Final answer:
Lesions of the hippocampus can lead to dramatic deficits in explicit memory.
Step-by-step explanation:
The deficits in explicit memory can be seen following lesions of the hippocampus. The hippocampus plays a crucial role in processing explicit memories, which are consciously recollected memories of facts and events. Damage to the hippocampus can result in significant impairments in forming new explicit memories while leaving other types of memory, such as implicit memory, intact.
