However, many cell-to-cell signaling molecules remain poorly characterized and for those that are known, their localization and dynamics are oftentimes unknown. A suite of small-scale measurement approaches are described that allow the investigation of individual neurons and small brain regions; these approaches include capillary scale separations, direct mass spectrometric-based profiling and mass spectrometry imaging.\r\n\r\nSeveral applications of single cell microanalysis are highlighted including the discovery of unusual metabolites to characterizing the neuropeptides in single cells. Single cell assays allow differences in the metabolome and peptidome from supposedly homogeneous populations of cells to be explored Imaging mass spectrometry and dynamic sampling of the extracellular environment also provide a functional context for the discovery of novel cell to cell signaling molecules. \r\n\r\nOur overarching goal is to uncover the complex chemical mosaic of the brain and pinpoint key cellular players in a range of physiological and pathological processes.\r\n","summary":null,"format":"plain_text"}],"field_subtitle":"","field_summary":[{"value":"The Vasser Woolley Distinguished Lecture is sponsored by the Analytical Division of the School of Chemistry and Biochemistry","format":"plain_text"}],"field_summary_sentence":[{"value":"Vasser Woolley Distinguished Lecture"}],"uid":"34592","created_gmt":"2017-10-23 19:58:42","changed_gmt":"2017-10-23 19:58:42","author":"wh105","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-10-26T16:30:00-04:00","event_time_end":"2017-10-26T18:00:00-04:00","event_time_end_last":"2017-10-26T18:00:00-04:00","gmt_time_start":"2017-10-26 20:30:00","gmt_time_end":"2017-10-26 22:00:00","gmt_time_end_last":"2017-10-26 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":["free_food"],"related_links":[{"url":"http:\/\/www.chemistry.illinois.edu\/faculty\/jonathan_sweedler.html","title":"Research interests focus on developing new approaches for assaying small volume samples, and in applying these methods to study "}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"176016","name":"novel interactions"},{"id":"176017","name":"capillary separations"},{"id":"5819","name":"analytical chemistry"},{"id":"166928","name":"School of Chemistry and Biochemistry"},{"id":"4896","name":"College of Sciences"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"Prof. Ronghu Wu - ronghu.wu@chemistry.gatech.edu\r\n","format":"plain_text"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
