Final answer:
The hippocampus is responsible for the formation of new memories, spatial navigation, and plays a part in episodic memory processing, by projecting information to cortical regions for meaning and connection with other memories.
Step-by-step explanation:
The function of the hippocampus is crucial for the formation of new memories and plays a significant role in spatial navigation and the processing of episodic memories. Research has shown that the hippocampus is involved in various types of memory, including normal recognition memory and spatial memory, which are essential for tasks like object recognition and maze navigation. The hippocampus also projects information to cortical regions to give memories meaning and connect them with other memories, playing a part in memory consolidation: the process of transferring new learning into long-term memory.
With reference to the provided information, the correct answer to the student's question is A) Formation of new memories and spatial navigation.
