They concluded that "there are connections between the central nervous system and the immune system."
Psychoneuroimmunology is a generally new discipline which manages central nervous system and immune system collaborations. By exhibiting that one could traditionally condition the concealment of an immunizer reaction to an antigen, Ader and Cohen had demonstrated that there must be associations between the central nervous system and the immune system. In the late 1970s and mid 1980s, researchers found that the ANS is connected to immune framework structures, for example, the thymus organ, and that safe cells have receptors for and can deliver stress.
