Detailed Biography:

Dr. Tracy Xie is a professor at the Department of Psychiatry and Biobehavioral Sciences. She earned her doctorate degree in medicine and physiology at Peking University, China. She received postdoctoral training in electrophysiology and molecular biology at National Institute of Health (NIH) and Duke University in North Carolina, where she studied regulation of hippocampal synaptic plasticity by endogenous neuropeptides. Since joining UCLA faculty in 1995, Dr. Xie has been studying cellular mechanisms of neural and synaptic plasticity, and implications of such mechanisms in drug dependence and memory loss related to aging and Alzheimer's disease. Her research is funded by grants from National Institute of Aging (NIA), National Institute on Drug abuse (NIDA), and Alzheimer's Association.

MeSH Terms:

What is MeSH?

Medical Subject Headings

We have integrated Faculty Profiles with the U.S. National Library of Medicine's MeSH terms. For every publication added to a profile, we pull its MeSH terms and display it here. This enhancement allows you to search for research themes of our faculty members.

Click on any of the terms below to see additional researchers with similar keywords.

MeSH is:

  • an acronym for Medical Subject Headings.
  • the U.S. National Library of Medicine's controlled vocabulary (thesaurus).
  • a vocabulary that gives uniformity and consistency to the indexing and cataloging of biomedical literature.
  • a distinctive feature of MEDLINE.
  • arranged in a hierarchical manner called the MeSH Tree Structures.
  • updated annually.

MeSH Vocabulary includes four types of terms:

  • Headings
  • Subheadings
  • Supplementary Concept Records
  • Publication Characteristics (or Types)

Over 26,000 MeSH headings (also called "main headings" or "descriptors" represents concepts found in the biomedical literature

Subheadings - (also called qualifiers) are attached to MeSH headings to describe a specific aspect of a concept.

Supplementary Concept Records are over 200,000 terms in a separate thesaurus from the Medical Subject Headings. These are primarily substance terms, but also include some protocols and rare desease terms. These terms are updated weekly.

Publication Characteristics or (Publication Types) describe the type of publication being indexed; i.e., what the item is, not what the article is about.
