Hjernen er, ifølge hans egne undersøgelse og de kilder han refererer til, så plastisk at personlighedstypen kan ændre sig markant under indtryk af omskiftelige sociale livsomstændigheder og input, men også under påvirkning af mentale teknikker:
In short, the revelution of neuroplasticity has shown that the brain can change as a result of two destinct inputs. It can change as a result of experiences we can have in the world - how we move ande behav and what sensory signals arrive in our cortex. The brain can also change in response to purely mental activity, ranging from meditation to cognitive-behavior therapy, with the result that activity in specific circuits can increase or decrease.
... meditation designed to allow the practioner "to see things as they really are".
... to determine whether and how thousands of hours meditation might change the brain´s structure or function.
... I hoped to see how thousands of hours of meditation alter brain cicuity in a sufficiently enduring ways as to be perceptible when the brain is not meditating.
Han bruger en analogi - det han ønsker, svarer til at ville måle en budybuilders muskler når hans krop ikke er i aktion:
All that exercise enlarges the muscles, and you can measure that even when the bodybuilder is doing nothing more strenuous than lifting a latte.
Mindfullnes retrains thes habit of minds by tapping into the plasticity oft the brain´s connections, creating new ones, strengthening som old ones, and weakening others.That is why we found the brain changes we dit. Our MBSR students showed greater activity in the circuits in the left prefrontal cortex compared to the right, reflecting the fact that people practicing this form of mental training learn to redirect their thoughts and feelings (the physical manifestation of which is nothing but electrical impulses racing down the brain´s neurons) reducing activity in the negative-emotion right prefrontal cortex and ramping it up in the resilience- and well-being left side.This new streambed carries more and more of your thoughts and feelings, creating a virtuous cirkle: The more your thoughts travel along the path of less anxiety, the greater your Reselience and the more positive your Outlook, which makes it easyer for thoughts and feeling to continue takeing this news route.
THE MONK IN THE MASCHINE
Research from other labs had linked the neural synchrony of high frequency brain waves to mental processes such as attention, working memory, learning, and conscious perception; the suspicion is that by fireing in sync, neurons cause far-flung networks to work together, with the result that cognitive and emotional processes become more integrated and coherent.
In the volunteers that experienced insight, Kounios and Beeman found a distinctive spark of high gamma activity that would spike one-third of a second before volunteers consciously arrived at an answer. Additionally, the flash of gamma waves stemmed from the brain’s right hemisphere—an area involved in handling associations and assembling parts of a problem.Gamma activity indicates a constellation of neurons binding together for the first time in the brain to create a new neural network pathway. This is the creation of a new idea. Immediately following that gamma spike, the new idea pops into our consciousness, which we identify as the Aha! Moment.
In addition, Kounios and Beeman noted a burst of slower, alpha-band activity over the right visual cortex—an area of the brain that controls our sight—occurring immediately prior to the burst of gamma waves. This unexpected finding suggests that the brain is quieting the neurons in that area to reduce the amount of distraction and visual interference taken in—similar to everyday circumstances, the way we close our eyes or look away when concentrating on a question—which then allows insight to pop into awareness.
