Research Interest: Neuroplasticity and Brain Diseases Emotion and motivation are two basic, interlinked concepts in neuroscience, with ramifying connotations across psychology and philosophy. Thus far, neuroscience cannot yet provide coherent explanations for why some stimuli cheer us up whereas others make us sad, why my fishing trip to a picturesque river is given up in favor of typing this paragraph, and why reading and memorizing knowledge that used to be so boring for me as a kid become so rewarding after a 20-year of “habituation”.
Our long-term research goal is to understand the neural mechanisms underlying emotional and motivational responses. We focus on animal models related to drug addiction. Addictive drugs are among the most effective and efficient external stimuli that evoke the strongest emotional and motivational states. Once “hijacked” into the addictive state, an individual will be primarily motivated by an exceedingly strong emotional state, the drug-seeking/craving state.
We hypothesize that strong incentive stimuli, such as experience of drugs of abuse, shift the emotional and motivational states by rewiring the neural circuits in the brain reward pathway through the creation of new and elimination of old neural connections. To test this hypothesis, we have been examining several novel forms of neural plasticity upon exposure to cocaine.
These lines of research in the laboratory are currently carried out by several highly motivated young souls, who are equipped with a combination of molecular, cellular, electrophysiological, imaging, and behavioral expertise. In addition, our studies are conducted in close collaboration with the labs of Oliver Schlüter, Yanhua Huang, and Eric Nestler.
