WebPTA selectively visualizes the proteinacious contents of AZs and postsynaptic densities (PSDs); the synaptic plasma membrane is not stained. Whereas the PSD appears as a regular, dense band, the AZ forms dense projections (DPs) that protrude approximately 50 nm into the presynaptic terminal. Web12 Jul 2024 · What is a Postsynaptic Neuron?
