Is There a Way to Accelerate the Rate of Learning?

Is there a way that you could hack the electrical signals in your brain using like headsets or implants to make yourself smarter or improve your memory? There are many, many studies that have looked into accelerating the rate of learning. The problem is that as with the rest of the electron, there's so much about bioelectricity that hasn't been characterized. So I think right now there are really amazing implications and there's a lot of potential.
