I am a member of Dr. Burdo's Fall 2011 Introduction to Neuroscience class at Boston College and part of the curriculum this semester is a project in which groups of students add to and improve existing Wikipedia page stubs on topics relating to Neuroscience. This project is part of a larger initiative by the Society for Neuroscience to improve the quality of incomplete articles on Neuroscience.
