Cephalization of the Neurotube produces the brain

• Cephalization of the Neurotube produces the brain

• Neuron column plan of spinal cord remains up to diencephalon but adds:
• “Gill Arch” motor components and “special senses”.
• Centers of “Supraspinal Control”
• Cortex, basal ganglial, cerebellar cortex and brainstem centers
• Pathways pass through
• Ascending and descending
• to and from subcortical nuclei
• Pathways begin in brainstem
