Exam 11: Learning, Memory, and Amnesia

It is widely believed that damage to the hippocampus is the major factor in the difficulties that medial temporal lobe amnesics have in recognizing objects. Why? What does relevant research on monkeys and rats suggest?

The cerebellum has been found to play an important role in
