The first was that the volunteers depicted their depression foremost as a state of “disconnection,” whether from other people, their earlier selves, their senses and feelings, their core beliefs and spiritual values, or nature. Several referred to living in “a mental prison,” others to being “stuck” in endless circles of rumination they likened to mental “gridlock.” I was reminded of Carhart-Harris’s hypothesis that depression might be the result of an overactive default mode network—the site in the brain where rumination appears to take place.
