This review presents a study on the anatomical and histological features of the central nervous system in rose-ringed parakeets. The study involved nine healthy pairs of parakeets divided into three groups: Juvenile, Breeding Adults, and Non-Breeding Adults. Macroscopic and microscopic analyses were conducted on the brain, spinal cord, and optic lobes, along with measurements of body weight and dimensions. The results showed that adult parakeets during the non-breeding season exhibited the highest weights and dimensions in the body, brain, cerebrum, cerebellum, and eyes, while these parameters were lowest in juveniles. The study also highlighted the extensive optic tracts in parakeets, suggesting their high visual activity. Moreover, these findings provide major contribution into the central nervous system characteristics of rose-ringed parakeets and their developmental changes throughout different life stages. In addition, this study conducted to investigate the anatomical and histological features of the central nervous system in rose-ringed parakeets. The research involved nine pairs of healthy parakeets, categorized as Juvenile, Breeding Adults, and Non-Breeding Adults. The brain, spinal cord, and optic lobes were examined through macroscopic and microscopic analyses, while body weight and dimensions were recorded. The study found that adult parakeets during the non-breeding season exhibited the highest weights and dimensions in various anatomical structures including the body, brain, cerebrum, cerebellum, and eyes. Conversely, juveniles showed the lowest measurements. Additionally, the parakeets displayed extensive optic tracts, indicating their heightened visual activity.
