The Neuron- Up Close and Personal
Now we are looking at a cross-section of the forebrain of a rat.
This picture is a good illustration of the cerebral cortex at the frontal lobe of the brain. You can also see the body of the corpus callosum which is the structure connecting the two hemispheres of the brain. The white elliptical openings within the brain are ventricles. You can also see midbrain structures in this image. What else do you notice about this image??
Does this look different than what you saw in the human and monkey forebrains???? What is similar? What is different? Go back to the human forebrain. Or go back to the cat forebrain page. Do you notice any differences in the amounts of or degree of folding of the neocortex?
