Histamine is localized in the CNS of many invertebrate taxa by various methods. It is described to act as a neurotransmitter, neuromodulator, and neurohormone. Because of its distribution throughout these taxa it is tempting to forward the following hypothesis: Histamine acts as a neuroactive substance in all invertebrates. Its function as a transmitter of photoreceptors is restricted to arthropods. A special system of six large histamine-immunoreactive neurons exists exclusively in arachnids.
通过各种方法已确定组胺存在于许多无脊椎动物类群的中枢神经系统中。据描述，它可作为神经递质、神经调质和神经激素发挥作用。鉴于其在这些类群中的分布情况，很容易提出以下假设：组胺在所有无脊椎动物中均作为一种神经活性物质发挥作用。其作为光感受器递质的功能仅限于节肢动物。一个由六个大型组胺免疫反应性神经元组成的特殊系统仅存在于蛛形纲动物中。
