Neonatal rat research focuses on studying rats in the early stages of development, typically within the first few days or weeks of life. This research area is important in understanding the development and growth of rats, as well as in studying various physiological, neurological, and behavioral processes that occur during this critical period. Neonatal rat research is often used in fields such as developmental biology, neuroscience, toxicology, and pharmacology to test hypotheses, study disease mechanisms, and develop therapeutic interventions. Additionally, neonatal rat models are commonly used to study conditions such as neonatal hypoxia, neurodevelopmental disorders, and drug effects on the developing brain.
