Research Specialty
Anatomy and physiology of auditory cortex

Research Description
Dr. Hackett studies the organization of the auditory cortex combining anatomical and neurophysiological techniques. The major emphasis of the research is to assemble a model of auditory cortical processing from: 1) identification of the cortical areas involved in the processing of auditory information; 2) reconstruction of the circuitry that underlies the auditory cortical network; 3) recording of neurophysiological response profiles for neurons in individual areas; and 4) comparative analyses of these features between species. The long term goal of this research is to establish a comprehensive model of auditory processing in the human cerebral cortex. Research is supported by the National Institutes of Health (NIDCD).
