Neurons communicate through the release of chemical messengers (e.g., neurotransmitters, neurohormones, and neuropeptides), which are packaged intracellularly in submicrometer sized structures called secretory vesicles. During exocytosis, the fundamental method for neurotransmission, vesicles migrate to the plasma membrane of a cell, fuse, and release their contents into the extracellular space. These messengers can then bind to receptors on a target cell, thus inducing a cascade of signaling events in a complex network. The overall goal of my research is to elucidate molecular events on a subcellular level during cell communication with electrochemical method and secondary-ion mass spectrometry to understand mechanism of learning and memory, drug abuse effects, as well as neurodegenerative diseases like Parkinson´s disease.
