Learned Helplessness

Researchers have developed a preclinical model of depression using rats and mice, where the animals are placed in water to observe how long they will swim before giving up. This behavior, known as learned helplessness, provides valuable insights into the mechanisms of depression, paralleling human experiences where individuals may lose hope and stop envisioning a positive future. By testing various drugs, scientists can assess their impact on the animals' resilience in this distressing scenario.
