Salomon's memory, "savant" seems like unlimited. He repeated 30, 40 even 70 numbers , words or voices after one reading and he could tell them backwards, on demand of wish. As well many of parts of Dante Divine Comedy. Also months and years later he could all that he taught or read call back in memory together with circumstances in which he was reading.

Stephen and Edelson from Center for the Study of Autism from Oregon are describing "savant syndrome" as one of most fascinating cognitive phenomenon of psychology studies and people diversity. Syndrome was first described by doctor Down in 1887, and it became wide known after with Oscar awarded movie Rain Man. Expression is relating to individuals- some of them are autistics, others can have different types of brain damage or other disturbances in development- that have above average abilities. Some are saying that we will never understand human cognition and memory , till we wont understand "miracle talents"of savant. Reason, why some people have this abilities is unknown.

Risky manipulation For normal people are scientists developing medicines that would help improve our memory and sharpen our thoughts. Memory just to be total riddle. Explorers have done many studies with which they help explore mechanisms that are enable complex function of memory. But how far are we aloud to go in manipulation with our "gray cells"? The subject is attractive, because those that are normally forgetting stuff, constantly fighting with that memory weakness, so they have to again and again look for telephone number of doctor, they quickly forget names of friends or they find it hard to learn some other language. All this come on surface after we become 20 years old and it is more obvious after 40. The lost of read, experienced or learned content can be very painful in our modern world that is based on richness an power of data.

From Antic times we are fighting forgetfulness with help of memo techniques for memory training. In last times we are able to try it in different ways. Neurobiologist and psychologists have strength their knowledge in last decade exponentially. They explored ways of data storage, they defined features of forgetting and they defined cartography of brain functions. On that way they tried also biomedical possibilities how to manipulate with processes between and in neurones, that are interceding our memories, so they would improve memory in sick or healthy individuals. To awake exhausted memory, to sharpen and make faster our memory, so children and adult would preform better concentration and studying. Nobel prize winer E. Kandel thinks, that this kind of interfere into our brain would mark history same or stronger as genetics marked end of 20 century or mechanization marked industrial revolution. So called smart drugs and stimulative substances as caffeine or biloba are part of everyday life, even if their effect is mostly unproven. Which don't hold back their protagonists when they sell brain booster formula (mostly in states), that includes also mix of amino acids, vitamins, lipids, lecithin , hormones and so on.
