17) parkinson’s disease affects the cerebral basal ganglia, resulting in tremors in limbs,
slowness in beginning and completing movements, and other abnormalities of muscle
control. the specific population of neurons involved degenerates and thus fails to
produce the neurotransmitter dopamine. an obvious treatment option to try is to
administer dopamine, yet this is completely ineffective at alleviating the symptoms.
propose a reason why this treatment fails, and a related alternative to address the
dopamine deficit. (hint: think about how the brain protects itself from chemicals in the
blood.)
