Wang, Laboratory of Auditory Neurophysiology discoveries published in Nature
Dr. Xiaoqin Wang, Principal Investigator of the Laboratory of Auditory Neurophysiology was recently recognized in the international science journal Nature for research into interpreting responses of the auditory cortex. The auditory cortex is thought to exhibit only transient responses to sound stimulation, which sits oddly with its role in processing complex sounds such as human speech and music. New work on the auditory cortex of awake marmosets conducted in Dr. Wang's laboratory shows that the neurons can discharge in a sustained manner for a prolonged period.
It is possible to imagine how a sound picture can be built up: select neurons fire throughout the duration of the sound when it is their preferred stimulus, while the responses of other neurons fade away after the onset of to what, for them, is a non-preferred stimulus.
