Wang Jin-Hui has received PhD from Shanghai Institute of Physiology, Chinese Academy of Sciences. After postdoctoral training in State University of New York and University of Texas, Wang has joined to University of Kansas as tenure-track assistant professor. Subsequently, Wang is appointed by Chinese Academy of Sciences as a distinguished professor. After being an independent researcher, Wang has found working principles of neurons and synapses about the conversion of inactive into active synapses, the conversion of irregular to regular transmission pattern at unitary synapse, homeostatic plasticity among subcellular compartments, spike amplification at axons as well as the functional compatibility between axonal branches and their postsynaptic partners. In terms of cellular architecture for learning and memory, Wang's group has discovered and identified associative memory cells as basic units in memory trace.
