Deciphering and manipulating the cellular signaling circuits for feeding behaviors using approaches including electrophysiology, pharmacogenetics and optogenetics.
At the newly established Molecular Cellular Neuropsychiatry Laboratory at Upstate, directed by Dr. Yao, the mission is to find out how psychiatric diseases damage brain cells and their proper wiring, and how these impairments cause mental illnesses. Our hypothesis is that impaired assembly, function, and plasticity of synapses (small junctions that permit nerve cells to pass an electrical or chemical signal from one to another) and neural circuits underlie cognitive, memory, and emotional deficits of essentially all neuropsychiatric diseases. We are investigating this hypothesis using a number of state-of-the-art molecular, cellular, and electrophysiological technologies on genetically engineered mouse models and induced pluripotent stem cells (iPS cells) derived from human patients. Our major interests are addiction, schizophrenia, autism, and primarily prefrontal cortex related brain and mental diseases. Our previous work done at Harvard Medical School has identified new brain signaling pathways that regulate synapse formation and stabilization and neural circuit rewiring that provide fundamental breakthroughs about the pathogenesis of these diseases. At SUNY Upstate we will continue our cutting-edge research, and the knowledge obtained will be an prerequisite for development of more effective treatment strategies for these diseases.
