Topic: Courtship behaviour

Animals exhibit extraordinary variation in their behavior, yet little is known about the neural mechanisms that generate this diversity. My lab has been taking advantage of the rapid diversification of male courtship behaviors in Drosophila to glean insight into how evolution shapes the nervous system to generate species-specific behaviors. By translating neurogenetic tools from D. melanogaster to closely related Drosophila species, we have begun to directly compare the homologous neural circuits and pinpoint sites of adaptive change. Across species, P1 neurons serve as a conserved node in reg

For many animals, the sense of olfaction plays a major role in controlling sexual behaviors. Olfaction helps animals to detect mates, discriminate their status, and ultimately, decide on their behavioral output such as courtship behavior or aggression. Specific pheromone cues and receptors have provided a useful model to study how sensory inputs are converted into certain behavioral outputs. With the aid of recent advances in tools to record and manipulate genetically defined neurons, our understanding of the neural basis of sexual and social behavior has expanded substantially. I will discuss

For social animals, successfully communicating with others is essential for interactions and survival. My research aims to answer a central question on the neuronal basis of this ability, from the perspective of the listener: how do our brains enable us to communicate with each other? My work develops nonhuman animal models to study the behavioural and neuronal mechanisms underlying the perception of vocal patterns. I will start by providing an overview of my past research characterizing the neuronal-level substrates of voice processing along the primate temporal lobe. I will then focus on my

Courtship behavior is an innate model for many types of brain computations including sensory detection, learning and memory, and internal state modulation. Despite the robustness of the behavior, we have little understanding of the underlying neural circuits and mechanisms. The Stowers’ lab is leveraging the ability of specialized olfactory cues, pheromones, to specifically activate and therefore identify and study courtship circuits in the mouse. We are interested in identifying general circuit principles (specific brain nodes and information flow) that are common to all individuals, in order
