ABSTRACT
The nervous system has numerous functions including coordination and regulation of homeostasis of systems such as the respiratory, digestive, circulatory, and endocrine systems to name a few. The nervous system also mediates movement and provides mechanisms for sensory perception. In addition, innate and acquired behaviors originate within the nervous system as well as higher cognitive functions, which de•ne personality and enable learning, memory, and emotion. As a result, toxins that affect the nervous system can have broad and devastating effects across many physiological and psychological domains.
