Staring does something interesting. It does slowly reduce brain waves, but it is harder to hit theta with eyes open. And it works very differently initially. With eyes closed meditation where we, say, follow the breath we use the salience network to slowly chill the DMN for a bit. When you stare at a wall the salience network is what deactivates letting the DMN rip to try and figure what predictions are useful. But i…
I'm curious what is meant by > ...recalibrates the Salience Network's threshold for alarm. Superficial googling reveals superficial information about the SN. And more specifically, i'm curious what sort of physiological signals could verify recalibration.
Being a modern human is hard. We were not really built for our life post industrial revolution. We evolved to always be ready for threats. The fact that our brains have adapted so well to modern life is amazing and why we have gotten to where we have as a species vs. others. However, it has costs. Our brains our wired to run the DMN loop non stop. So you can do two things. With traditional meditation you make your salience network stronger. Every time your DMN interrupts your meditation and you flex your salience network muscle so to speak you are training it to shift back to the lower DMN activity state. And with wall staring you are changing the brains calibration of what no stimulation means. Both contribute synergistically based on my understanding. (contribute to being less distractible).
