Misson of NeuroIDSS: Radical increase of working memory for strategic autonomy

There is a cognitive bias leading to the lack of meaning, this is also due to the fact that we simplify numbers and probabilities to make it easier to think about them, and this also happens because there is a magical number 7+-2, which correlates with the size of working memory in the brain.
A 32-channel EEG brain-computer interface FreeEEG32 for measuring working memory has been designed and manufactured, and an alternating current stimulator FreetACS has been produced to increase working memory.

It is difficult to say whether there is much sense in increasing of working memory, but we can definitely say that without increasing of working memory, there is less sense.
