About Paper:

The brain is made up of several distinct regions, each responsible for interpreting different aspects of the world around us. Among these, the auditory cortex plays a key role in processing sound. While the primary 306 UNIVERSITY OF OREGON • 2025 UNDERGRADUATE RESEARCH SYMPOSIUM TABLE OF CONTENTS auditory cortex is known to interpret basic sound features, the functional roles of its secondary subregions, particularly the dorsal and ventral areas, remain less clear. These subregions are thought to handle more complex sounds, but their specific functional roles are less well understood. In this study, we utilized machine learning techniques on neuronal populations to investigate how subregions of the auditory cortex encode sound. We found that neuronal activity patterns were more consistent within individual subregions than between different ones, indicating that each area contributes uniquely to auditory processing. Our analysis also showed that subregions responded preferentially to different sound frequencies and types, suggesting functional specialization across the auditory cortex. These insights advance our understanding of sensory encoding and speech perception, with potential applications in brain-computer interfaces and hearing technologies.
