The development of a Cognitive Activation Theory of Stress: from limbic structures to behavioral medicine.

This paper attempts to argue for a consistent trend in a research spanning more than fifty years, starting in the exciting neuroscience environment in the Anatomical Institute at the University of Oslo, and presently to be found as an active behavioral medicine unit in Bergen. The most comprehensive theoretical result is a systematic and formalized theory of stress, referred to as the Cognitive Activation Theory of Stress, CATS for short (Ursin & Eriksen, 2004). There are many roots, many related issues, and many scientists involved. There is no way to produce a complete story. However, one aspect is beyond discussion, the story started in the Neurophysiology laboratory in Oslo.
