Subject: NIH Neuroscience Seminar Series: September 28, 2009

 

You are invited to attend the NIH Neuroscience Series lecture on September
28, 2009 at noon in the Lipsett Amphitheater of the NIH Clinical Center, 10
Center Drive, Bethesda, MD.  This lecture is the 2009 Cantoni Memorial
Lecture.

 

XIAOQIN WANG, PH.D., Biomedical Engineering Department, Johns Hopkins
University, will present the seminar on "Neural mechanisms for
auditory-vocal interaction in the marmoset brain".   

 

Dr. Xiaoqin Wang's research focuses on the understanding of the structure
and functions of the primate auditory cortex and the neural basis of vocal
communication. He has developed a unique non-human primate
neurophysiological and behavioral model to study these questions, using a
highly vocal New World monkey, the common marmoset (callithrix jacchus).
Using this model system, his laboratory has systematically studied neural
coding properties of the auditory cortex in awake and behaving conditions
and revealed specialized cortical representations of complex sound features
such as pitch. His laboratory has also discovered neural mechanisms involved
in vocal feedback control and self-monitoring during speaking. These results
demonstrate that neural representations of complex acoustic environment in
the auditory cortex result from transformations of acoustic signals to
perceptual dimensions and such representations are modulated by motor(vocal)
system during natural vocal behaviors. Using newly developed wireless neural
recording techniques, his laboratory is currently studying neural processing
in the brain when a subject engages in vocal communication with
conspecifics.

 

Dr. Xiaoqin Wang received B.S. degree in electrical engineering from Sichuan
University (China) and M.S.E. degree in electrical engineering and computer
science from University of Michigan. He began his study of the auditory
system while pursuing his Ph.D. degree in biomedical engineering at The
Johns Hopkins University. He did his postdoctoral research on somatosensory
and auditory cortical neurophysiology at University of California, San
Francisco in the laboratory of Michael Merzenich. He joined the faculty of
Biomedical Engineering Department at The Johns Hopkins University School of
Medicine in 1995 and is currently Professor of Biomedical Engineering,
Neuroscience and Otolaryngology. Dr. Wang is also the director of Tsinghua
University (China) and Johns Hopkins University Joint Center for Biomedical
Engineering Research.
