Thresholds Here’s the way I look at the question of automatic versus manual thresholds: 1. Assuming one is talking about amplitude training only (i.e. not synchrony, variability or other options), generally a more healthy and mature brain produces lower amplitudes and lower variability. Even if you say you are training theta down and SMR up, you will most likely see BOTH go down, though theta will go down more, so the relationship between them changes. 2. Since the brain changes […]
