Research Interests

"What's the neural code, what mechanism does it rely on and how does it participate in behavioral fitness" The nervous system can be divided in three levels: sensory areas (the input side), motor areas (the output side) and higher functions (such as decision making). A central theme in neuroscience is to relate the sensory input to the behavioral output. An important task in this endeavor is to understand how sensory signal are first encoded by the nervous system. Relevant signals must be be encoded efficiently and the information carried to higher brain areas in a format most appropriate for further processing. Our main interest is to understand how nervous systems perform this task, in other words how sensory signals are transformed by the nervous system to ultimately produce the appropriate behavior. We use a combination of in vivo electrophysiology, computational neuroscience tools, behavioral assays, histology, imaging and pharmacological manipulations. The research in our lab is at the intersection of three connected areas of neuroscience: Systems Neuroscience, Computational Neuroscience and Neuroethology.
