Abstract: The word “neuro” is originated from the classical Greek word “neuron” which means nerves and nervous system which plays a very essential role in functioning of different body parts of humans and animals.[1] Neurotoxins are those kinds of toxic substances which are when encountered with living body by what’s so ever way i.e. Cutaneous, Subcutaneous, Ocular, Muscular or Intravenous, causes maladaptive and detrimental behaviour of CNS (Central nervous system) which leads to evolve various diseases and ultimately death. Neurotoxicity is the direct or indirect ramifications of nerve cells and nervous systems which especially effects to the cellular metabolic processes on which CNS mutually depends.[2] Neurotoxicity is usually self-sustaining and rarely progressive when discontinued in exposure with body but there can be delay in between the contact time and the neurotoxic effects.[3]
