Fig. 1.5.32. A dense (saturated) 3D reconstruction of a volume of  hippocampal cortex (stratum radiatum 6 x 6 x 5 µm - left) and cerebellar  cortex (molecular layer 2 x 2 x 2 µm - right). Axons (green) are  randomly oriented in the hippocampal cortex but mostly parallel in the cerebellar  cortex. (Dendrites colored in yellow or gray, astroglia in blue.) Edges of  scale cubes = 1 µm - left, 0.2 µm - right.
