Current Research Projects:

Dr. Wilson's laboratory utilizes advanced functional and structural neuroimaging to understand how electrical activity in large-scale human brain networks gives rise to normal and aberrant cognitive processes.  Specifically, the team uses magnetoencephalography (MEG) to measure the dynamics of brain function in real time, and combines high-resolution structural MRI with computational neuroanatomical techniques to quantify the thickness of cortical gray matter in healthy children and adults, as well as those with neurological and/or psychiatric disoders.  Beyond MEG and structural MRI, the team also uses functional MRI, diffusion-weighted imaging, and noninvasive brain stimulation methods to address emerging questions in basic and translational neuroscience.

Dr. Wilson's laboratory is currently funded by grants from the National Institute of Health (NIH), the National Science Foundation (NSF), the American Heart Association (AHA), and private foundations.

Current projects include:

- A longitudinal study of healthy and pathological aging in healthy adults and those with cognitive impairments subsequent to HIV-infection.  In this work, the team is studying how the brain networks serving attention and working memory change as a function of aging, and whether early signs of impairment can be discerned in the function or structure of the brain.  The team is also evaluating sex differences among these variables, and how one's molecular age is reflected in the structure and function of their brain.

- The developmental trajectory of healthy brain development in 9-14 year-old childnre.  This study evaluates how the cortex and white matter pathways maturate as children grow into adolescents, and examines how specific genetic markers impact this maturation.  A particular focus of the study is on neuronal dynamics and how connectivity in specific brain networks changes during the transition from childhood to adolescence.

- An investigation of how type 1 diabetes (T1D) affects cognitive and neural function across the life span.  The main goals of this project are to quantify the impact of glycemic dysregulation and disease duration on brain and cognitive health in patients with T1D who are otherwise healthy (i.e., free of heart disease and obesity).

- A study identifying the underlying mechanisms of an emerging type of noninvasive electrical brain stimulation.  This work currently focuses on healthy young adults and aims to determine the neurophysiological bases of enhanced and degraded cognitive function following stimulation of specific brain areas.

- A translational study of how chronic heart failure (CHF) and dyspnea (breathlessness) affects brain function and cerebral blood flow in older adults (with and without CHF).  The underlying molecular mechanisms of these alterations are then probed in rats with CHF (with Dr. Harold Schultz).

- The impact of chronic marijuana use on the aging process.  This study identifies whether heavy marijuana use accelerates cognitive and neural aging using MEG, structural/functional MRI, and neurobehavioral methods.

The Wilson laboratory is highly collaborative and involved in several ongoing studies that are based in other laboratories at UNMC, University of Nebraska-Omaha, Creighton University, Boys Town National Research Hospital, the Mind Research Network, Tulane University, and beyond.

“Neurophysiological markers of HAND and the impact of aging: Evidence from MEG”
Role: Principal Investigator
This award uses MEG, functional MRI, structural MRI, and diffusion tensor imaging (DTI) to evaluate the neural mechanisms of HIV-associated neurocognitive disorders (HAND), which affect between 35-70% of all HIV-infected patients. A longitudinal component of the study will evaluate how HIV-infection differentially modulates the decline in cognitive and neural function that is associated with normal healthy aging.

“Administrative Supplement: Sex differences in aging and the neurophysiological markers of HAND”
Role: Principal Investigator
This administrative supplement supports the recruitment of 60 additional women (30 HIV-infected and 30 healthy women), which pushes total enrollment in the parent project to approximately 250 participants. This increased sample size will enable adequately-powered statistical testing for sex differences in healthy aging, and the accelerated aging that is often associated with HIV-infection and HAND, among other conditions.

“Administrative Supplement: Linking molecular markers of aging, the epigenome, and functional neuroimaging”
Role: Principal Investigator
This administrative supplement supports epigenetic analyses, including DNA methylation, on all participants (patients and controls) who were enrolled in the parent R01 and S1 projects. We will extract molecular markers of aging and assess how these metrics coalesce with indices of brain structure and function in healthy and HIV-infected participants ranging from 22 to 76 years-old. Other epigenetic analyses will also be conducted.

Dynamics and Related Genetic Factors in Childhood”
Role: Co-Principal Investigator
This award supports a longitudinal study of structural and functional brain development in typically-developing 9-14 year-old participants, as well as a multi-institutional training program in computational and cognitive neuroscience. Genetic data, structural MRI, functional MRI, diffusion MRI, and MEG will be collected annually on about 225 youth at the University of Nebraska Medical Center (PI: Wilson) and the Mind Research Network in New Mexico (PI: Calhoun/Stephen). Multimodal imaging and genetic data will be processed using advanced network modeling approaches developed through the project, which are also a key aspect of the training mission.

“The impact of marijuana use on brain and cognitive function in HIV-infected patients”
Role: Principal Investigator
This AIDS-Science Track Award for Research Transition (A-START) will enable the PI to expand his research program into the area of drug abuse. The main project will utilize neuroimaging and neuropsychological testing to identify how HIV-associated neurocognitive disorders are affected by chronic marijuana use, and determine whether the severity of cognitive deficits is connected to the extent of marijuana consumption (heavy vs. light).

“Exploring the neurological basis of dyspnea and its impact on exercise intolerance in heart failure”
Role: Co-Principal Investigator
This translational study will identify the cortical brain circuits that underlie the sensation of dyspnea in humans with and without chronic heart failure (CHF) using MEG, and determine whether alterations in these circuits are linked to reduced exercise capacity in CHF. In parallel, dyspneic stimuli will be used to activate analogous brain circuits in rats with and without CHF, and we will test whether reversal of oxidative changes in dyspnea-related brain circuits improves autonomic and respiratory function, as well as exercise capacity in conscious CHF rats.
