Switches in the Brain? A Potential Mechanism for Long-term Memory Storage
We forget often. But some memories last a lifetime. Thismeans that our brain is capable of protecting memories foryears. This is a remarkable feat given that the biochemicalhardware involved in creating new memories is a hostile placefor its storage. What are the challenges involved? And whattype of biochemical mechanisms may overcome them? Thisarticle explores a major hypothesis that molecular switchesmay be behind our remarkable ability to remember for a lifetime.
