Took a while to get through the book. I won't summarize it.
One interesting idea not further explored is the finding that sharp Theta waves (p.145-146) on the low end of the Theta range are associated with forgetting, while regular Theta waves, when they occur in a particularly timed pair are shown to be key to forming a stronger synapse, ergo, memories. These 'sharp Theta' waves are associated with meditative states.
My question: could meditative states be a shortcut to important forgetting? i.e. pruning unnecessary memories like unimportant details and distractions?
