Old brain parts are what exist in
very young children, and the
new brain develops later
The old brain developed first
according to evolution
The old brain becomes more
active as we grow older
The new brain deals with new
information, while the old brain
deals with information gathered
when we were children
The old brain is most affected by
age deterioration (dementia)
while the new brain remains
unaffected

A spinal reflex occurs only in response to
extremely stressful stimuli
In a spinal reflex, the spine moves the
muscles in response as soon as the
sensory information reaches the spine
while usually the impulse must reach the
brain before a response
In a normal sensory/motor reaction, the
spine transmits the information through
afferent nerve fibers, while reflex
reactions are transmitted along special
efferent nerves
Spinal reflexes are part of the central
nervous system response, while normal
sensory/motor reactions are part of the
peripheral nervous system
Spinal reflexes occur only in animals
because humans are born without
instinctual responses

An electric charge is created in the
neuron, the charge travels down the cell,
and chemicals are released that cross the
synapse to the next cell
A chemical change occurs within the cell,
the change causes an electric charge to
be produced, and the charge jumps the
gap between the nerve cells
The electric charge produced chemically
inside a group of neurons causes
chemical changes in surrounding cells
Neurotransmitters produced in the
hindbrain are transmitted to the forebrain,
causing electric changes in the cerebral
cortex
Neural transmission is an electrochemical
process both inside and outside the cell

Mr. Hawthorne is a 39-year old male who has been brought into your neurology
clinic by his wife. She has become increasingly alarmed by her husband’s behavior
over the last four months. His list of symptoms include: increased appetite, body
temperature fluctuations, decreased sexual desire, poor balance when walking and
standing and a general lack of coordination. Which two parts of the brain would you
predict are being affected by the tumors?
