The described alterations in synaptic strength and hippocampal remodeling are linked to which memory system?

• A. Procedural memory
• B. Declarative memory
• C. Working memory
• D. Short-term memory

Answer: (B)

Synaptic changes and remodeling in the hippocampus are hallmark processes of forming explicit, consciously recalled memories. The hippocampus is essential for declarative memory, which includes facts and events (semantic and episodic memory). When synapses strengthen through mechanisms like long-term potentiation, and the hippocampus undergoes structural changes during consolidation, it supports the encoding and stabilization of these explicit memories. Other memory systems rely on different brain circuits: procedural memory hinges on the basal ganglia and cerebellum for skills and habits; working memory involves frontal with parietal networks for holding and manipulating information; and short-term memory refers to temporary storage that's often tied to working memory processes. So the described hippocampal synaptic strengthening and remodeling best align with declarative memory.
