Fig. 1.3.01. The perikaryon of the pyramidal neuron. The black rectangle outlines an area of axo-somatic synapses detailed in Fig. 1.6.02. N - nucleus. Scale = 5 µm. Inset - The pyramidal cell in semithin (0.5 µm) epoxy-resin section as viewed by light microscopy. This type of imaging of tissue processed for electron microscopy offers high resolution views intermediate between conventional light and electron microscopy. (Mouse, neocortex).
