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 through identification and characterization of the cortical areas involved in the processing of auditory information. These goals are accomplished by a combination of methods, including: 1) anatomical tracing to identify the neuronal circuits that comprise the auditory cortical and subcortical network; 2) neurochemical and genetic profiling of those circuits; 3) neurophysiological recording of neurons; and 5) comparative analyses of these features between model 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).
