Silver impregnation Golgi staining reveals the complex dendritic arbor and downward extending axon of a layer V pyramidal neuron in the cortex. Dendritic spines are shown in the inset. The surface area of this neuron can be upwards of 10,000 times greater than that of other mammalian cell types such as fibroblasts or epithelial cells as indicated by the small black dot to the left.
