They do so by traveling from the so-called presynaptic neuron across a tiny gap to bind to receptors on the postsynaptic neuron's cell membrane. 它们从所谓的突触前神经元出发，通过神经元之间的微小间隔，而与突触后神经元细胞膜上的受体相接。
Phosphorylation of postsynaptic density proteins remains a largely unexplored mechanism in activity-dependent regulation of dendrite development and synaptic function. 在树突发育和突触功能活性依赖的调节过程中，突触后致密蛋白磷酸化的机制仍然是未知的领域。
