International Society of Nephrology research, diagnosis, treatment, and prevention of kidney disease. The ISN has over 9,000 professional members from more than 126 countries. In addition, the ISN closely collaborates with over 75 national and regional nephrology societies around the world, representing about 20,000 professionals. The ISN continues to develop and consolidate several programs, initiatives and partnerships that will help to further deliver on its two overarching goals: reducing the incidence and impact of kidney disease worldwide, and making the ISN the leading international organization for all issues related to the science and practice of global nephrology.

Methods used to study memory able to show that food-caching birds have much larger hippocampus’ than non food-caching birds. Without techniques such as cell labeling, neuronal staining and careful post mortem analysis, these comparison studies would be impossible. Songbirds are excellent animal models for studying learning and auditory memory. These birds have highly developed vocal organs, which give them the ability to create diverse and elaborate birdsongs. Neurotoxic lesions can be used to study how specific brain structures are key for this type of learning and scientists can also manipulate the environment in which these birds are raised. In addition, with functional MRI the response
