Neurogenic placodes are specialized regions of the embryonic ectoderm that are central to the development of the cranial sensory systems of vertebrates. These structures generate many of the sensory neurones of the head and also, in some instances, the associated sensory receptor cells. The neurogenic placodes have often been thought to share common pathways of development and to have evolved together. However, recent work has shown that this is not the case. The term 'neurogenic placodes' no longer seems to describe a cohesive group. Rather, the neurogenic placodes fall into a number of categories, and it is within each of these that the members share a common development and evolution.
神经源性基板是胚胎外胚层的特殊区域，对脊椎动物颅部感觉系统的发育至关重要。这些结构产生头部的许多感觉神经元，在某些情况下还产生相关的感觉受体细胞。人们常常认为神经源性基板具有共同的发育途径并且是共同进化的。然而，最近的研究表明并非如此。“神经源性基板”这个术语似乎不再能描述一个有凝聚力的群体。相反，神经源性基板可分为若干类别，每个类别中的成员具有共同的发育和进化过程。
