Word origin

The term 'neurotoxin' combines the prefix 'neuro-', derived from the Greek word 'neuron', meaning 'nerve', and 'toxin', which comes from the Greek 'toxikon', referring to a poison or venom. The concept of neurotoxicity has its roots in early medical and psychological research as scientists began to explore how poisons could affect the nervous system. Early studies, particularly those involving animal models, revealed a variety of substances that hindered nerve function. The expansive research on neurotoxins gained momentum in the 19th and 20th centuries, particularly with the discovery of botulinum toxin and its effects on the human body. Advances in toxicology and pharmacology have since uncovered numerous neurotoxins, leading to important findings in medicine, including the potential use of certain neurotoxins in treating various conditions, such as muscle spasms and migraines. The understanding and classification of neurotoxins continues to evolve with ongoing scientific investigation.
