A patient with intact procedural memory but impaired ability to consciously recall facts and events has a deficit in declarative (explicit) memory. Which memory system and brain structure are MOST specifically responsible for consolidating declarative memories?

• A Procedural memory consolidated in the basal ganglia
• B Emotional memory processed by the cerebellum
• C Working memory maintained in the prefrontal cortex
• D Declarative memory consolidated via the hippocampus and medial temporal lobe ✓

Explanation

Declarative (explicit) memory consolidation depends critically on the hippocampus and medial temporal lobe. Patient H.M. demonstrated that bilateral hippocampal removal abolishes new declarative memory formation while sparing procedural memory (mediated by basal ganglia and cerebellum) and working memory (prefrontal cortex). The question specifically asks about declarative memory consolidation, making the hippocampus the correct structure.
