| Popis: | Bats are auditory specialists, processing acoustic signals to guide their behaviors, including prey tracking, navigation and communication. In this talk I will provide an overview of my work related to how bats analyze and process signals for action-selection; specifically prey tracking and background clutter segregation—work inspired by research from Jim Simmons’s lab. I will also give an overview of the line of research of my current lab, neural mechanisms for auditory processing of communication signals. There is strong evidence that context plays a role in the processing of acoustic signals. Yet, the mechanisms that govern this process are still not fully understood. Eptesicus fuscus bats emit a wide array of communication calls, including food claiming calls, aggressive calls and appeasement calls. We developed a novel competitive foraging task to explore the role of behavioral context in auditory responses to social calls. With this approach, we recorded neural population responses from the IC of freely interacting bats. Analysis of our neural recordings from the IC show stronger population responses to individual calls during behaviorally aggressive events. These results indicate that behavioral context plays a role in the modulation of neuronal population responses to social vocalizations in the bat IC. |
