Rat research is a field of study that focuses on the biological, behavioral, and cognitive aspects of rats. Rats are commonly used as model organisms in scientific research due to their physiological and genetic similarities to humans. Researchers study rats in areas such as neuroscience, psychology, pharmacology, and genetics to better understand various biological processes and diseases. Rat research often involves experiments to investigate learning and memory, addiction, mental health disorders, and the effects of drugs or treatments. Overall, rat research plays a crucial role in advancing our knowledge of human health and behavior.
