Which part of the brain matures around the age of two and is crucial for the storage of memories?

The hippocampus is the part of the brain that matures around the age of two and plays a crucial role in the storage and processing of memories. This structure is integral to the formation of new memories and is particularly essential for declarative memory, which involves remembering facts and events. During early childhood, significant developments occur in the hippocampus that enable young children to begin forming more complex and long-lasting memories.

The maturation of the hippocampus aligns with significant milestones in cognitive and memory development seen in toddlers, such as the ability to recall past events and learn from their experiences. This is why the hippocampus is vital for memory function, specifically in the early years of life.
