The afterglow is real, and often temporary
Research shows this pattern clearly. After a single ketamine infusion, about a third of people with treatment-resistant depression were still responding a week later [1]. In a large psilocybin trial, the benefit was clear at three weeks, while results for sustained response at twelve weeks were less clear [2]. The change is real. Keeping it takes more than the session alone.
A window of plasticity
Psychedelics appear to open a temporary window when the brain is especially able to change. In mice, psilocybin increased connections between neurons within a day, and the increase lasted at least a month [3]. Another study found that psychedelics reopened a period of heightened learning that lasted about 48 hours after ketamine and about two weeks after psilocybin [4].
Old patterns are well practiced
The habits of thinking and feeling that bring people to psychedelic care are often years in the making. They are practiced every day. A single session can loosen them, but without new practice to take their place, the brain tends to drift back toward what it knows best.
What helps change stick
- Repetition during the window. Short, regular practice in the weeks after a session, while the brain is most able to change.
- Structure. A clear plan for the days between sessions, rather than waiting for the next appointment.
- Support. A facilitator or care team who stays involved after dosing day.
- Measurement. A way to see whether the change is holding, so care can adjust when it is not.
Psio is built around exactly these four things: a short daily neurofeedback practice built from your own brain data, during the weeks that matter, with progress you and your care team can see.
