This section covers the structure and topography of the cerebral cortex.

Readings: BCN 15; Read the web section: The Cerebral Hemispheres

Cortical Structure

Paleocortex:Simple layered pattern. Ex: Olfactory (Smell)

Archicortex:Three layered cortex. Ex: Hippocampus

Neocortex:

Mesocortex: Six layers which cover the limbic system

Ectocortex: Six layers over remainder of cerebrum

1. Tangential Layer Axons and Dendrites

2. External Granular Small Pyramidal and Stellate cells

3. External Pyramidal Medium Pyramidal Cells

4. Internal Granular Small stellate cells

5. Internal Pyramidal Medium - Large Pyramidal cells

6. Multiform Layers Multiform, some pyramidal and stellate
