- Allocortex
- Neocortex (also called Isocortex)
What are the two divisions of the allocortex?
- Paleocortex: olfactory tubule, piriform complex
- Archicortex: hippocampus, amygdala
What are the three layers of the hippocampus?
- dendrites
- pyramidal cell somas
- axons
How many layers of the neocortex are there?

six layers
What is Layer 1 of the neocortex called and what comprises it?
- Molecular Layer
- Axons and Dendrites
What is Layer 2 of the neocortex called and what types of cells exist there?
- External granule layer
- small round cells
What is Layer III of the Neocortex called and what type of cells does it contain?
- External Pyramidal Layer
- small pyramidal cells
What is Layer IV of the Neocortex called and what does it do?
- Internal Granule Cells
- small round cells that do lots of interconnecting
What does Layer is layer V of the neocortex called and what type of cells are in it?
- Internal Pyramidal Layer
- Large Pyramidal Cells
