The set of answers emitted by the organisms in response to a real or potential danger is called the Anxiety State. This state, of evolutionary importance, appears when a strong danger or risk is detected, and in response to ambiguous threat stimuli that could be of innate or learned nature. A low level of anxiety is beneficial for the animals as a fundamental resource of protection of the individual against physical and social dangers. The neural basis responsible by such states would be the oldest cerebral areas, preserved in many species, that are crucial for the control of the emotions, and whosemalfunctions lead to mood disorders. Many experimental models have been developed to help the study of behaviors and neural basis of the anxiety state, providing tools that collaborate not only to the therapeutics of pathologies, but also to the better understanding of the world of the emotions
