The term "neurotoxic substances" specifically refers to a category of compounds known to produce harmful effects on the nervous system. These substances can disrupt the normal functioning of neurons and may cause symptoms ranging from mental confusion to paralysis or even death. Neurotoxicity is a well-documented phenomenon in various fields, including medicine, pharmacology, and toxicology, highlighting the importance of identifying and understanding these compounds.

While alkaloids can indeed exert toxic effects on various biological systems, including the nervous system, they are not exclusively classified as neurotoxic agents. They represent a broader group of compounds that can have both therapeutic and toxic effects, depending on the context and dosage. Terpenes and esters are primarily known for their roles in aroma and flavor and are generally not categorized as neurotoxic. While they can influence mood or perception when used in aromatherapy, they do not directly cause toxic effects on nervous tissue.
