A pyramid in your brain
Pyramidal cells live in the cerebral cortex, the wrinkly outer layer of your brain. They also live in the hippocampus, a part that helps make memories.
The cell body is shaped like a pyramid. One long branch points up toward the brain's surface. Shorter branches spread out from the bottom, and a long axon goes down.
Pyramidal cells are the most common kind of neuron in the cerebral cortex.
