After the screening, Mettes was assigned to a therapist named Anthony Bossis, a bearded, bearish psychologist in his mid-fifties, with a specialty in palliative care. Bossis is a co-principal investigator for the N.Y.U. trial.
After four meetings with Bossis, Mettes was scheduled for two dosings—one of them an “active” placebo (in this case, a high dose of niacin, which can produce a tingling sensation), and the other a pill containing the psilocybin.

“I felt a little like an archeologist unearthing a completely buried body of knowledge,” he said. Beginning in the nineteen-fifties, psychedelics had been used to treat a wide variety of conditions, including alcoholism and end-of-life anxiety. The American Psychiatric Association held meetings centered on LSD. “Some of the best minds in psychiatry had seriously studied these compounds in therapeutic models, with government funding,” Ross said.

“I’m personally biased in favor of these type of studies,” Thomas R. Insel, the director of the National Institute of Mental Health (N.I.M.H.) and a neuroscientist, told me. “If it proves useful to people who are really suffering, we should look at it. Just because it is a psychedelic doesn’t disqualify it in our eyes.”

I was struck by how the descriptions of psychedelic journeys differed from the typical accounts of dreams. For one thing, most people’s recall of their journey is not just vivid but comprehensive, the narratives they reconstruct seamless and fully accessible, even years later.

This might help explain why so many cancer patients in the trials reported that their fear of death had lifted or at least abated: they had stared directly at death and come to know something about it, in a kind of dress rehearsal.

The default-mode network was first described in 2001, in a landmark paper by Marcus Raichle, a neurologist at Washington University, in St. Louis, and it has since become the focus of much discussion in neuroscience. The network comprises a critical and centrally situated hub of brain activity that links parts of the cerebral cortex to deeper, older structures in the brain, such as the limbic system and the hippocampus.
The network, which consumes a significant portion of the brain’s energy, appears to be most active when we are least engaged in attending to the world or to a task. It lights up when we are daydreaming, removed from sensory processing, and engaging in higher-level “meta-cognitive” processes such as self-reflection, mental time travel, rumination, and “theory of mind”—the ability to attribute mental states to others. Carhart-Harris describes the default-mode network variously as the brain’s “orchestra conductor” or “corporate executive” or “capital city,” charged with managing and “holding the entire system together.” It is thought to be the physical counterpart of the autobiographical self, or ego.
“The brain is a hierarchical system,” Carhart-Harris said. “The highest-level parts”—such as the default-mode network—“have an inhibitory influence on the lower-level parts, like emotion and memory.” He discovered that blood flow and electrical activity in the default-mode network dropped off precipitously under the influence of psychedelics, a finding that may help to explain the loss of the sense of self that volunteers reported….Just before Carhart-Harris published his results, in
a 2012 paper in Proceedings of the National Academy of Sciences, a researcher at Yale named Judson Brewer, who was using fMRI to study the brains of experienced meditators, noticed that their default-mode networks had also been quieted relative to those of novice meditators. It appears that, with the ego temporarily out of commission, the boundaries between self and world, subject and object, all dissolve. These are hallmarks of the mystical experience.

Carhart-Harris doesn’t romanticize psychedelics, and he has little patience for the sort of “magical thinking” and “metaphysics” they promote. In his view, the forms of consciousness that psychedelics unleash are regressions to a more “primitive style of cognition.” Following Freud, he says that the mystical experience—whatever its source—returns us to the psychological condition of the infant, who has yet to develop a sense of himself as a bounded individual. The pinnacle of human development is the achievement of the ego, which imposes order on the anarchy of a primitive mind buffeted by magical thinking. (The developmental psychologist Alison Gopnik has speculated that the way young children perceive the world has much in common with the psychedelic experience. As she puts it, “They’re basically tripping all the time.”) The psychoanalytic value of psychedelics, in his view, is that they allow us to bring the workings of the unconscious mind “into an observable space.”
In “The Doors of Perception,” Aldous Huxley concluded from his psychedelic experience that the conscious mind is less a window on reality than a furious editor of it. The mind is a “reducing valve,” he wrote, eliminating far more reality than it admits to our conscious awareness, lest we be overwhelmed. “What comes out at the other end is a measly trickle of the kind of consciousness which will help us to stay alive.” Psychedelics open the valve wide, removing the filter that hides much of reality, as well as dimensions of our own minds, from ordinary consciousness.
