There exists preserved cross-species organization of the brain
MRI images of human and monkey
Cross-section of the brain in human and monkey
Hippocampi is preserved across species
Thalamus and midbrain preserved across species
Similar basal structures exist across humans and mice, as well
The major difference between mice and humans is the size of the cortex.
The greatest similarity is in brain organization.
Developmental organization of the brain
Similarities between species is also found in the developmental progress of the brain.
- Development of neural tube into spinal cord, then hindbrain, midbrain, and endbrain (including cortex)
- The cortex forms last and marks the major difference between humans and other lifeforms
