The Sisneros Lab investigates the adaptive plasticity of the vertebrate auditory system, with a central focus on how neural and sensory mechanisms encode socially relevant acoustic signals. Our work seeks to understand how auditory systems remain flexible across the lifespan and in response to changing internal and external conditions, enabling animals to communicate effectively in dynamic environments.

​​

We use fishes as model systems to study ontogenetic and reproductive-state dependent changes in auditory structure and function, examining how auditory sensitivity, frequency tuning, and neural coding of communication signals develop across life stages and are modulated by adult hormonal state in social and reproductive contexts.

 

In addition, the Sisneros Lab studies sound source localization, examining how fishes detect and localize underwater sounds by extracting spatial information from acoustic fields in both simple and complex environments.
