Transformation of Stimulus Representation along the Cortical Auditory Pathways

Brisbane Convention & Exhibition Centre 

Auditory cortex on the superior temporal plane and lateral convexity are key areas in the initial stages of cortical processing of sounds. More complex perceptual representations are envisioned to occur in auditory-related cortex along the ventral and dorsal processing streams, extending into prefrontal cortex and ultimately leading to behavior. To characterize the flow of information across these stages of the auditory hierarchy that ultimately leads to sensory-driven behavioral events, we examined neural activity using intracranial electroencephalography (iEEG) during semantic categorization tasks.
