1969年Peters等[1]首先报道了一种突触后致密物质含有一个或多个孔洞的突触，现在将这类突触统称为穿孔突触（perforatedsynapse，PS），并将突触后致密物质完整的突触称为非穿孔突触（non－perforatedsynapse，NPS）、穿孔突触的超微结构特征是：突触接触区面积较大，在垂直于
In 1969, Peters et al. [1] first reported a synapse with one or more holes in the postsynaptic dense substance. Now, these types of synapses are collectively referred to as perforated microsynapse (PS), and the postsynaptic density The intact synapses are called non-perforated synapse (NPS). The ultrastructural features of perforation synapses are: the area of synaptic contact is larger,
