Hi sci, you can help me?
Recently I see that YouTube has been deleting many channels with his stupid biased algorithm.
I searching about a video of a guy that get transcranial magnetic stimulation, who ends up managing to improve their cognitive performance by turning off other parts of the brain, he does a test drawing a horse before and after and has significant improvement.
It also tests visual memory.

I would like to search with all people, please do not let this piece of knowledge fade away!
