My three main areas of interest are 1) exploring cognition with fMRI 2) brain development in children and 3) familial transmission of affective disorders. My thesis research which began in Dr. Clint Kilts' lab allowed me to combine these three areas in a unique collaboration with the Women's Mental Health Program at Emory (WMHP) and the Child and Adolescent Mood Program at Emory (CAMP). Generally, I am interested in social cognition, reward processing, and executive functioning in the brain and how these processes change as the brain matures. I am also interested in the functional and anatomical brain changes that occur with the onset of depression and anxiety disorders and the effects of prenatal exposure to depression, stress, and antidepressants on brain development.

Humans are most closely related to chimpanzees and bonobos, yet little comparative neuroanatomical and connectivity data are available. My research concerns the anatomical structure and connectivity of the superior temporal gyrus and superior temporal sulcus in humans, chimpanzees, and macaques, using diffusion tensor imaging and immunohistochemical techniques. These regions play critical roles in audiovisual integration, including language and biological motion processing. I am interested in identifying similarities and differences between humans and chimpanzees, and further, postulating how these changes in neural substrate may be responsible for behavioral and cognitive differences in these species.

James Burkett james.p.burkett@gmail.com

My overarching interest is in the neurobiology of positive emotions. More specifically, I am investigating empathy-based behaviors with the goal of probing different dimensions of social cognition. Consolation is one such behavior that is ideal for investigating the type of social cognition that is deficient in autism - specifically, the ability to look at another individual, understand their emotional state, and form an appropriate response. Consolation occurs naturally in a small number of animal species, but to date no experimental models have emerged that would permit the study of the neurobiology of this behavior. I hope to demonstrate that prairie voles are capable of consolation, that they can be used to investigate the neural correlates of consolation, and that an assay of consolation can be used to elaborate on social cognitive mechanisms relevant to autism.

My research interests include functional neuroanatomy, synaptic plasticity and neuromodulation, and nervous system development.

To this end, I use in vitro electrophysiology and molecular approaches to study activity- and experience-dependent changes in affective circuitry.

My research is focused on determining the effects of infant maltreatment (a form of early life stress) on neurodevelopment and how these alterations are related to psychopathology. We use in vivo imaging techniques to follow structural changes in the brains of rhesus macaques with histories of maternal physical abuse and neglect from birth through adulthood. We combine our measures of brain development with behavioral observations to relate structural changes we find to alterations in social behavior. The ultimate goal is to use this information to development effective preventative therapies and treatments in human victims of maltreatment.

My main research interests are in understanding the molecular mechanisms and pharmacotheraphy of age-related cognitive decline as well as neurodegenerative diseases, specifically, Alzheimer's Disease (AD). In order to do this, I have been heavily involved in drug development and recently developed the first truly subtype-selective M1 muscarinic acetylcholine receptor agonists. Since deletion of M1 function leads to hippocampal memory impairments and exacerbates amyloid AD pathology, these compounds will serve as vital research tools to probe the involvement of cholinergic circuitry in the context of aging and AD at a resolution never before possible. In order to do this my work at Emory focuses on 1) in vivo electrophysiology to record hippocampal neuronal activity of place cells in awake and behaving, aged rats as well as 2) chronic dosing of transgenic AD mice in a prophylactic treatment trial focused on preventing AD onset.

Yvonne Ogbonmwan yogbonm@emory.edu

I am studying how chronic voluntary exercise reduces the incidence of relapse in individuals with a history of substance abuse. However, the mechanism for this phenomenon remains unknown. Chronic voluntary exercise selectively upregulates galanin mRNA (a neuropeptide that inhibits norepinephrine release) in the locus coeruleus. Norepinephrine is a neurotransmitter that is critically involved in mediating the cocaine-primed reinstatement ( an animal model of relapse). Thus, I propose to determine the role of exercise-induced galanin upregulation on cocaine-primed reinstatement and NE release. My research uses intravenous self-administration to analyze rat behavioral responses to cocaine, in situ hybridization and real-time PCR to assess protein galanin mRNA concentrations, and michrodialysis to measure extracellular NE concentrations.

I am interested in translational neuroscience, particularly the process of designing and conducting studies that can be efficiently moved from the lab to the clinic. I am currently working in primary dorsal root ganglion (DRG) cell culture to determine which adeno-associated virus (AAV) serotypes that best transduce nociceptors, as well as investigating methods to optimize viral delivery to sensory neurons. I am also working with HSV-based viral vectors to selectively deliver transgenes to the soma of primary sensory neurons, which results in disrupted synaptic transmission between nociceptors and primary afferents. Gene-based neuromodulation at this synapse has been effectively applied to various types of pain transmitted via the spinal cord dorsal horn. I plan to apply these vectors in rodent models of craniofacial pain, targeting sensory neurons in the trigeminal ganglia instead of the spinal cord DRG.

I am interested in the proximate neural mechanisms by which individuals living in complex social groups encode and subsequently recognize social signals emitted by their conspecific group members. Specifically, I plan to measure the activity of single neurons and the local field potential in the monkey hippocampus and amygdala simultaneously in response to images of faces and non-social stimuli while recording the point of gaze using infrared eye tracking. This affords the opportunity to study social cognition and memory in an ethologically relevant context, as well as test the effects of exogenous oxytocin on these processes. This research may have implications for people with autism, who are impaired in these faculties and show improvement following administration of intranasal oxytocin.
