Brain injury survivors with hippocampus damage may experience
Correct answer: B. Difficulty in recalling old memories
- A. Vision and perception problems
- B. Difficulty in recalling old memories
- C. Inability to understand spoken or written language
- D. Trouble with emotional reactions and decision-making
Explanation
The hippocampus is a critical region for memory formation and retrieval, especially in transitioning memories from short-term to long-term storage. Therefore, damage to the hippocampus can lead to difficulties in recalling old memories, making Option B the correct choice. Option A is incorrect because vision and perception are controlled by different parts of the brain, such as the occipital lobe. Option C is incorrect as language comprehension is linked to Wernicke's area. Option D is incorrect because emotional reactions and decision-making are more associated with the amygdala and prefrontal cortex.

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
