quoteBarrett and Griffiths (2017) stated: “Decreased activity in the IPL (and specifically in the angular gyrus), and decreased communication between the IPL and other areas involved in maintaining a sense of self (such as the PCC) are observed both in studies of meditation and in studies of classic hallucinogens.”
claimThe interruption of the Default Mode Network (specifically the posterior cingulate cortex) by meditation, hypnosis, and epilepsy necessitates a general explanation for psychedelic effects within the broader context of altered consciousness.

claimStudies using the posterior cingulate cortex (PCC) as a seed have found increased connectivity with the dorsal anterior cingulate cortex (dACC) and the dorsolateral prefrontal cortex (DLPFC) at rest, and increased connectivity with the dorsal ACC during meditation.
