Final answer:
The correct answer to the patient's difficulty in remembering facts and long-term memories is the temporal lobe. The temporal lobes of the brain, particularly structures like the hippocampus within the medial temporal lobe, are crucial for the storage and retrieval of long-term memories, as demonstrated by the famous case of patient H.M. The option (C) is correct.
Step-by-step explanation:
The temporal lobe of the cerebrum is likely involved if a patient is having difficulty remembering facts and recalling long-term memories. The storage and retrieval of long-term memories are functions heavily associated with the temporal lobes, especially with the roles of the hippocampus and related medial temporal lobe structures. The case of patient H.M., who had both his left and right temporal lobes removed and suffered from significant memory impairments, dramatically underscores the importance of these regions in memory function. H.M. could remember many events that occurred before his surgery and retain short-term memories, but he was unable to form new long-term episodic memories due to the removal of medial temporal lobe structures.
Therefore, the correct answer to which part of a patient's cerebrum is probably involved when having difficulty remembering long-term memories is C. Temporal lobe.
