Primary sources in the Neurosciences will vary depending on the course and research assignment given.

Empirical Research
According to the APA Dictionary of Psychology to be 'empirical' research is "1. derived from or denoting experimentation or systematic observations as the basis for conclusion or determination, as opposed to speculative, theoretical, or exclusively reason-based approaches. 2. based on experience."

Peer Review
Refers to the process that a scholarly book or journal article goes through when an authors research and writing is evaluated by experts in their discipline or field.  In the case of a journal article, peers review articles to determine if they'll be accepted and published in a specific journal.  In the case of psychology journals expert peers are evaluating and checking the accuracy and originality of the research being reported on.

Primary sources are original, uninterpreted information.  Scholars analyze primary sources in order to answer research questions. Examples of primary sources vary by discipline.

Examples in the humanities:

• a novel
• a painting
• a theatre performance

Examples in the social sciences:

• a political, social, or economic theory
• a dataset
• the results of an experiment published in a peer-reviewed journal

Example in the sciences:

• the results of an experiment published in a peer-reviewed journal

Are original materials based on first-hand accounts of research conducted by the author(s). They are usually written at the time the research is occurring or shortly after the research is complete, and they present new information or discoveries.

Primary sources in neuroscience:

• are written accounts of original research, study, or experimentation conducted by the author(s) of the resource.
• are written accounts of primary research and are typically published in scholarly, peer-reviewed, journals, and are often published by professional associations or academic institutions.
• are often research articles and generally contain standard components, and follow a specific format or pattern.
  • typically they include an abstract, a methods section, discussion, a conclusion and a bibliography.
• can be found by looking for clues.
  • read the abstract of an article and look for statements like:
    • The research we conducted shows . . .
    • The aim of our study was . . .
    • We looked at two groups of children . . .
    • Our research concluded that . . .

When looking at a record in PsycINFO to try to determine if the resource you're looking at is a primary source, it's important to check to see if the article is an empirical study.  Look for the "methodology" field of the record.

If there is an indication that the resource you're looking at is an Empirical Study then you know that it's research-based, and is a primary source.
