A brief history of INA and ICOH SCNP: International Neurotoxicology Association and International Congress on Occupational Health Scientific Committee on Neurotoxicology and Psychophysiology.

Two international scientific societies dedicated to research in neurotoxicology and neurobehavioral toxicology are the International Neurotoxicology Association (INA) and the International Congress on Occupational Health International Scientific Committee on Neurotoxicology and Psychophysiology (ICOH SCNP). From June 5-10, 2011 these two societies held a joint conference in Xi'an China entitled the Xi'an International Neurotoxicology Conference, Neurotoxicity and Neurodegeneration: Local Effect and Global Impact. At the conference two featured talks presented a brief history of the two societies. This article is a synthesis and expansion of those two presentations. The history of INA and ICOH SCNP is described in relation to the antecedent events leading to the formation of the two societies, their parallel developments, the nature of the societies and their scientific conferences, and a brief description of some of their accomplishments. Together, the historical development of these two societies is an important component of the development of the scientific discipline of neurotoxicology.
