How to Measure Neural Tracking Hemispheric Differences

The Q induces alpha suppression in the expected hemisphere, but then as you said, it goes away for whatever reason. It's like they are allocating their attention as desired, but in a very strategic way. And so how about neural tracking? You sort of started to answer this already, but I guess two part question. Firstly, how do you measure neural tracking? And secondly, did you see the neural tracking hemispheric differences that you anticipated?
