric organ discharge waveform in Gymnotus carapo
TLDR
Interactions between temperature sensitivity of the electric organ discharge waveform and sexual maturity that might be crucial for reproduction are strongly suggested. Expand
Social electric signals in freely moving dyads of Brachyhypopomus pinnicaudatus
TLDR
The data suggest the existence of a sophisticated electric dialog during reproductive and aggressive interaction whose precise timing and behavioral significance are being investigated. Expand
Environmental complexity, seasonality and brain cell proliferation in a weakly electric fish, Brachyhypopomus gauderio
TLDR
The regionally and seasonally specific effect of social environment on cell proliferation suggests that addition of new cells to these nuclei may contribute to seasonal changes in electrocommunication behavior. Expand
Use of space as an indicator of social behavior and breeding systems in the gymnotiform electric fish Brachyhypopomus pinnicaudatus
TLDR
Data support the hypothesis that B. pinnicaudatus is polygynous or polygynandrous, and suggest that they use space in a manner consistent with exploded lek polygyny or iteroparous nest sitepolygynandry models. Expand
Tight hormonal phenotypic integration ensures honesty of the electric signal of male and female Brachyhypopomus gauderio
TLDR
Findings show that tight hormonal phenotypic integration between advertisement signal and other sex steroid-mediated traits renders the advertisement signal an honest indicator of a suite of reproductive traits. Expand
Environmental, seasonal, and social modulations of basal activity in a weakly electric fish
TLDR
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. Expand
Neuromodulation of the agonistic behavior in two species of weakly electric fish that display different types of aggression
TLDR
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. Expand
