  Ibotenic acid (CAS NO.2552-55-8) is a powerful neurotoxin ,thus it is used as a "brain-lesioning agent". When "injected" directly into the brains of mice and ratsand, Ibotenic acid has shown to be highly neurotoxic.

 Ibotenic acid is a chemical compound that is naturally occurring in the mushrooms Amanita muscaria and Amanita pantherina, among others. In 1960's, Ibotenic acid was originally isolated from Amanita ibotengutake in Japan.
