Rapid advances in the neural control of social behavior highlight role interconnected nodes engaged differential information processing to generate behavior. Many innate behaviors are essential reproductive fitness and therefore fundamentally different males females. Programming these differences occurs early development mammals, following gonadal differentiation copious androgen production by fetal testis during a critical period. Early-life programming its adult manifestation separate but yoked processes, yet how they linked is unknown. This review seeks that gap identifying four core mechanisms (epigenetics, cell death, circuit formation, hormonal modulation) could connect developmental changes mating aggression. We further propose unique behavior, adolescent play, bridges preweaning postpubertal brain engaging same networks underpinning aggressive behaviors.

Abstract Vocalizations communicate information indicative of behavioural state across divergent social contexts. Yet, how brain regions actively pattern the acoustic features context-specific vocal signals remains largely unexplored. The midbrain periaqueductal gray (PAG) is a major site for initiating vocalization among mammals, including primates. We show that PAG neurons in highly fish species ( Porichthys notatus ) are activated distinct patterns during agonistic versus courtship calling by males, with few co-activated non-vocal behaviour, foraging. Pharmacological manipulations within vocally active PAG, but not hindbrain, sites evoke network output to sonic muscles matching temporal and calls, showing balance inhibitory excitatory dynamics likely necessary patterning different call types. Collectively, these findings support hypothesis mammals share functionally comparable nodes some can influence structure signals.

Sexual selection research has been dominated by the notion that mate choice selects for most vigorous displays best reflect quality of courter. However, courtship are often temporally structured, containing different elements with varying degrees intensity and conspicuousness. For example, highly intense movements coupled more subtle components such as static postures or hiding displays. Here, we refer to display traits ‘coy’, they involve withholding information about maximal capabilities. We examine role variation within dynamic displays, discuss three hypotheses evolution coy behaviours. first review threat reduction hypothesis, which points sexual coercion autonomy important facets selection. then suggest in magnitude exploits pre-existing perceptual biases temporal contrast. Lastly, propose may leverage receivers' predispositions filling gaps information—the ‘curiosity bias’. Overall, our goal is draw attention magnitude, advocate possible scenarios regularly occur below performance maxima. Throughout, highlight novel directions empirical theoretical investigations.

This paper outlines my research path over three decades while providing a review on the role of fish sounds in mate choice and reproduction. It also intends to provide advice young scientists point toward future avenues this field research. An overview studies different model species shows that male mating acoustic signals can inform females competitors about their size (dominant frequency, amplitude, sound pulse rate modulation), body condition (calling activity rate), readiness rate, number pulses sound). At least with parental care, such as toadfishes, gobies, pomacentrids, calling seems be main driver reproductive success. Playback experiments ran restricted consistently revealed prefer vocal silent males select for higher rates. personal synthesis concludes suggestion increase knowledge signals, especially considering emerging use monitor aquatic environments due increasing threats, like noise pollution.

Across vertebrates, the midbrain periaqueductal gray (PAG) plays a critical role in social and vocal behavior. Dopaminergic neurotransmission also modulates these behaviors, dopaminergic innervation of PAG has been well documented. Nonetheless, potential dopamine shaping production at level is not understood. Here, we tested hypothesis that PAG, using well-characterized vertebrate model system for study communication, plainfin midshipman fish, Porichthys notatus. We found focal injections to rapidly reversibly inhibited triggered by stimulation known vocal-motor structures preoptic area / anterior hypothalamus. While output, it did alter behaviorally-relevant parameters this such as vocalization duration frequency. Dopamine-induced inhibition was prevented combined blockade D1- D2-like receptors but unaffected isolated either D1-receptors or D2-receptors. Our results suggest neuromodulation may inhibit natural behavior, courtship and/or agonistic contexts.

To humans, the diverse array of display behaviors that animals use for communication can easily seem peculiar or bizarre. While ample research delves into evolutionary principles shape these signals' effectiveness, little attention is paid to patterning signal design across taxa, particularly when it comes potential convergent evolution many elaborate behavioral displays. By taking a mechanistic perspective, we explore physiological and neurobiological mechanisms likely influence signals, emphasizing utilization pre-existing structures over novel adaptations. Central this investigation are concepts perceptual bias ritualization propose contribute convergence designs species. Perceptual explains phenomenon where systems receivers, used innate such as food predator recognition, select certain traits from signaler. Ritualization occurs with no functional role in co-opted through selection transformed new communicative signal. Importantly, susceptibility be brought about modifications occurred early time. In way, selective force causes co-option non-communicative involving systems. If bias, signal, increase highly conserved, then may see unrelated taxa facing similar sensory constraints.
