Department of Psychiatry Provides Mentorship and Hands On Research Experience to Help Young Physician-Scientists Build Successful Careers in Psychiatric Neuroscience
Early exposure to cutting-edge research and hands-on experiences in laboratories is crucial to preparing the next generation of physician-scientists for successful careers in psychiatric neuroscience research. It also can lead to transformative discoveries that ultimately improve the lives of individuals with mental illness. The Department of Psychiatry is an international leader in helping young scientists learn...
Freyberg and Colleagues Bring Cryoelectron Tomography Imaging to Intact Human Cells and Explore the Biological Consequences of a Mutation that Causes Mitochondrial Disease
Mitochondrial diseases are a group of inherited and severe multiorgan disorders that stem from mutations affecting the proper functioning of mitochondria, the “power plants” of cells that generate the majority of the energy needed for metabolic processes. Due to its high energy requirements, the brain is especially vulnerable to energy shortages, and therefore neurological symptoms are common in mitochondrial...
Hot Publication – Freyberg et al.
Findings by Dr. Zachary Freyberg et al. challenge the existing dogma about how dopamine-releasing neurons communicate, showing that they can change the amount of dopamine released as a function of their overall activity. Malfunctioning of this mechanism could have major implications for many dopamine-related diseases, including schizophrenia, Parkinson’s disease, and addiction. The basics of dopamine signaling...
MindScapes Art Exhibit Aims to Reduce Mental Health Stigma
Mindscapes, an exhibit of artwork created by Pittsburgh brain researchers and people who have experienced mental illness, was held at The Image Box as part of the Unblurred: First Fridays on Penn monthly art crawl. Drs. Lizzie Manning and Micah Shelton, researchers from the Translational Neuroscience Program (working with Dr. Susanne Ahmari and Dr. Ryan Logan, respectively), held the event during national Mental...
