Dr. Friedman’s research explores how social factors alter neural circuit’sresponses to chronic and acute stress, and influence susceptibility or resilience to neuropsychiatric disorders such as depression, PTSD and anxiety. A crucial question her lab addresses is how positive socialization can bring about changes in the brain that that ease the symptoms of neuropsychiatric disorders. Utilizing cutting-edge cell-type/circuit specific manipulations and electrophysiological recordings, her lab investigates the neuronal adaptations that underlie these beneficial and protective effects. The goal of this research is to provide targets for mechanistically driven therapeutics for mood disorders.
