Final answer:
The cerebellum is the brain structure most involved in creating implicit memories, such as procedural memories and conditioned responses like eye-blink conditioning in rabbits. Option D is the correct answer.
Step-by-step explanation:
Implicit memories, which include procedural memory, motor learning, and classical conditioning, are not stored in the same way as explicit memories. The brain structure most associated with implicit memories is the cerebellum.
While the hippocampus is key for encoding new explicit memories and the amygdala is important for emotional memory, the cerebellum is essential for processing procedural memories, like how to play an instrument or the conditioned eye-blink response. Research involving damage to the cerebellums of rabbits showed that they weren't able to learn a conditioned eye-blink response, which clearly indicates the cerebellum's role in the formation of implicit memories.
Thus, when considering the options provided:
A) Hippocampus
B) Amygdala
C) Frontal lobe
D) Cerebellum
The correct answer is D) Cerebellum for its direct involvement in creating implicit memories.
