How The Animal Experimenting Contribute to OurUnderstanding of Human Brains - Essay Example Animal experiments (also known as vivisection) are defined in the Animals (Scientific Procedures) Act 1986 as any scientific procedures performed on a living animal likely to cause them "pain, suffering, distress or lasting harm." At present, the Act defines an animal as any animal with a backbone; plus the octopus. The approximated number of animals used for experimenting is almost 180 million every year worldwide. Though not every country keeps an estimate; in the USA, for example, 80% of animals like birds, rats, and mice used for research purposes are not included in official figures at all (Dr. Hadwen Trust, 2009). There are two things for which scientists use animals; one is for medical research and the other type. Clinical research is also an important type of research which is basically conducted on humans but it always requires preliminary test result after the completion of animal research studies. Researchers use animals for extensive purposes which involve poisoning; disease infection; wound infliction; use of skin or eye irritants; food, water or sleep deprivation; subjection to mental stress; brain injury; paralysis; surgical disfigurement; induced organ malfunction; genetic modification and associated physical deformity; burning; and electric shocks.
