Just spoke with @AdamMarblestone and he mentioned some techniques building towards noninvasive deep brain stimulation. You can have two different high-frequency electrodes, each too fast for neurons to pick up, but which interfere & resonate at a slower frequency, so...

they don’t stimulate neurons near the scalp where the electrodes sit, but do stimulate them at an intersection point deeper inside the brain.

Alternatively, ultrasound waves in a magnetic field can create an electric current; so if you focus ultrasound at a point inside the brain, and have an ambient magnetic field around, you can get focused deep brain stimulation.

Maybe not deep brain stimulation, but Halo Neuroscience is doing motor cortex stimulation using tDCS for athletes; but you’ve probably heard of them

I didn’t know that specific company, thanks!

Current follows least resistance, and wouldn't go where you wanted. You might do parabolic focused EM waves, like with sound waves for kidney stones. Unfortunately, there's nothing to receive until you hit microwaves (probably bad). I might be missing something, though.

No, I’m probably missing something simple. What do you mean “nothing to receive”? Yes, I was thinking something like parabolically focusing the EM waves.
