The following tutorials include brief descriptive essays, 3D reconstructions, light micrographs, and electron micrographs. In addition, Dr. Josef Spacek's Atlas of Ultrastructural Neurocytology and Normal and Pathological Human Brain Anatomy feature hundreds of labeled 3D and EM images from the rat brain and human brain.

Read: the first reference to the Synapse Structure in the CNS (Palay SL, J Biophys Biochem Cytol. 1956).
