The International Neurotoxicology Association (INA) is a scientific society whose members have interest and expertise in the discipline of neurotoxicology. The idea of forming INA was born in 1984, as a follow up to a NATO-sponsored meeting on Toxicology of the Nervous System. INA held its first meeting in the Netherlands in 1987 and has had continuous meetings every other year since then. INA is registered as a scientific society in the Netherlands, and is an affiliated society of IUTOX.
