Neuroscientists at Pennsylvania State University are studying the brains of mice to understand the neural mechanisms of nightmares and their links to anxiety-related mental health disorders. The research aims to identify how nightmares affect brain function and could lead to new treatments for conditions like PTSD and Alzheimer's disease. Mice will be treated with mefloquine, a drug known for causing vivid nightmares, while researchers monitor their behaviors and brain activity using advanced imaging techniques.
