This is a pyramidal neuron, so named for the pyramid-shaped body at the center of this drawing, from the cerebral cortex of a human. This outermost layer of the brain integrates information from sensory organs, commands movements and is the hub for higher brain functions, such as consciousness. In his drawing, Cajal gives the branches or dendrites different weights to show how the neuron extends in three-dimensional space. It’s likely that this represents a sort of idealized portrait of a pyramidal neuron, a synthesis of many observations.
