Formation of new memories and spatial navigation are primarily functions of which structure?

• A. Hippocampus
• B. Thalamus
• C. Cerebellum
• D. Pons

Answer: (A)

The hippocampus is essential for forming new memories and for spatial navigation. It encodes fresh declarative memories—facts and events—by binding details into cohesive episodes and helps you map your surroundings with place-specific neural activity, supporting how you navigate new environments. Damage to this structure often produces anterograde amnesia, where new memories can’t be formed, and impairs the ability to learn and remember routes or locations. The thalamus mainly acts as a relay for sensory and motor information and supports attention and consciousness rather than memory formation. The cerebellum is key for motor learning and coordination, not the creation of new declarative memories. The pons, a brainstem region, is involved in basic autonomic and reflexive processes and in sleep–wake regulation, not memory formation.
