Correct Option: C
Explanation:
  • The limbic system is the portion of the brain that deals with three key functions: emotions, memories, and arousal (or stimulation).
  • The components of the limbic system include Amygdala, Hippocampus, Septal nuclei, thalamus, hypothalamus, basal ganglia.
  • The posterior surface of the adult midbrain is characterized by four elevations collectively called the corpora quadrigemina. It is not a part of the limbic system.
  • Hence the brain structure is not considered to be part of the limbic is Corpora quadrigemina.
  • So, the correct answer is 'Corpora quadrigemina'.
