Once a motor or cognitive performance is consolidated in neural circuits, continued mental training and visualization is not necessary to maintain that performance.

“once you have what's called Consolidated the Motor Performance or the cognitive performance of something it can be further supported or reinforced that is Consolidated in the neural circuits that are responsible for performing that mental or physical task so in other words once you are performing that cognitive or motor task in a way that's satisfactory or perhaps just improved perhaps you're not 100% but it's improved in the real world you don't need to continue to do mental training and visualization to to maintain that real world performance”
