A Drug That Could Give You Perfect Visual Memory
Imagine if you could look at something once and remember it forever.
You would never have to ask for directions again. Now a group of scientists has isolated a protein that mega-boosts your ability to remember what you see.
A group of Spanish researchers reported today in Science that they may have stumbled upon a substance that could become the ultimate memory-enhancer.
The group was studying a poorly-understood region of the visual cortex.
They found that if they boosted production of a protein called RGS-14 (pictured) in that area of the visual cortex in mice, it dramatically affected the animals’ ability to remember objects they had seen.
Mice with the RGS-14 boost could remember objects they had seen for up to two months. Ordinarily the same mice would only be able to remember these objects for about an hour.
The researchers concluded that this region of the visual cortex, known as layer six of region V2, is responsible for creating visual memories. When the region is removed, mice can no longer remember any object they see.
If this protein boosts visual memory in humans, the implications are staggering. In their paper, the researchers say that it could be used as a memory-enhancer – which seems like an understatement.
What’s particularly intriguing is the fact that this protein works on visual memory only.
So as I mentioned earlier, it would be perfect for mapping. It would also be useful for engineers and architects who need to hold a lot of visual images in their minds at once. And it would also be a great drug for detectives and spies.
Could it also be a way to gain photographic memory? For example, if I look at a page of text will I remember the words perfectly? Or will I simply remember how the page looked?
I can’t see much of a downside for this potential drug, unless the act of not forgetting what you see causes problems or trauma.

I would imagine there has to be some form of trade off or we would already have the ability.
Take various forms of autism where perfect visual memory is present.
The sheer quantity of information would have to be offset by reduced brain function, also would you want to be able to pull up a perfect visual record of anything you had seen just because you were reminded of it? Imagine the effect on victims of violent crime or disaster. Not having any means of forgetting would be my idea of a personal hell.

Not necessarily. The human brain evolved to be most efficient for a lifestyle very different from modern day life. It may be that the only trade-off for having this enhanced memory is increased energy consumption (which our ancestors may not have been able to afford, but we today have plenty of extra cheap calories in our diets). That being said, there obviously needs to be much more research done to find out if there are any adverse effects. Also, this protein may only have the desired effects in mice, and not in humans.

wonder what the side effects would be?

cedley, you don’t know a thing about biology, do you? Unless a perfect memory were vital for our survival, it would not be selected for — just because it’s useful doesn’t mean it’s absolutely necessary.
And our body isn’t a zero-sum game — there’s no necessary negative for every positive.
That being said, it’s still possible that there’s negative side-effects — an inability to forget would sometimes be considered bad (inability to forget trauma, for instance) and the protein’s over-abundance could trigger other unwanted bodily functions (the likelihood of this is minimal, though).

Humans with perfect or near-perfect visual memory have existed, but I don’t know of any case where the person in question didn’t suffer some corresponding limitation in processing. For example: (not a primary source) http://blog.granneman.com/2008/12/04/a-russian-man-with-perfect-memory/
