Behavioral Neuroscience Laboratory (BNL)

Faculty Director

About Us

logo The Behavioral Neuroscience Laboratory is located in Williams Hall. The graduate student component of the lab is under the direction of David W. Harrison, Ph.D. He is a faculty member in the Clinical Science Program, former staff neuropsychologist for the New Orleans Saints football team, and director of neuropsychological services at HCA Columbia Lewis Gale Medical Center in Roanoke/Salem.  The undergraduate component of the lab is under the direction of Patti K. Harrison, Ph.D., who is a faculty member of the Biopsychology Program.

A functional cerebral systems approach is used to establish brain-behavior relationships. Research in the lab uses a variety of neuropsychological and psychophysiological methods, including structural MRI, quantitative electroencephalography (QEEG), electro-oculography (EOG), electromyography (EMG), cardiovascular, glucose, blood assays, behavioral measures, and others. At HCA Columbia Medical Center in Roanoke students are trained in neuropsychological assessment and therapies based on an integration of structural MRI evaluation, standardized  neuropsychological testing, psychophysiological assessment, and syndrome analysis techniques.

Current Research Projects

The lab uses a functional cerebral systems approach to study the neuropsychology of emotion, hostility, and cardiovascular regulation. Behavioral and psychophysiological indices are measured across systems. Task performance and psychophysiological fucntioning are examined as a function of hostility level to discover brain-behavior relationships. Additionally, research examines sex differences, dual-task performance, the effects of aging, and cardiovascular functioning in relation to stress and negative emotion.

Current Projects

  • Hemispheric laterality and sex differences
  • The neurophysiological correlates of CBT and ACT
  • Frontal eyefield functioning in hostility, anxiety, and depression.
  • Affective verbal learning in high and low hostile women.
  • EEG correlates of neuropsychological tests.
  • The neurophysiological correlates of boredom.

If you are an undergraduate student at Virginia Tech and interested in participating in research you can sign up on the Psychology Department's Experiment Management System.

Recently Completed Projects

  • An investigation of premotor frontal eye field regulation of rapid eye movements in high and low hostile participants.
  • Quantitative electroencephalogram responses and reaction-induced increases in cardiovascular reactivity in low and high hostility levels.
  • Emotion and arousal: A dynamic evaluation of relative activation states.

Joseph Carmona is a specialist in clinical neuropsychology currently working at Walter Reed Medical Center, while completing his internship experience.

Rosemary Huntzinger, Ph.D.

Dr. Huntzinger was an assistant professor at Brown University and Bradley Hospital.  Her specialization is in child clinical neuropsychology.

D. Erik Everhart, Ph.D.

Dr. Everhart is associate professor at Eastern Carolina University, where he has been very productive in research and clinical efforts in neuropsychology and neuroscience.

Heath Demaree, Ph.D.

Dr. Demaree is now an Associate Professor at Case Western Reserve where he has contributed broadly to neuroscience literature on emotion theory through his extensive publications and grant activities.

Paul Foster, Ph.D.

Dr. Foster received his Ph.D. in Clinical Psychology in May 2004. While in the lab, he researched the EEG correlates of emotional memories, arousal, cardiovascular regulation, and neuropsychological tests. Dr. Foster also designed several neuropsychological tests, including the Figure Arrangement Test. He completed his Clinical Internship at the University of North Carolina, Chapel Hill. Dr. Foster was previously at the University of Florida in the Behavioral Neurology Department but has moved back to his family's land and academics at Middle Tennessee State University.
