Could be nice to recall from memory what we saw, listen or anything from our life experiences in any time.
This is possible but still not well documented, was the Doctor Strange Movie with his mention about photographic memory what makes me think again about it.
This article is a teaser, an exploration of any human ability and technique to improve human memory.
Could memory revive any experience or perception in just seconds and afterward reproduce a correct and detailed picture of it?
Stephen Wiltshire can vividly recall an entire city from his own memory. He was diagnosed with autism, but years later as a Savant thanks to his amazing memory.
He has drawn Tokyo, Rome, Hong Kong, Frankfurt, Madrid, Dubai, Jerusalem and London on giant canvasses. When Wiltshire took a helicopter ride over Rome, he drew it in such great detail that he gave life again to the Pantheon, including the exact number of column.
Richard Wawro as Stephen was also an autistic savant artist with notable memory for his landscapes made in wax oil crayon.
Akira Haraguchi Not a Savant, He tried to beat the Guinness record reciting 100.000 Pi decimals in a well-documented event but still not recognized by Guinness records. He used a mnemonic system he developed, which assigns ‘kana’ symbols to numbers allowing the memorization of Pi as a collection of stories.
The same system was developed by C. S. Lewis to assign letters from the alphabet to numbers, creating stories to memorize numbers, this system preceded the system above which Haraguchi developed.
Example:
0 => can be substituted by o, ra, ri, ru, re;
1 => can be substituted by a, i, u, e, hi, bi;
The same is done for each number from 2 through 9. His stories are what he used to memorize pi.
Leslie Lemke, Tony DeBlois and Derek Paravicini Everyone with incredible music memory, with Leslie Lemke being the more impressive he can remember and play back a musical piece of any length flawlessly after hearing it once. The three are linked to brain damage because premature birth, excessive use of oxygen and posterior blindness (please don’t try it at home lol)
A second part will come soon, there are interesting techniques and also neurobiological experiments and studies, that need to be reviewed.
Note that there are many cases of people remembering weather, food or clothes and calendar related event after brain damage, also the Rain Man case is notable about remembering books.
