How the neural tube of embryonic chordates forms
How differentiation of the neural tube produces neurons
That immature neurons migrate to a final location
That chemical stimuli influence the growth of axons to other parts of the body
Multiple synapses form with developing neurons
Unused synapses are lost
That neural pruning removes unused neurons
How plasticity allows the nervous system to change
How does the neural tube develop in an embryo?
How are neurons produced from the neural tube?
Outline the steps of neural tube development:
State when neural tube development begins in a human embryo:
How do immature neurons reach their final location?
What is meant by the term “neural migration”?
How do synapses develop and what happens to those not used?
What is the consequence of plasticity in the nervous system?

The anterior part of the neural tube forms the brain
The different parts of the brain have specific functions
The autonomic nervous system controls involuntary processes
The cerebral cortex forms a large part of the human brain and is folded so that it will fit within the cranium
That cerebral hemispheres are responsible for higher order functions
That the left hemisphere receives input from the right side of the body and the right side of the visual field in
both eyes and vice versa
 The left hemisphere controls the right side of the body and vice versa
 Large amounts of energy are needed for brain activity

How does the brain develop from the neural tube?
What are the functions of the different parts of the brain?
Which aspects of the body are controlled by the ANS?
Distinguish between the Parasympathetic and the Sympathetic Nervous systems:
How has the cerebral cortex evolved in humans?
Which area of the brain is responsible for higher order functions?
Name 2 higher order functions and the area of the brain with controls those functions:
What are the different roles of the left and right sides of the brain?
How is the activity of the brain powered?
What techniques are used to investigate the activity of the brain?
If a person suffered an injury to the Broca’s area of the brain, what functions might be altered?
