Measurement of PSD length and HD in non-perforated and perforated synapses. Electron micrographs were selected from two sets of five serial sections each to depict the synapse types. a A unique non-perforated synapse and b a perforated synapse. The sections are numbered 1–5 to show their position in the series. The postsynaptic spine of unique synapses is indicated in green. PSD length (magenta line) and HD (orange line) were measured for each non-perforated synapse and in all the sections where it was visible for the perforated synapse. Scale bar = 250 nm
