I was watching "The brain that changes itself" on YouTube to better understand neuroplasticity and how this Lenire device might work. But I am pretty confused.
In the video, people get input via their tongue and the brain processes it using the tactile channel rather than the usual route. It seems you should also be able to learn to hear with your tongue the same way, say, with a tongue tip device that "plays" simple songs you are already familiar with while you get visual clues to the tune, a bouncing ball, scrolling lyrics, images of instruments being played, etc.
Why simultaneously pump in sound to the ears? Won't that make it much much more difficult to learn to hear with your tongue?
And, is there not also some annoying timing delay between the ears sounds and the tongue stimulation?
I really don't get it why they do this bi-modal neurostimulation.
