Problem:

Question 1: Discuss the similarities and differences between Parkinson's syndrome and Huntington's disease in terms of the anatomical and physiological bases, genetic determinants, and environmental influences. Why are Huntington's disease and Parkinson's disease considered extrapyramidal disorders?

Question 2: The role of the auditory cortex in hearing remained elusive as long as studies were performed using pure tones. What differences would you expect if natural noises were used such as those heard out in the woods (the snapping of a twig)? Also, what is the evolutionary advantage of "learned inattention" in our sensory systems? Relate this to the responsiveness of the auditory cortex
