Research Summary

Yi Long  Cui(Ph.D.)

We aim to establish a PET imaging- based quantitative evaluation platform for pharmacokinetics in order to elucidate the molecular dynamics associated with the ADME (Absorption, Distribution, Metabolism, and Excretion) processes in living body, and aim to develop novel disease-specific PET imaging methods to evaluate drug efficacy, during the drug developmental process. We will also focus on the development of an integrated research system combining functional neuroimaging method and classic research techniques, including electrophysiology, behavioral pharmacology, histology and genetic engineering approaches, and thereby carry out a comprehensive investigation of the molecular/cellular mechanisms underlying the psychiatric processes, especially regarding pain sensation and fatigue sensation.
