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. Current work in the Laboratory focuses on the application of neurophysiological imaging methods for understanding disease pathophysiology and for quantifying the neuronal changes that accompany select pharmacotherapies directed at these diseases.
The primary neurophysiological focus is on high-frequency cortical oscillations due to their known role in information processing and network level inter-regional communication. At present, major effort is directed toward using these methods to further understand the pathophysiology of attention-deficit/hyperactivity disorder (ADHD) and the primary mechanisms that underlie stimulant-mediated symptom suppression. Amphetamines are widely recognized as an effective treatment option for patients with ADHD, and by understanding their mechanism of action one can extract key insights on the basic pathophysiology.
Another line of work in Dr. Wilson’s Laboratory evaluates the impact that dopaminergic treatments have on cortical function and cortical-subcortical oscillatory activity in patients with mild to moderate Parkinson’s disease. Currently, it is widely recognized that Parkinson’s is associated with pathological levels of cortical-subcortical synchronization, and work in Dr. Wilson’s Laboratory focuses on how such neuronal synchronization is affected by dopamine-based treatments and disease progression.
Finally, Dr. Wilson’s Laboratory investigates candidate biomarkers for HIV-associated neurocognitive disorders (HAND). Between 35-70% of HIV-infected patients will develop cognitive impairments and the pathophysiology is not well understood. Currently, diagnoses are made by exclusion of other potential causes, as there are no diagnostic tests or specific biomarkers that can precisely pinpoint HAND. Thus, the goal of this work is to develop objective biomarkers of HAND that can be used for diagnoses, monitoring disease progression, and for testing new candidate treatments.
