The postsynaptic density (PSD) is a protein dense specialization attached to the postsynaptic membrane. PSDs were originally identified by electron microscopy as an electron-dense region at the membrane of a postsynaptic neuron.
Synapses on somas are termed axosomatic synapses; those on dendrites are termed axodendritic; and those on other axons or boutons are axoaxonic. The fiber's bouton is called the presynaptic element and the structure it contacts is the postsynaptic element. A schematic diagram of a synapse is shown in Figure 13-1A. The pre- and postsynaptic elements are separated by a space 15-200 nm wide, known as the synaptic cleft.
