15. With what is a patient likely to have difficulty if they have damage to the hippocampus?

Answer: C

Explanation:

A patient is likely to have difficulty forming new memories if they have damage to the hippocampus.

Damage to the hippocampus primarily affects a person's ability to form new memories, particularly declarative memories, which are essential for learning new information.

A) Balancing the body

This option is incorrect because balancing the body is primarily controlled by the cerebellum and other areas of the brain associated with motor control, not the hippocampus. Damage to the hippocampus does not directly impact the vestibular or motor systems responsible for balance.

B) Regulating body temperature

Regulating body temperature is managed by the hypothalamus, which oversees homeostatic functions in the body. The hippocampus does not play a role in thermoregulation, making this option incorrect.

C) Forming new memories

This option is correct as the hippocampus is critically involved in the formation of new memories, particularly episodic and declarative memories. Damage to this area can lead to anterograde amnesia, where the individual struggles to create new memories after the injury.

D) Breathing

Breathing is controlled by the brainstem, specifically the medulla and pons, which regulate autonomic functions. The hippocampus does not influence respiratory control, rendering this option incorrect.

Conclusion

The ability to form new memories is directly associated with the function of the hippocampus, making option C the definitive correct answer. In contrast, the other options relate to different brain structures and functions that are not impacted by damage to the hippocampus, demonstrating why they are incorrect in this context.
