Abstract:
The submicroscopic structure of the postsynaptic membrane and the snbsynaptic dense body in the supraoptic nucleus of the hypothalamus of rat were studied. It was found that the subsynaptic dense body and postsynaptic membrane were connected by fine filaments. The subsynaptic dense body was closely related to the postsynaptic membrane and its submicroscopic configuration was complicated. In spite of the obvious differences existing between the subsynaptic dense bodies, nevertheless a typical one was described in this nucleus.It is of interest to note that most subsynaptic dense bodies were mainly encountered within the postsynaptic element of Gray's Type Ⅰ synapse, thus the authors postulated that the subsynaptic dense body would play an important role in the excitatory synapse.
