Auditory neuroscience, sensory systems, neuroanatomy, and attention.
Our brains are constantly presented with the problem of extracting meaningful information from the surroundings, and in fact, our optimal behavior and survival depend on this function of the brain. My research focuses on understanding the anatomy and physiology of higher centers in the brain, such as the cerebral cortex, which help animals extract sound information from the environment. To illustrate how complex this task can be, imagine being at a loud party where multiple people are talking and music is playing. Yet, most people are able to focus on one conversation even when many conversations are taking place at the same time. I am trying to understand the organization and functions of the neurons that help us accomplish similar tasks. Even more specifically, my research focuses on describing structural and functional heterogeneity between groups of corticofugal neurons that project to the inferior colliculus - a midbrain integration center for sound information. Our research findings are suggestive of the existence of at least two classes of corticocollicular neurons, one of which is most likely involved in fast modulation of responses to sound, while the second class may provide more long-lasting influences on sound processing that arise from memory and emotion systems in the brain.
