One of the very interesting types of cells that we find in the cerebral cortex is call the pyramidal neuron, and it's called that because the cell body is shaped something like a little pyramid. And from that cell body grow out a series of dendrites, and from the apex of the pyramid is one rather thick, stout dendrite that we call the ______ dendrite because it grows out from the apex towards the surface of the brain. At the base of the pyramid are a variety of other dendrites called basal dendrites. That single () dendrite might have special properties
