Christian Carr and Scott Steffensen, Department of Psychology Introduction Dopamine is an important brain neurotransmitter regarding brain disorders such as substance abuse, Schizophrenia, Parkinson’s disease, attention deficit hyperactivity disorder (ADHD), and Restless Leg Syndrome (RLS). Dopamine neurons in the ventral tegmental area (VTA) and substantia nigra (SN) are inhibited by DA via DA D2 autoreceptor […]

Mnemonic Mechanisms for the Mundane: A Longitudinal Approach
Athena Howell and Brock Kirwan, Department of Neuroscience/Psychology Introduction My project focused on the neural activity associated with memory consolidation, particularly the role of pattern separation and pattern completion over an extended period of time. Pattern separation occurs when the brain successfully encodes similar experiences into distinct memories (Deng et al. 2003); for instance, pattern […]
Elucidation of Mechanisms Whereby Embryonic Chicken Limbs Develop
Broadbent, James Elucidation of Mechanisms Whereby Embryonic Chicken Limbs Develop Faculty Mentor: Jeffrey Barrow, Department of Physiology and Developmental Biology Introduction As established by John Saunders 60 years ago, the AER is required for limb growth and patterning. However, the mechanisms whereby the AER regulates these processes remain poorly understood. My professor and I propose […]
Analysis of the kinetics and recombinatorial mechanisms of HIV-1 evolution in vivo in humanized mice
Bradford Berges, MEG 2013 Final Report (submitted Oct 2015) Evaluation of how well the academic objectives of the proposal were met Several of my students have moved on to future positions, as follows: Medical school: Sterling Adams, German Cuadra, Art Lee (still interviewing), and Tyler White (still interviewing) Graduate school: Steve Hallam See below in […]
Neural mechanisms: Nicotine and Alcohol Co-dependence
Jordan Spencer and Dr. Scott C. Steffensen PhD, Department of Psychology and Center for Neuroscience Introduction: Alcohol abuse is prevalent in today’s society, causing an economic burden to the US of several hundred billions of dollars annually in direct costs alone. Several reports have estimated that 80% of those with a dependence on alcohol are […]
Neural Mechanisms of Inhibitory Control: Predictors of Eating Behavior in Obesity
Kaylie Carbine ande Michael Larson, Department of Psychology and Neuroscience Introduction Obesity is a prominent public health concern associated with increased risk of high blood pressure, chronic diseases, and mortality (National Institutes of Health, 2011). Understanding the neural underpinnings of obesity may prove beneficial for effective weight control interventions. Specifically, decreased ability to inhibit responses […]
Autophagy-Mediated Mechanisms of Chemoresistance in Cancer
David Broadbent, Dr. Joshua Andersen, Department of Chemistry and Biochemistry The resistance of tumor cells to chemotherapy is a critical problem in the clinic and is a common cause of mortality in cancer. Emerging data suggests that resistance to chemotherapy is caused by a tumor-expressed protein called 14-3-3ζ, yet the mechanism to explain 14-3-3ζ-mediated chemoresistance […]
Mechanisms in Learning and Memory
Michael McNeil and Dr. Jeffrey Edwards Physiology and Developmental Biology Endocannabinoids are molecules that play an important role in neuromodulation and are also known to be a factor in many peripheral nervous system functions such as appetite and pain sensation. Recent discoveries have also shown that endocannabinoids and their cell-signaling mechanisms are found within the […]
Mechanisms and Consequences of Conifer Expansion in Aspen Forests
Sam St. Clair, Plant and Wildlife Sciences We fully met the objectives of the study and have published numerous papers from the proposed work. The mentoring environment was highly successful based on the high number of student co-authors and the more than 15 undergraduate students mentored during that two year period. Mentored undergraduate research participants: […]
Mechanisms of the Role of Religion in Adolescence: A Case Study of Palestinian Youth
Lance Erickson and Dr. Brian K. Barber, Sociology The role of religion in adolescence has been given considerable attention in past decades. The majority of this attention has been concerned with religion as a social control mechanism (1), and therefore has focused on its relationship to adolescent deviance and drug use. Although relatively few in […]
