Shortly after Carhart-Harris published his results in a 2012 paper in PNAS {"Neural Correlates of the Psychedelic State as Determined by fMRI Studies with Psilocybin"*}, Judson Brewer, a researcher at Yale* who was using fMRI to study the brains of experienced meditators, noticed that his scans and Robin's looked remarkably alike. The transcendence of self reported by expert meditators showed up on fMRIs as a quieting of the default mode network. It appears that when activity in the default mode network falls off precipitously, the ego temporarily vanishes, and the usual boundaries we experience between self and world, subject and object, all melt away.
