posterior parietal cortex and middle cingulate cortex and on the right (ipsilateral) side in the region of the anterior insula, lentiform nuclei, posterior parietal cortex and orbitofrontal cortex ...
These oscillations have many functions in the brain ... caused by psilocybin may indicate that the anterior cingulate cortex transmits and receives less information to and from faraway brain ...
At the heart of this discovery lies a cerebral circuit connecting the anterior cingulate cortex, the hub of numerous cognitive functions, to the brainstem, where automatic breathing regulation occurs.
