The team also checked the fMRI readings to determine whether any other brain regions had a similar pattern of activity, which would indicate that the brain networks were communicating with one another.

The study found that under psilocybin, activity in the more primitive brain network linked to emotional thinking became more pronounced, with several different areas in this network — such as the hippocampus and anterior cingulate cortex — active at the same time.

In comparison, activity in the different areas of a more primitive brain network became more synchronised under the drug, indicating they were working in a more co-ordinated, «louder» fashion.

Combining several new techniques, Jonathan R. Polimeni, Ph.D., senior author of the study, and his colleagues at Harvard's Athinoula A. Martinos Center for Biomedical Imaging, applied fast fMRI in an effort to track neuronal networks that control human thought processes, and found that they could now measure rapidly oscillating brain activity.

Well it goes down in the sense [that] it gets a little more focused as well; now know what's happening is this brain dark energy, which scientists call the brain default mode network — and they use the word default because when you're not doing anything else — this is background brain activity that is constantly occurring is all about the brain anticipating and predicting what'll happen next in the environment.
