"Recent developments in neuroscience have liberated both contemplative and psychedelic practices, which have been used for thousands of years to transcend human suffering. Similar brain activity has been found in experienced practitioners of meditation and those under the influence of psilocybin. In this article, I hope to open a door for you to engage your curiosity and continue down the rabbit hole to a more complex understanding of how the self is generated, and how this separation is destroyed. Although subjective experiences may differ, objective data can be obtained from the activity of different brain regions. We can then match the activity of different brain areas with previous research on the behaviour of those with deficits in said region to better understand the function of the structures involved (e.g. when the amygdala and hippocampal neurons fire synchronously, we interpret this as the individual becoming emotionally charged with anger/fear while recalling a traumatic experience). To understand how the brains of meditators and psychonauts are undergoing similar changes, we must understand a recent development in neuroscience related to our “internal chatter” and perception of self in relation to other and time[1]: the Default Mode Network (DMN)"

Even though this article is a bit missleading and also a bit propagandic towards meditation-practices it has some valuable images of the default-mode network.
The issues with the article is that the default-mode network are activated on social tasks and also on goal-directed social tasks, it didnt' inform on that.
Other parts of the brain can be activated at rest too, like when mind wandering and during prospective thinking, it did't include that either.
