Knowing how to differentiate, when a system is healthy or sick; it can be the key to find innovative solutions on how to cure or prevent any disease, that is why it is necessary to perform animals testing. Since they are used to find the treatment of biological conditions, which are the result of the deterioration of the functions of the human body, those that affect the psyche and contribute to crash both, the human behavior and personality, there are also others that have a great impact at a social level, therefore, it is necessary to use the animals testing, to find the treatment of biological, psychic diseases and those that have a great social impact. Animals are used to develop the treatment for biological conditions and every time the experts find the link between a specific gene and the disease, immediately, they determine what the function of that gene is in a model organism. The aforementioned can become, the key in the way to determine, the causes of the diseases. It can also be extremely useful for scientists to test certain diagnostic tests and treatments that have been demonstrated in clinical trials. The mice, for example, have used, as a model, to investigate the viral biology and the treatment of AIDS-HIV, Asthma, and diseases of the joints and bones. Some people …show more content…
Certain models have had to be developed for the use of animals, in the study of mental illnesses reflects, the model's ability to recapitulate specific anatomical, biochemical or behavioral characteristics of diseases in humans such as, schizophrenia, Alzheimer's and Parkinson's Disease and all of them have shown the efficacy of those researches. But there are some experts who think that the phylogenetic development of the Neurologic System does not allow to determine all the physiological behavior in the human
