Overview
The Arnsten Lab studies molecular influences on the higher cognitive functions of the prefrontal cortex (PFC), with the overarching goal of developing rational treatments for cognitive disorders and mental illness. The lab uses a multi-disciplinary approach to understand mechanisms influencing working memory at the cellular and behavioral levels. Research has focused on how the arousal pathways rapidly alter PFC network strength through intracellular signaling mechanisms, a process termed Dynamic Network Connectivity. Our data explain how exposure to stress and/or inflammation causes the rapid loss of PFC cognitive abilities, and how genetic mutations in molecules that regulate these pathways can lead to symptoms of mental illness. Dysregulation of these pathways with advancing age leads to loss of neuronal firing, cognitive impairments,and increased vulnerability for degeneration including tau pathology in Alzheimer's disease. Understanding these mechanisms has led to successful new treatments for patients with PFC dysfunction, including medications for Attention Deficit Hyperactivity Disorder, Post-Traumatic Stress Disorder, long-COVID and delirium.
