Understanding the physical basis of human memory will enable therapies to both enhance youthful memory and reverse its decline with age. From ScienceDaily, an example of present investigations into the biology of memory: "We found one of the key proteins involved in the process of memory and learning. This protein is present in the part of the brain in which memories are stored. We have found that in order for any memory to be laid down this protein, called the M3-muscarinic receptor, has to be activated. We have also determined that this protein undergoes a very specific change during the formation of a memory - and that this change is an essential part of memory formation. In this regard our study reveals at least one of the molecular mechanisms that are operating in the brain when we form a memory and as such this represents a major break through in our understanding of how we lay down memories. This finding is not only interesting in its own right but has important clinical implications. One of the major symptoms of Alzheimer's disease is memory loss. Our study identifies one of the key processes involved in memory and learning and we state in the paper that drugs designed to target the protein identified in our study would be of benefit in treating Alzheimer's disease."
