Welcome to the UNC Biobehavioral Lab!

Become Familiar With Biomarkers, Biobehavioral Equipment & Clinical Significance

The Biobehavioral Laboratory (BBL) was initiated in 1989 as part of the Research Support Center (RSC) and the UNC School of Nursing. The term biobehavioral refers to the interface of biological and psychosocial factors that underlie individual responses to acute and chronic illness. Since inception, the BBL has expanded in its mission to enhance knowledge and skills in biobehavioral science, physiological measurement and instrumentation.

The laboratory houses a number of instruments for the monitoring of physiologic parameters such as electrical brain activity, cardiac output, oxygenation, body composition and heart rate responses. The laboratory facility supports on-site sleep research and other measurements of interest to faculty and students. The BBL also has been expanded to include a nutritional research and behavioral observation suite. This suite houses an observational room equipped with 6 in-wall cameras and a monitoring room with video recording and editing software.

The BBL staff is committed to assisting and promoting faculty and graduate students' efforts in the use of biobehavioral measures and physiological parameters in their research. The BBL is located on the ground floor of Carrington Hall, Rooms 10 and 03. Faculty and graduate students are encouraged to visit. For more information on how to request equipment or a research consultation with BBL faculty, feel free to call 966-7598 or email us at sonbbl@unc.edu.

Salivary Bioscience Training

The Biobehavioral Laboratory in the School of Nursing is certified by Salimetrics, LLC as a “Center of Excellence" for salivary hormone analysis. We offer a two day workshop to evaluate human Salivary Cortisol and Alpha-Amylase. Participants on the 2nd day will be trained to use Enzyme-Linked Immunosorbent Assays (ELISA or EIA).
