Dr. Ramachandran is interested in how sounds are encoded in the brain by the activity of populations of neurons, and how these populations of neurons may subserve auditory perception and behavior. To that end, he uses an approach that combines behavior, electrophysiology, and quantitative analysis and computational modeling. Current projects include an investigation into the neuronal basis of detection of sounds (tones, amplitude modulated tones, human communication sounds, etc.) in noisy, naturalistic environments. The long term goal of the research done in the lab is to investigate dysfunction in encoding sounds and the dysfunction in the linkages between neuronal activity and perception in older or hearing impaired subjects, and come up with improved devices/signal processing for recovery of function. Research in the lab is supported by the National Institutes of Health (NIDCD).
