     Dr. Chen obtained his B.S. degree in the Department of Biology at Inner Mongolia University, 1997-2002. During 2002-2008, Dr. Chen did vision researches for his PhD in the lab of Dr. Muming-Poo (Fellow of the American Academy of Sciences) and Dr. Yang Dan (University of California at Berkeley) at the Institute of Neuroscience, Chinese Academy of Sciences, Shanghai. Then, Dr. Chen continued to work as an assistant investigator in the lab in 2008-2009. After that, Dr. Chen did motion perception researches as a postdoc with Dr. Dora E. Angelaki (Fellow of the American Academy of Sciences) and Dr. Gregory C. DeAngelis at Washington University in St. Louis, School of Medicine, U.S.A in 2009-2012, and at the Baylor College of Medicine in Houston, U.S.A in 2012-2014. Dr. Chen joined the Institute of Neurology and Cognitive Sciences, Qiushi Academy for Advanced Studies, Zhejiang University, in February 2014 as a Professor and Head of the Laboratory of Perception and Cognition. His main interests are the neural mechanisms underlying spatial perception, object recognition.

Research Interests

    The activity of human brain solves two basic questions: "Where" and "what." Brain research shows that parietal and temporal cortices play important roles in the function of object recognition and spatial encoding respectively. Our group will combine the research method of electrophysiological recordings, functional magnetic resonance imaging (fMRI), and optical genetic etc. to study the neural mechanism of these functions by recording and analyzing response characteristics of these cortical neurons. Our researches include the following directions:

The spatial encoding of sensory input signals in the brain

   In order to control our own movement and interact with the environment, the brain needs to be updated in real time the status information of all body parts and surrounding environment in space. The information was perceived by various receptors of the body, then transferred into the brain and integrated there to be involved in the development of the sport and the movement controlling of body parts. The parietal cortex is thought to play a key role in this process. The cortical neurons in this area receive input signals from multiple sensory systems (including visual, vestibular, auditory, and somatosensory). In different regions of the parietal cortex, these signals are encoded in different spatial coordinate systems. We will systematically study the spatial encoding of sensory signals in these brain regions, and then in further to explore these sensory signals coded in different coordinate systems are integrated through what kind of mechanisms.

Neural mechanisms of object recognition

   Neurons in the temporal cortex receive input signals primarily from visual and auditory systems and play important roles in the advanced functions of pattern recognition, object recognition, memory, and languages. In particular, recent studies suggested that neurons in certain areas of the temporal cortex show very specific responses to facial stimuli. Fatherly, we will use newly designed facial stimuli to explore the neural mechanisms of the face recognition.

Development of auxiliary research tools

  We will develop corresponding hardware and software tools based on the requirements of our research to assist our experiments.
