Which memory type relies on the hippocampus and medial temporal lobe for formation?

• A. Semantic memory
• B. Working memory
• C. Procedural memory
• D. Episodic memory

Answer: (D)

Episodic memory is the system that forms personal experiences, and its formation relies on the hippocampus and medial temporal lobe. The hippocampus acts as a binding hub that links the what, where, and when of an event into a single, context-rich episode. Because of this binding role, damage to these regions often disrupts the ability to form new episodic memories, even when other memory types remain intact. Semantic memory, by contrast, stores general knowledge and facts in cortical networks, while procedural memory relies on structures like the basal ganglia and cerebellum for skills and habits. Over time, memories can become less dependent on the hippocampus as they consolidate in the cortex, but the initial encoding is centered in the hippocampus and medial temporal structures.
