To answer the question regarding the structure most greatly implicated in Long-Term Potentiation (LTP), we need to consider the roles of the listed brain structures in memory and learning.

1. Amygdala: Primarily involved in emotional responses and has a role in memory, particularly emotional memories, but is not the primary structure related to LTP.

2. Para-hippocampal gyrus: Involved in memory encoding and retrieval, but again, not the primary region associated with LTP.

3. Hypothalamus: Primarily regulates homeostasis and does not have a significant role in LTP.

4. Hippocampus: This structure is well-known for its critical role in the formation of new memories and is the most extensively studied region regarding LTP. It is essential for synaptic plasticity, which is the cellular mechanism underlying LTP.

5. Pons: Functions primarily in regulating sleep and arousal; not directly implicated in LTP.

Conclusion

Based on the functions and implications of these structures, the answer is D. Hippocampus, as it is fundamentally implicated in the processes of Long-Term Potentiation and memory formation.
