cell in Chapter 1. We can get a
better idea of the distribution of pyramidal cells within the
cortex in another drawing from 
Ramón y Cajal's Histologie (to 
the left), which shows perhaps 
1 percent of pyramids instead of 
only one or two cells.

A Golgi-stained section from the 
upper layers, 1, 2, and 3, of the 
visual cortex in a child several 
days old. Black triangular dots 
are cell bodies, from which 
emanate an apical dendrite 
ascending and dividing in layer 
1, basal dendrites coming off 
laterally, and a single slender 
axon heading straight down.
