Neural Systems Underlying Speech Categorization

Dr. Chandrasekaran's research examines the neurobiological computations that underlie speech perception and learning, using an interdisciplinary, computational, and lifespan approach. From a clinical perspective, Dr. Chandrasekaran's laboratory hopes to develop a richer understanding of the neurocognitive sources of individual differences in speech processing. This laboratory aims to develop optimized and neurobiologically-informed auditory training approaches for second language learning, learning impairments, and auditory processing deficits. Using cognitive neuroscience approaches (fMRI, DTI, cortical and subcortical EEG and computational modeling), the laboratory focuses on: 1. Understanding brain dynamics during speech perception in challenging listening environments 2. Understanding the functional dynamics of neural circuitry underlying speech categorization.
