Mnemonic

The human brain is the most complex physical entity in the universe.

A mnemonic device (memory device), is any learning technique that assists someone's memory.

Findings:

• The top participants of the annual World Memory Championships regularly demonstrate the ability to memorize hundreds of words, digits, or other abstract information units within minutes.

• Of the 23 athletes, 17 participated in a word learning task under fMRI conditions where they demonstrated their superior memory abilities compared to controls (70.8 ± 0.6 versus 39.9 ± 3.6 of 72 words correctly recalled 20 min after encoding; median, 72 versus 41; Wilcoxon signed-rank test, p < 0.001, r = 0.62).

• Brain changes: "Memory skills strongly differ across the general population; however, little is known about the brain characteristics supporting superior memory performance. Here we assess functional brain network organization of 23 of the world’s most successful memory athletes and matched controls with fMRI during both task-free resting state baseline and active memory encoding. We demonstrate that, in a group of naive controls, functional connectivity changes induced by 6 weeks of mnemonic training were correlated with the network organization that distinguishes athletes from controls."

• True to their name, the memory champions missed only two words on average when recalling the list 20 minutes later, whereas their controls missed nearly half.
