This article features the organization Faculty for Undergraduate Neuroscience. FUN was established by a group of neuroscientists dedicated to innovation and excellence in undergraduate neuroscience education and research. In the years since its inception, FUN has grown into a dynamic organization making a significant impact on the quality of undergraduate neuroscience education. Through the participation of both faculty and students, FUN provides a unique support system to enhance and encourage undergraduate research experiences in neuroscience. The growth of the organization to include more than 500 members from around the world is indicative of the critical role FUN fulfills. FUN strives to serve this diverse and geographically diffuse group by relying heavily on Internet-based communications that are freely accessible to all. Whether through the organizational Web page, the listserve, or the eJournal "JUNE," FUN has been able to reach out to faculty involved in undergraduate education across the country and around the world. The result is a membership with a passion for improving undergraduate curricula and a broad range of ideas and expertise to bring to this effort. (Contains 1 figure.)
